The CM0900 controller operates with system voltage from 160 VAC to 270 VAC at 50 or 60 Hz.
The CM0900 controller monitors power sources and transfers between normal and standby power based on preset voltage thresholds and time delays.
The TDES (Time Delay Engine Start) can be adjusted to 2, 5, 10, or 15 seconds.
The build-in un-adjustable overvoltage setting is 270VAC.
