PWRguard protects the radio, the power supply and the battery from damage. It
is an automatic safety switch that is inserted between a power source and the load.
It switches OFF whenever the voltage is over 15 volts or under 11.5 volts. It handles
up to 40 amps, and uses an FET... no relays... to switch.
PWRguard is ideal for use with a PWRgate and a radio. If your power supply loses
regulation and goes high, the PWRguard turns OFF, thereby protecting the radio and
the power supply. If the voltage drops down below 15 volts again, the PWRguard automatically
turns back ON.
If a PWRgate has switched to battery, and the AVERAGE voltage goes below 11.5
volts, the PWRguard will turn OFF, thereby protecting the radio, and preventing
a total battery discharge and damage to your battery. The PWRguard will turn ON
again only when the power supply comes back on.
PWRguard protects a battery from over discharge by sensing the average voltage
under load. Latches off for low battery, and resets automatically if the battery
is re-charged. Ideal for a battery operated ham station.
The PWRguard comes with two 6-inch wires with Powerpole connectors, ready to
plug into the PWRgate and the RIGrunner.
