Detailed introduction

Product overview

Pro-Con/Dynamic series low-voltage three-phase common compensation power factor controller, using large-screen, white backlight Chinese LCD display. Real-time display of grid power factor, voltage, current, active power, voltage harmonic total distortion rate, current harmonic total distortion rate, frequency and capacitor switching status and other information. A variety of compensation methods and cutting methods, can achieve equal volume cycle cutting, fuzzy cutting and linear cutting. At the same time, it has two working modes of manual and automatic compensation. Extensible communication and temperature protection. The performance of the whole machine conforms to the "DL/T597-1996 low-voltage reactive power compensator order technical conditions". Anti-interference in accordance with GB/T15153.1-1998 Sports Terminals and Systems Part II Part 1 Power Supply and Electromagnetic Compatibility

Product characteristics

4-quadrant measurements and continuous monitoring of inductive/capacitive loads

Reactive power measurement via DFT for use in power grids with high harmonic distortion

Measure, display and monitor line voltage and current, active and reactive power, harmonic voltage and current, line frequency, internal temperature, etc.

Maximum Storage

Adjust target power factor within range 0.80 (lag)-1-0.80 (lead)

Rate change value is input from outside through communication port

Programmable discharge time and ablation delay

Manual cutting can be selected

Up to three fixed adjustment levels can be programmed

After the power grid is interrupted for more than 15ms, the pressure is released.

Target power factor not reached, alarm
