Super PowerGate: Part of a Ham’s Home UPS

During our tech net tonight, I couldn’t remember the name or model number of the piece of gear that allows me to have my own uninterruptible power supply (or UPS) to keep all my ham gear running, especially when the lights go off.  So here it is:  The West Mountan Radio PG-40S PowerGate.

Along with a decent-sized deep cycle 12 volt battery (1 or more in parallel) and a 13.8 volt power supply, the PG-40S ties them together to give you uninterrupted power, and also keeps your battery charged, ready for action.  It can provide up to 10 amps charging current to the battery when the power comes back on.  It can handle up to 40 amps, or the equivalent of two fully-equipped HF 100 watt transceivers, or as many as four 50 watt-type VHF/UHF mobile radios.

I’ve had mine for years, and can say I wouldn’t have it any other way.  It’s silent, and the status LEDs on top tell you at a glance what is going on.  The connectors on top are Anderson PowerPoles, pretty much the standard 12 volt connectors in use by all of us these days.  Available at our local HRO stores or mail order.  Price is about $140.  Not cheap, but I can’t live without mine!  We also have this same unit in operation at the WB6ZVW repeater (442.500 MHz, + 5 MHz, 100 Hz PL) on Crystal Peak to handle its battery backup needs.  This one item kept us running without fail during last summer’s big Loma Prieta fire.

One thought on “Super PowerGate: Part of a Ham’s Home UPS

  1. Excellent piece of hardware for the shack. There are 2 versions of this though. There is the PG40 and PG40S. So if you try to pick up one used, on ebay, or a flea market, take note of which one it is. The older and discontinued PG40 only charges at 1 Amp. The PG40S charges at up to 10 Amps (jumper selectable) and also has an internal jumper for the battery type you are using.
