ICM Controls ICM492C Installation guide

Brand: ICM Controls

Model: ICM492C

Type: Installation guide

ICM Controls ICM492C is a voltage monitor that protects single-phase systems against adverse line voltage conditions like over/under voltage and rapid short cycling. It constantly monitors and displays the line voltage on its backlit digital display. The device features adjustable voltage set points, time delay, over/under voltage percentage, control mode, and response time. It has a 5-fault memory storage and universal control voltage input. The heavy-duty SPDT relay output can be used to directly drive loads or control contactors and relays.
