Product Name: 400VAC 50Hz 500A active harmonic filter
Model No.: SAPF-500/400
Input Voltage: 400VAC
Frequency: 50Hz
Compensating Current: 500A
Size: 1000*1000*2200mm (W*D*H)
Cable Entry: Top / bottom
Installation: Floor standing
Electric System: 3 phase, 3 wires / 3 phase, 4 wires
Working Principle: Active harmonic filter (also called active power filter ) is paralleled between grid side and load side, and can follow and compensate the dynamic harmonic current rapidly, measures harmonic current by CT, and actively calculates each order harmonic current by DSP control system, and then it generates a current with phase that is opposite to the measured distorting harmonic current, which cancels out the original harmonics.
Features
1. CT ratio: 150:5 ~ 6000:5.
2. Compensated harmonic orders: From 2nd to 50th order, efficiency up to 95%. All filtering or selective filtering for option.
3. Response time: < 10ms.
4. Power factor correction: Yes, and can be set.
5. Current limitation: Yes, at full automatic correcting, 100% rated output.
6. Parallel: Yes, several units can be connected in series.
7. Switching frequency: 20KHz.
8. Communication: RS232 / RS485.
9. Cooling method: air cooling.
10. Not only eliminates harmonic current from the load side, but it also eliminates grid side harmonic voltage caused by harmonic current, as well as the harm caused by harmonic current and voltage.
11. Can also generate reactive power and imbalance compensation currents, which can cancel existing reactive power and imbalance currents in the system.
Service Condition
1. Ambient temperature: -10℃ ~ +40℃.
2. Relative humidity: Less than 85%, non-condensation.
3. Altitude: Less than 2000m. (more than 2000m should be with special design.)
4. Installation site: Indoor service. Vertical inclination shall be less than 5 degree. No fire hazard, explossion risk, conductive dust, corrosive gas and strong vibration exist.
