K8DS-PA 3-phase control
3-Phase voltage, phase sequence, loss and asymmetry
The K8DS-PA is the simplified 3-phase monitoring relay, 3-wire circuits with one unit. It can monitor voltage asymmetry with 3-phase sequence and loss at the same time.
• 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
