product features

1, fast and accurate response
adopts instantaneous reactive power algorithm, which can quickly extract load reactive power current in real time, enhance the dynamic compensation capability of reactive power current, and quickly track the change of reactive power current for real-time compensation when the load environment changes.

2, reactive power compensation effect is remarkable
can dynamically compensate the reactive current of the system effectively, and the reactive power compensation rate is ≥ 99% .

3, high harmonic filtering rate
can filter 2-25 harmonic currents at the same time, or select any harmonic current for compensation as required.

4, omni-directional compensation function
can realize multi-functional compensation of reactive power, harmonic and three-phase unbalanced current, and can set the priority of each function according to the load environment and requirements to realize omni-directional compensation of power quality problems

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

6, layered heat dissipation structure design
adopts the structural design concept of layered heat dissipation, and uses independent air ducts for forced air, which effectively isolates the interference of dust on the control system and facilitates the centralized air cooling and heat dissipation of power switch tubes and inductors.

7, modular design
modular system, each independent operation mode will compensate reactive current sub-modules, to ensure that other modules can continue to compensate when a single module is damaged, online replacement of modules does not affect the management of reactive current, and the guarantee of power quality is uninterrupted.

8, high density and high protection grade design
Can achieve a reactive power compensation capacity of 800kvar per single cabinet: careful three-prevention design or glue filling process design is adopted, so that the product can still operate without interference and reliably in harsh environments with more conductive dust such as silicon powder and graphite powder.
