"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."

I needed separate power supply to inverter that controls electronics and laser jet printer within my work truck and didn't want it draining primary battery. The service at Perfect Switch is great. Called only a few times and even when i was installing they were most helpfull on phone all while i was physically installing.

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've had the Power-Gate dual rectifier installed on my '99 Toyota Land Cruiser since 2009 and it has performed perfectly and to expectation for my dual battery set-up.

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.

Power-Gate is the best Switching unit I have come across. It looks great in my custom Toyota Four Wheel Drive Custom 1999' Tocoma. I was easy to install. It is a true military grade switching unit . When it come to having a unit as important as a battery switching unit go with the BEST ... The Power Gate is the best by far..

P.S. I love you! Not the Beatles song but Power Switch I love you!
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.
Respectfully Submitted,
-Ron Wesoloski

This may be a bit wordy....the subject is both simple and complex simultaneously.

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.
