## Description

GKR-02 Voltage Monitoring Device Relay GKR-02 Phase Failure And Phase-sequence Protection Relay For Motor Protection General GKR ve DGR series "over and under voltage" moitoring devices are adjustable "delay OFF"protection devices. they are mainly used for protection for 3-phase and single-phase systems-such as electronic command and control systems,capacitors fo power compensation, switch-boards ,air-condition systems,motors etc. Utilization and Operation Principles For all relays "on" is the supply led "out" is normal led "U>"is over voltage error led "U<"is under voltage errror led 1-When the device is energized for the first time."On" led is ON and if the monitored voltageare within the adjusted range "Out" led is ON and output relay switches ON. 2-When any of the phase/phases fall(s) below the adjusted interval,"U<" error led turns ON,after 0.1-10sec output relay switched OFF and "OUT" led turns OF. 3-When any of the phase/phases exceed(s) the adjusted interval,"U>" error led turns ON,after0.1-10 sec output relay switches OFF and "Out"led turns OFF. look at table 1 *For under voltage monitoring device switched OFF its output relay instantaneously when the measured voltage(s) fall(s) below 50% of its nominal value. For over voltage monitoring device switches OFF its output relay immediately when the measured voltage(s) exceeds 50% fo its nominal value. GKR-02F /GKRC-02F/ GKRC-02FA /GKR-03F/GKRC-03F/ switches off output relay instantaneously in case of incorrect phase sequence then all leds turn off except "ON" led. Technical Data: Rated voltage(Un) Look it the label of the device Rated frquuency 50/60Hz Operating range (0.9-1.1)×Un Voltage adjustment Max: (1,05-1,03) ×Un Min: (0,70-0,95) ×Un Delay time 0.1-10sn.min.(adjustible) Output
