GKR-02F Voltage Monitoring Device

 

 

General:

 

GKR series "over and under voltage" monitoring 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.
