VRD1 Single Ph Under / Over Voltage Relays
| Introduction: |
| It is a 1 Phase Under Voltage Relay. It is best suitable for monitoring 1 phase pump / motor / machine loads powered by Single Phase Generators, UPS, Stabilizers, Inverters or electricity Board (Utility). It is used to protect against fluctuating voltage to start standby generators, to operate mains failure units, Gensets, AMF Panels, PCC, Distribution boards and similar applications, where close regulation is required. Some of the other added advantages are easy & quick settings from front. User friendly indications. DIN-Rail mounting and Panel mounting facility. | |
