Product Description

APFM
Series Active Power Filter Modlule
Rated Voltage: 0.4kv
Rated Frequency: 50HZ
Function:Sanhe power APFM series active filter module detect load current through the current transformer,then calculate by the means of the internal DSP, extract the harmonic components of load current, and send PWM signal to the internal IGBT, control inverter to produce a load harmonic current equal in size, in the opposite direction of harmonic current injected into the power grid, to achieve the purpose of filtering.
Application: widely used in industrial and commercial power users.
Installation: indoor

Product feature

Compact and reasonable structure, flexible installation

Advanced control algorithm, software reliability

DSP+FPGA control system adopts vector screening technology

Dynamic filtering of 2 ~ 51 harmonics, but also selective filtering of specified harmonics
Harmonic compensation, reactive power compensation and three-phase unbalance compensation

A variety of capacity modules, any capacity combination parallel, good expansion performance, to meet the needs of different capacity system

Use standard communication port and protocol

Fault alarm and record function, up to 500 alarm records

Complete and effective protection measures, such as over voltage protection, under voltage protection, short circuit protection, inverter bridge reverse protection, over compensation protection

In the process of load change, if there is resonance,APFM will self-judge and exit the system, and alarm at the same time to avoid fault
