| Active Harmonic Filters - AHF |
|
|
DSP based IGBT switched for complete harmonic mitigation |
Product range :
25 to 300 A / 230 - 440 VAC |
Outstanding Features
-
Complete harmonic attenuation from 3rd to 25th harmonic order by closed loop active filtration
- 32 bit TIDSP operating at 120 Mhz Power circuit is built by using high speed IGBTs
- Programmable selective harmonic elimination upto 96% of individual harmonics
- PF correction - leading lagging possible, selection between PF and harmonic compensation possible
- Modular design, paralleling of individual units possible for higher ratings
Complies to IEEE519 for low frequency harmonics, EMI complies to IEC62040 part 2 for CL A restricted use
- All front display parameters including waveforms can be monitored through PC
- Self current limited, if overloaded, current limit is automatically modified if used at higher ambient temp.
- Can be used as Hybrid filter - can be used along with passive filter to reduce size and make it cost effective
