K8DS-PU

3-phase undervoltage and phase-sequence phase-loss relay

The K8DS-PU is the simplified 3-phase monitoring relay, 3-wire circuits within one unit. It can monitor undervoltages, phase sequence and phase loss.

Greater resistance to inverter noise
One SPDT output relay, 5 A at 250 VAC (resistive load)
World-wide power specifications supported by one unit (Set with a rotary switch)
Relay status can be monitored using LED indicator
