Model 1000 power inverter/backup system is designed to provide backup power for your vehicular gate operator and access control system when primary (AC) power fails. Unlike DC Gate Operators that can only back-up the gate operator itself with internal batteries to run the DC motor, model 1000 converts DC battery power to AC power to keep all system components, even the ones that are powered by AC accessory transformers, operable at all times. DC gate operators do not convert their battery power to AC, rendering all AC components of your system inoperable. Selectable power out/power start options. Selectable continuous operation mode or quick open mode. Modified sine-wave or pure sine-wave output models available. Electronic control circuit monitors battery voltage while system is in inverter mode and commands gate operators to open when battery power reaches critical levels.
