Harmonic compensation:
EAPF can filter out 2~50 harmonics at the same time, or selectively set the number of harmonic current compensation and the compensation rate of each harmonic according to needs.
Reactive power compensation:
Capacitance sensitivity (-1-1) stepless compensation, PF1.00 perfect reactive power compensation effect.
Three-phase unbalance compensation:
Three-phase active power unbalance compensation, three-phase reactive power unbalance compensation, split-phase compensation.
High efficiency£¾97%
The unique multi-layer space heat dissipation, advanced design, and excellent material selection make the whole machine work efficiency higher than 97%, and the loss is smaller.
THDi<5%
The powerful computing power of DSP, the logic control function of CPLD, and the fast on-off speed of GBTM up to 35KHz enable the full range of EGA products to achieve THDi<5%o
Filter 2~50 harmonics
Using modern power electronic devices and high-speed DSP digital signal processing technology and CPLD complex programmable logic devices, APF can handle 2 to 50 harmonic compensation at the same time, and the compensation order can be specified.
Free parallel expansion
25-100A five capacity modules, any capacity combination and parallel, single cabinet capacity up to 600A, to meet the needs of different capacity. Any module can realize all functions, if any module has a problem, the other modules can operate normally to ensure the continuity of the safe operation of the system.
£¼50 |J S quick response
The digital signal processing technology of high-speed 32-bit DSP+CPLD all-digital control mode realizes fast response less than 50ms.
Resonance monitoring:
In the process of load change, if resonance occurs, APF judges itself and exits the system, and alarms at the same time to avoid malfunction.
Temperature monitoring:
Real-time monitoring of the temperature of the ABC three-phase heating components (IGBT and inductor), when the temperature is too high, an over-temperature alarm will be issued, and the compensation will be automatically shut down.
surveillance system:
APF monitoring system, users can clearly understand the system waveform diagram, spectrum diagram, current effective value before and after compensation, THDi, THDu, power factor, active power, reactive power, apparent power
Human-computer interaction system:
The APF has a human-machine dialogue monitoring system, intelligent management, friendly communication interface, large LCD screen and LED status lights; all operations and settings of the machine can be completed by moving up, moving down, confirming, and canceling four keys, which is simple and convenient.
Learning function:
With the EAPF monitoring system, users can clearly understand system waveforms, spectrograms, current RMS, THDi, THDu, power factor, active power, reactive power, and apparent power before and after compensation.
Multiple monitoring methods:
EAPF is equipped with a variety of monitoring methods for different models, including 3.8-inch LCD display, 4.3-inch touch color screen, 8-inch full-color LCD touch screen and background monitoring software to meet the different needs of users.
