Liebert AC3

This product is discontinued.

Liebert Autochangeover Controllers monitor running and stand-by environmental units for proper operation. The AC3 Autochangeover Controller provides coordinated control in systems with redundant environmental units. When an alarm is detected in a Running unit, the AC3 enables a Standby unit and responds to the unit in alarm as programmed. The AC3 controller also can balance the run times of the units, by rotating the Running and Standby assignments.
