Features

The reactive power compensation controller HJKL is a specified controller that can match all kinds of capacitors in a low-voltage system. It adopts MCU controlling and uses numerical techniques to compute the phase difference between the fundamentals of current and voltage, enabling precise power factor measurement with quick response.
Operating voltage：Rated operating voltage: AC380V15% , AC220V15%
Operating frequency：50Hz /60Hz, allowable deviation 5%.Input current：Direct access ≤ 5 AMeasurement display electrical parameters：Voltage, current, reactive power, power factor, voltage harmonics, current harmonicsDisplay mode：4-bit integrated Digital Tube Display (LED)Relay output：4 loop, 6 loop, 8 loop, 10 loop, 12 loop, single pole passive output, Contact capacity: 5A @250VAC, 5A @30VDCSwitching mode：Manual/automatic (cycle switching, optimization switching)Dynamic response time：≤1sCommunication and Protocol：Communication port: RS485 ，Communication protocol: MODBUS-RTUFunction Protection：Over-voltage and under-voltage protection, Undercurrent protection, Over abnormal rate alarmAmbient temperature：-25~55℃Relative humidity：No more than 50% at 40℃ and no more than 90% at 20℃Panel protection rating：IP40

Benefits

Classic Appearance: Four-digit LED version dynamic display. High enlivenment compatibilityAdvanced Feature: Various switch logics(Cosφ, Reactive power); Hamonic detective function; Communication function new integrated.

Applications

AN EXCELLENT CHOICE FOR ALL STANDARD APPLICATIONS, INCLUDING: ​- Low-voltage distribution cabinet- Reactive power compensation cabinet- Package substation

HJKL & HJKF: 12 steps

HJKL: No
HJKF: RS485 (via MODBUS)

HJKL: Temperature sensor installed in transformer to trip the circuit directly once temperature exceeds 105             degree celsius
HJKF: Temperature sensor welded in PCB to monitor the ambient temperature of the controller; once the             temperature exceeds 65 degree celsius, alarm and capacitor disconnection will happen then.
