Product details

The Omron K8AK-VS3 24VAC/DC is an active voltage sensing relay in the K8AK series, set for DIN rail mounting with an adjustable trip range of 20 to 600 V AC/DC.

The SPDT output (1 Form C) switches up to 5 A at 250 VAC. The adjustable delay from 0.1 to 30 seconds lets you ride through short voltage sags without tripping, which is useful on generator startup or transformer inrush where voltage dips are temporary. Supply voltage is 24 VAC/DC, so it can be powered from a common 24 VDC power supply or a 24 VAC control transformer without a separate module.

DIN rail mounting fits into enclosures alongside contactors and terminals, for undervoltage or overvoltage protection.

Frequently asked questions
