DESCRIPTION
DuraComm’s LPB-12M power supply is pre-set to convert 100 to 260 volt 50/60 Hz AC power to low noise and ripple 13.8 volt
DC power. The AC input is auto-ranging and can be used without any changes. The power supply also contains a built-in, replaceable
sealed lead acid battery that automatically takes over should AC power be disrupted. The DC output operating voltage from the internal
battery and AC charger circuitry is delivered to the terminal strip located on the rear panel. The from panel meter shows DC voltage
output and battery level. The power supply DC output is protected against inadvertent shorts and overloads by a thermal circuit breaker.
