K8DS-PM 3-phase control
3-Phase voltage, phase sequence, phase-loss and over-/
undervoltage relay
The K8DS-PM is the simplified 3-phase monitoring relay, 3-wire circuits with one unit. It can monitor undervoltages, overvoltages, 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
