Relay to protect devices with sensitive operating voltages and undervoltage from caused by network voltage disturbances. Single-phase. Manufactured by TENSE.
Detailed description
Monitoring overvoltage and undervoltage relay GKM-11, single-phase
Adjustable voltage protective relay GKM-11 (surge and undervoltage) is designed to measure voltage as a prevention of faults by disconnecting the relay (disconnecting the load) in single-phase distributions, switchboards, and devices. It monitors the voltage level in a single-phase the system between L-N.
Using of rotary potentiometers It is possible to set the upper and lower voltage limits at which the relay output contact disconnects. Adjustable time delay "DT" and "RT" allows eliminating too rapid unsolicited response. Power is internally connected from the monitored voltage. The normal state is indicated by a green LED. An error state is indicated by 2x red LED "LV" and "HV" and the disconnection of the relay output contact.
