TIGE Wakeboard Boat...problem solved

Just wanted to let you guys know that the SR-150 showed up today. It
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.

I wish Tige would use your products on all of their boats.

Thanks for an amazing product!

MasterCraft X-80, High Power Audio Install

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.

Manufacturing Test System

Pyro Test designs turnkey test systems for manufacturing. In this case, our end application called for us to create a manufacturing test system that would produce, upon demand, any current from 200 mA to 350 Amps (and that was the easy part). The hard part was finding a way to switch-on the current, cleanly, with a very fast slew rate (i.e. go from 0 to 350 amps in less than 500 us) while still providing a switch resistance at least 100 times less than the nominal E/I (in our application, we could not afford to drop any significant amount of voltage across the switch). The POWER-GATE was the only switch solution which would work for our application. We contacted the folks at Perfect Switch and worked directly with one of the design engineers in order to verify that the POWER-GATE would indeed work for our intended application.Our final test set solution included several non-inductive load trays switched by the POWER-GATE product (see photo). The completed system has been up and running without a problem since we installed it on the factory floor. The end-client (a very large and well known company) was exceptionally pleased with the test system. I'm happy to report that, because of our outstanding success with this first product, we have been awarded a second purchase order from our client.

Bell Fleet Application

We use an Onan 5.5 KW generator. The Trojan 4D AGM battery powers the generator set and runs some of the vehicle's off road lighting. The battery is charged by the Ford's 130 Amp alternator and the POWER-GATE isolates the vehicle batteries and the 4D. The setup works great.

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.

I have (truck) 14672 all working now so come and take a look and see if I overlooked anything. The output on this new alternator is impressive and so is the POWER-GATE.
