Sanhe Power Tech SLC Power Factor Correction Controller is a high and low voltage common reactive power compensation controller of dual-core MCU with DSP control, advanced software algorithms and reliable electromagnetic compatibility design. The controller can effectively and reasonably control the shunt capacitor bank switching, improve power factor, reduce line losses, and improve voltage quality.
Main Parameter
Power supply: 100 ~ 260VAC/50Hz, 100 ~ 260VDC
Voltage sampling: 100V, 380V (line voltage)
Current sampling: 5A, 1A
Maximum outputs: 12 (three phases), 15 (single phases)
Output contact capacity: 250VAC, 5A
Dynamic output capacity: 12VDC, 50mA
IP degree of Protection: IP30
Modbus RTU RS485 Protocol
Baud Rate: 2400 4800 9600
Feature
4.3 inch TFT color LCD, English/Chinese menu
Integrated Measurement chip in 0.2 class brings high accurate sampling voltage and current.
Control PF and reactive power together, brings high accuracy and No switching oscillation.
Display system PF, power grid voltage, current, active power, reactive power, transparent power, frequency and each step control status.
Display 2-51 times harmonics voltage, current content rate and charts.
Set parameter easily, no data loss while power off.
Strong record function, i.e. Record information and its time, monthly working times and monthly action times.
Judge and display over-voltage, under-voltage, under-current close, harmonic voltage etc., fast switching off capacitors while abnormal condition.
Set switch status and capacity of each step, automatically select suitable capacity to switch on/off.
Support automatic and hand switch on/off
