Power Inverter & Backup Systems

The Model 1000 Power Inverter provides backup power for a single-gated Access Control System when primary AC power fails. Maintain a fully operational Access Control System during power outages and brown-outs. Ideal for residential and commercial applications with a single-gate system.

Power Inverter & Backup Systems


No Power, No Problem

DoorKing’s Model 1000 Power Inverter and 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, the 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.




Power Outages

Model 1000 can run your Access Control System during power outages.

Maintains power to all components of the Vehicular Gate System including the Gate Operator, Loop Detectors, Secondary Entrapment Prevention Devices, Telephone Entry System, Card Access System, RF Controls, etc.



Suitable for use with DoorKing Class I and Class II gate operators and most other residential / light commercial gate operator brands.
