Key characteristics of a power factor controller

The design is entirely digital and uses the AC sampling algorithm.
Four-digit LED digital tube displays or large-screen LCD Chinese liquid crystal displays are used in human-machine interfaces.
Design with a simplified appearance and modular construction
The Modbus-RTU communication protocol is supported with the RS-485 standard bus interface.
Voltage, current, power factor, active power, reactive power, frequency, harmonic voltage, harmonic current, capacitor switching status, temperature, and other parameters are displayed in real time.
The function of harmonious protection
The target power factor cosφ should be adjusted between 0.80 (lag) and 1-0.80 (lead).
Choosing between manual and automatic switching
Support fuzzy control switching mode, coding, and equal capacity
The voltage loss is released when the grid's power supply is disrupted for longer than 15 milliseconds.
It is possible to simultaneously set the output capacity of every output circuit.
It operates in two modes: automatic compensation and manual compensation.
It performs the duties of protection and harmonic measurement.
It features a standard fieldbuscommunication interface (RS-485 Modbus-RTU; optional).
