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
•OneSPDT output relay, 5 A at 250 VAC (resistive load)
• World-wide power specifications supported by one unit (Set with a rotary switch)
• Relay statuscan be monitoredusing LED indicator

Asymmetry operation
(ASY.)
Operating value setting rangeAsymmetry rate: 2% to 22%
Operating value100% operation at set value
Asymmetry operating value = rated input voltage x asymmetry set value [%]
The asymmetry operation will function when the difference between the highest and lowest voltage phases equals or exceeds the asymmetry operating value
Reset (HYS.)Hysteresis 5% of operating value (fixed)
Resetting methodAutomatic reset
