Numerical AC DC Supervision Relay – GKDCSR

Continuous Supervision of Auxiliary Power Supply

GKDCSR is a dedicated AC-DC supervision relay specialized for continuous monitoring of the AC and DC auxiliary power supplies. In case of any power source failure, it must be alarming and also initiate tripping within the crucial time, even if all other protection relays fail due to power supply failure, to ensure safety for everyone.

GK Power, an RDSO-approved leading manufacturer in India, offers a numerical AC DC supervision relay at the industry’s latest technology. Enhanced safety by reducing hazards with safety-conscious testing of IEC 60255-1, IEC 60255-26, and IEC 60255-27, this relay unleashes its own full potential of working in hard environments with ingress protection of IP54.
