The IK 9173 and SK 9173 voltage relays in the VARIMETER series monitor AC voltage networks for undervoltage. The measurement is very simple and does not require a lot of wiring, as no separate auxiliary voltage is required. Early detection of impending failures and preventive maintenance prevent costly damage and, as a user, you benefit from the operational reliablility and high availability of your system.
Features
- According to IEC/EN 60255-1
- Monitoring of undervoltage
- Without auxiliary supply
- Optionally fixed or settable response value
