Active Power filterActive power filter (APF) is designed to filter the harmonics injected by non-ads in power networks. It can analyze the ent harmonics drawn by the loads and generate a compensation current dynamically at the opposite se angle, thereby "neutralizing" the harmonic currents.
Features 1. Based on 3-Level topology circuit 2. Modular design for a shorter delivery cycle and easy maintenance. 3. Rack-mounted or wall-mounted design which can be easily combined and installed as needed. 4. It is possible to compensate the 2nd~51st harmonics, or select a specific order of harmonics to compensate separately. 5. Flexible compensation modes: Harmonic compensation,Reactive power compensation, Three se imbalance compensation 6. Harmonic +Reactive power +Imbalance 7. Remote communication interfaces, with real-time monitoring being achieved via PC machines.8. A full automatic detection runs during the whole compensation process, and should it be restarted, self-diagnosis will function; then after the fault is removed, it will be automatically put into use. 9. Free of harmonic resonance.10.A user-friendly human-machine interface is configured to operate, and display system's real-time parameters like voltage/current waveforms, active power, reactive power, apparent power, power factor, harmonics, etc. 11. Intelligent control circuit with perfect protection functions (against overvoltage, under voltage, over-heating, over current, etc.)Technical SpecificationsItems Module capacity:25A/35A, 50A/60A, 75A/100A Power supply voltage:400V (-43%~+14%) Power supply frequency:50/60Hz (Range: 45~63Hz) Wiring method:3P3W/3P4W Harmonic spectrum:2nd~50th Harmonic setting:All harmonic contents can be selected simultaneously Efficiency:Up to 98% Filter performance:THDi<5% Neutral filtering capacity:Three times of rated current Response time:<15ms Reactive time:<50microsecondResonance protection:YesCooling mode:Forced air cooling Operation mode:Harmonic compensation(FFT analysis, instantaneous reactive power), Reactive power compensation (-1~+1),Three se imbalance compensation Switching frequency:20kHzPower loss:<3% Communication interface:RS485 (Modbus RTU), TCP/IP (Ethernet) Digital I/O:4DI/6DO Alarm events:YesMonitoring:Via centralized monitoring PQ viewer Mounting type:Rack/Wall mounted Protection level:IP20 Altitude:1500m, if >1500m, the power decreases by 1% every 100m.
