Lowell W. works in Tanzania for an NGO.
So happy to have been a customer all these [eleven] years.
Very happy with my purchase and all the good service it has provided.
I estimate I have pulled my trailer over 125,000 miles and the Perfect Switch has done its job all the way.
Will be happy to have it aboard the new rig, even in a different role! (Lithium-Ion battery application)

We were using Sure Power isolators for a relatively high demand electrical system. With just 8 prototypes in the field, we had 100% failure rate and less than desirable service from the manufacturer. I found POWER-GATE on-line in a Google search. It looked to be able to provide everything we needed. I called in and discussed the application. Service was prompt and professional. It is a considerably more expensive product than the Sure Power but we have been up and running for several months with no issues. Installation was easy and I would definitely recommend.

I got a Dual Rectifier Power Gate for a competition audio system in my truck. Unlike most isolators, the almost non-existent voltage drop really gets the judges attention. It works flawlessly. Very well built and extremely compact. I would recommend these to anyone.

I've purchased 20+ isolators and bi-directional relays over the past 5 years for our fleet at University Laundry. These units have performed extremely well in various climates across the country. I really like how easy the units are to install. Once it's installed they don't require any maintenance or monitoring. We've been using the first isolators we purchased for 5 years and they are still running strong. Many of these units are mounted to the frames of our trucks and exposed to the elements. What is even better than the products is the customer support. Seriously, when the company owner replies to calls and emails, many times within minutes, I couldn't ask for more as far as customer support. I've recommended Perfect Switch to weekend adventurer trying to maintain batteries for camping and winching to the over the road driver powering everything on his rig 365 days a year.

The POWER-GATE was the perfect solution. After checking the voltage at each connection, I find that I lose less than .05 volts through this device. Outstanding! Installation and connections were a breeze. Another neat feature is the battery combine feature. I used to carry jumper cables just in case I needed to jump-start the starter battery from the Aux battery. With POWER-GATE, I installed a momentary switch on my dashboard that combines the batteries briefly if I ever need to jump start the boat.
All in all, this is a more pricey device, but it is the very best. That's why I bought it and that's why you should buy it. No more worrying or electrical issues to deal with, just fun on the water :)
Fortunately, my skepticism was overridden by the explanation of the design by speaking with a representative. Though still skeptical about the price, I ordered it anyways. After an easy installation, I was (and still am) blown away by the remarkable difference in performance of the unit and how it has saved me so much fuel idling to recharge the system during the day.
Put your skepticism behind you. It would be much more expensive NOT to purchase a POWER-GATE and opt for a lesser design. There IS a difference and I would recommend this company any their product to anyone who has an auxiliary system for power. Higher efficiency, less heat, more voltage, better battery life and much, much lower operating costs.

"Primero que nada quiero mencionar que yo me encuentro en México y adquirí el producto directamente con Scott. Estoy muy satisfecho con el producto adquirido con POWER-GATE que fue un diodo rectificador sencillo, el servicio fue muy bueno desde que me puse en contacto con Scott, en mi caso ya sabia exactamente el producto que necesitaba, pero aun así me proporcionaron información técnica del diodo el cual use para la instalación de una batería de respaldo para un procesador montado en un equipo que se usa para estudios de pavimentos, el diodo fue muy fácil de instalar, y hasta el momento sigue funcionando a la perfección, sin duda recomendaría a POWER-GATE por su buen servicio y calidad en sus productos."
"First of all I want to mention that I am in Mexico and purchased this product directly from Scott. I am very satisfied with the product purchased with POWER-GATE [which] was a simple rectifier diode, the service was very good since I got in touch with Scott, [and] in my case [he] knew exactly the product I needed, but still provided technical information [to] use the diode [and] install a battery backup for a computer processor used for the study of pavement. The diode was very easy to install, and so far it is working perfectly. I would definitely recommend to POWER-GATE for good service and quality products.

Installation was so easy i was scared i was doing it wrong and that's why I called.
I would recommend POWER-GATE to everyone who needs superior switched power product.
I considered other isolator systems but liked the overall simplicity, small form factor and customer service promise from Perfect Switch. I did have a few questions during the install process which Scott answered very quickly.
I have and will continue to recommend the Power-Gate battery isolator systems based upon product performance and the commitment of Perfect Switch to the end-user.
After major inquiries and web surfing into a battery charging station used in conjunction with my house battery, an odyssey, I have found the no maintenance reliability to be exceptional.
After a night of watching TV with the inverter I can start up and travel knowing that the battery will be fully charged when I stop for the night.
Installation was easy, I let my RV repair shop perform the installation along with other work I was having done. Quite a few of the staff asked me where I purchased the unit and I explained that every Class A and C unit they sell should have one installed. I also expressed my concern over old style battery charge splitters to be obsolete with the P.S. Power Gate. I hope they listened to my "endorsement" of your product. They did want me to get back to them after I've tested the Power Gate. I gave the unit a very high reccomendation.
Hi, Perfect Switch, LLC:
My name is Ron Wesoloski, and I am the RF Engineer responsible for Microwave Communications and Renewable Energy Systems for Cellcom's wireless communications systems in northeast Wisconsin and Michigan's Upper Peninsula.
We chose the POWER-GATE for one of our renewable energy cell sites located on an island.
This site needed to have 2 separate deep-cycle battery banks coupled together by a POWER-GATE device. This device allows charging of both battery banks and yet isolates the smaller of the 2 for critical loads, such as the Microwave Link and the Remote Monitoring/Control Systems at the site, from our headquarters in Green Bay, Wisconsin.
The device installation went very smoothly, with a couple of mounting screws and 2 power terminals to connect. Since installing this device, the 24x7 Microwave Link and the Remote Monitoring/Control Systems have never gone down, even though a few times the larger battery bank has discharged to the point where the low-voltage-disconnect activated and shut off all of the other, larger loads that run 24x7 otherwise. It has operated without any issues whatsoever since it was installed back in 2009.
We would recommend the POWER-GATE to others using, or thinking of using, a dual-battery bank, which is especially important for renewable energy systems.
I chose to purchase the Power-Gate MosFET battery isolator even though the initial capital expense was easily three-fold that of the competition through normal auto parts suppliers. For me the choice was simple....superior power handling and longevity -vs- price alone. When the standard isolator fails in service, the failure mode is normally a short rather than an open circuit...this mode leaves the alternator and BOTH battery banks connected as if there were NO ISOLATOR in the loop. The normal result is then to see your alternator fail shortly thereafter without warning. One additional technical consideration that weighed heavily on my choice was the superior current handling (measured as a voltage-drop at the isolator) that the POWER-GATE provided....literally, the drop is too small to measure without especially sensitive test equipment. This means that the output from my alternator is properly delivered to the DC distribution network downstream without loss to heat generated by the battery isolator itself....this is why the POWER-GATE doesn't require a big multi-finned aluminum heat sink to survive. I did make one significant change to my downstream DC wiring for the chassis battery bank....I replaced the factory original #6 gauge cable run from the isolator to the starter post (where it ties directly to the chassis battery) with a high current #0 gauge multi-stranded cable with soldered lugs. Again, the result was to minimize resistance-induced heat and voltage drop losses.
Would I recommend this device to other RV installations? Absolutely!!! The tour I got of the facility where these are made completely convinced me of the quality and capability that the POWER-GATE provides....my unit was documented in testing prior to delivery as capable well beyond the 140 Amps my alternator provides (a close to 30% over-amperage capacity). The firmware programming (that's right, it's a smart device) that allows for exciter voltage to be delivered to the alternator on startup is brilliant....and still retains full protection against reverse current flow to protect the regulator circuitry within the alternator.
I found it simple to install, much more compact than the unit it replaced, and so well-engineered as to provide me with a sense of confidence that it will last longer than the vehicle itself.
So, if your RV utilizes a conventional (finned) battery isolator and you want to make your system better, this is a great alternative.

So how does one define or measure the "best" battery isolator if every manufacturer claims to offer the "best." From our perspective, it's very simple: to measure the efficiency of isolators (also known as rectifiers), you need to know what the voltage drop is at a given current level. Many companies try to impress buyers by offering a zero or no-voltage-drop isolator. This of course defies the laws of physics, but they hope the buyer doesn't know that.
At very low current levels, the voltage drop through any isolator will be very low. But what is the voltage drop at 100 amps? 200 amps? or 300 amps? The voltage drop at these elevated current levels is what truly makes POWER-GATE "best." And we say that not because we are arrogant, it's because the numbers don't lie.
Perfect Switch, LLC owns the patent on a unique assembly process where the use of arrayed MOSFET's yields the absolute lowest resistance from the input to the output of a device. The resistance is so insignificant that heat sinking and airflow are not necessary. So as you compare devices for your DC power management needs, if it looks like a giant heat sink, it does so for a reason....to dissipate heat. If it were a "zero voltage drop" device, it would dissipate no heat and if it dissipates no heat, why does it look like a giant heat sink? If it looks like a duck and quacks like a duck, you guessed it....it's a duck.
We've scoured the earth looking for competing technologies and we can say with absolute certainty that when you buy a POWER-GATE battery isolator, or you add a POWER-GATE solid state relay to your electrical system, you are buying the "best" that technology has to offer.

I am writing to let you know that I received the Perfect Switch that I ordered and I now have it installed in my 1991 Chevrolet G30 Sportvan. I want to thank you for all of your knowledgeable help and great conversation. The switch is working just as you describe....."Perfectly". I could not believe my eyes when I checked the voltage drop and it was practically zero. The installation was also as you described, simple and straight forward. There are not too many products that anyone can proudly boast about anymore, but you can be assured that this is definitely one of them. American made and top notch! I will be recommending the "Perfect Switch" to everyone I know that needs a dual battery set-up. Thanks again and keep up the great product development.
Best regards,Carlos Baez

was a breeze to install and was an amazing improvement over the
Charles Marine Isolator that was originally installed. Our customer
had a low voltage complaint and I was seeing .75 to 1 volt lost at the
isolator. Now my voltage at the dash is over 13v where before it would
max out at less than 12v.

There are five Digital Reference Zapco amplifiers. There is a DC1000.4 on the rear speakers and half of a DC1000.4 running the front speakers. The other half of the DC1000.4 is bridged to one of the three tower speakers while there is another DC1000.4 bridged to the other two tower speakers. On the two 12's there is a DC1100.1 on each. Every speaker in the boat runs at 4ohm to help with heat and power consumption. The interior components are getting 150 watts each, the towers are bridged at 500 watts each and the subs are getting 820 watts each. The amps are layed out one on top of the other with lit plexi in-between. the component crossovers are at the top of the rack. The tower... there are 2 PRO 80's and 1 PRO 485 painted red. The bar that holds the speakers was machined out of aluminum and anodized clear(for corrsion). Two X's were milled in the bottom to match the boat. The mounts on the bar were made for the newer X-80 towers with the speaker mounts, but. The boat came with a 95amp alternator for each motor. The customer's request was for the longest possible playing time with the motors not running. So we installed 4 Stinger SPV70 batteries (I ran out of 3 hour blue tops). Three of the batteries are for the system and one is for the boat. The hang up with using such a big battery system is that when they run below 10 volts, they require alot of current to charge back up. After going back and forth with Wrangler Northwest, we came up with a solution. The two factory alternators were replaced with a 160amp Balmar unit. In order to insure that there would be no charging issues, we would have to get the most current to the batteries as possible. The two charging systems were combined with "POWER-GATE" Isolators for 320 amps of charging current. Basically, they are like big smart diodes. The system works perfectly. All of the charging/ground cables were upgraded to 0awg. Custom battery trays were machined for each side of the boat.

I had a meeting with our Fleet managers in Ontario and they are sold on the POWER-GATE technology. It has been decided that Bell vehicles will integrate the P-GATE into the Isolator replacement program. I will advise purchasing that we will enter the switch into the parts replacement catalogue and we will advise our main parts supplier that we want to stock this switch to replace all standard isolators when required.Regards,
