product features:

1, intelligent dynamic balance adjustment
adopts instantaneous reactive power algorithm to improve the fast real-time performance of unbalanced current extraction and enhance the dynamic compensation capability of unbalanced current. when the load environment changes, it can automatically adjust and track the change of unbalanced current for real-time compensation.

2, two-way reactive continuous compensation
can adjust the inductive or capacitive reactive current in real time according to the actual situation of the load, dynamically and continuously compensate reactive power and improve the power factor.

3. Voltage stability support
Real-time monitoring and improving voltage quality, stabilizing system voltage, improving power distribution quality and improving power consumption environment.

4, filter current taking into account governance
adopts high-precision harmonic extraction algorithm to dynamically monitor the harmonic current of the load, which can track and control the harmonic current in real time.

5, three-level power conversion design
adopts advanced three-level NPC topology. Compared with the traditional two-level topology, the waveform is closer to sine wave, and the reverse voltage borne by the switch tube is half of the DC bus voltage, which is equivalent to improving the switching frequency, with small ripple current and faster current response speed.

6, layered heat dissipation structure design
adopts layered heat dissipation structure design, adopts independent air duct for forced air cooling, effectively isolates the interference of dust on the control system, and facilitates the concentrated air cooling and heat dissipation of power switch tube and inductor.

7, humanized interactive interface design
adopts high-brightness industrial 5.7-inch touch LCD screen, graphical interface design, simple and intuitive humanized design, which can enable users to operate freely, monitor the running state, compensation effect and abnormal situation in real time, avoid resonance of the system and record the resonance situation, so as to better compensate.

8, remote wireless communication monitoring
adopts low-power industrial GPRS and Wifi wireless communication design, supports common communication protocol, and realizes convenient remote monitoring.

9, high protection design and installation
protection level up to IP44, to adapt to different outdoor load environment installation requirements.

10. Real-time data recording
Fixed-point recording of real-time data to provide all-round power quality monitoring and management analysis.
