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.
