Product Description
Floor Standing 125A Active Harmonic Filter AHF Cabinet 400V High Protection IP54 Power Quality Equipment
The ND-APF-125-FS is a 125A floor-standing cabinet developed by Shanghai NengDu for low voltage power quality correction. As a true Active Harmonic Filter AHF, it detects harmonic currents in real time and injects equal and opposite compensation currents into the network, canceling harmonics at the source. This Active Harmonic Filter AHF eliminates harmonic oscillations, reduces electricity costs and protects transformers, cables, capacitors and motors from overheating and premature failure.
Product Introduction
The ND-APF-125-FS Active Harmonic Filter AHF is a multifunctional solution based on a high-speed DSP controller and IGBT power stage. It can be easily customized to provide power factor improvement, voltage change control, flicker mitigation and load balancing functions, greatly improving the power quality in the network while reducing harmonic pollution. Positioned between the standard module and the flagship cabinet, this 125A floor-standing Active Harmonic Filter AHF unit offers an optimized balance of capacity, cost and protection for 400V three-wire industrial networks. The IP54 enclosure allows installation in demanding environments with dust and moisture.
Every Active Harmonic Filter AHF unit is factory calibrated and fully tested before delivery. The user-friendly touch screen displays real-time harmonic spectra, compensation current, system voltage and fault records, while the RS485 interface allows remote monitoring and integration with plant power management systems.
Key Features
- Precise harmonic filtering: Effectively eliminates 2nd to 50th order harmonics with high accuracy, keeping THDi below 5 percent even under rapidly changing loads.
- Fast response and dynamic compensation: Real-time current detection with a response time of less than 10ms ensures the Active Harmonic Filter AHF reacts instantly to load changes.
- Multi-function integration: Simultaneously compensates harmonics, reactive power and three-phase unbalance, improving overall power quality in the network.
- High safety and stability: Active injection technology creates zero resonance risk with the power system, protecting sensitive equipment from harmonic amplification.
- Compact size and flexible installation: Small footprint and flexible mounting options make the Active Harmonic Filter AHF suitable for limited spaces and retrofit projects.
- Strong adaptability: Automatic adjustment under varying load conditions keeps filtering performance stable from light load to full load.
- Energy saving and equipment protection: Reduces power loss in transformers, cables and motors, and extends the service life of electrical equipment.
- Optimized mid-range capacity: 125A output fills the gap between modular systems and large cabinets for cost-effective solutions.
- IP54 high protection: Robust enclosure for dusty workshops, textile plants and coastal installations.
- Transformer and cable protection: Continuous filtering reduces overheating and extends the service life of distribution equipment.
