Apa itu filter harmonik aktif (Ahf)?
Filter harmonik aktif (Ahf) uses IGBT-based inverters and real-time DSP/FFT algorithms to inject inverse-phase currents, reducing current harmonic distortion (Thdi) to under 5%. These filters also balance reactive power and phase imbalance, offering dynamic improvements in power quality
Key features across CoEpower’s AHF lineup include:
-Fast response (<10 ms)
-Filtering harmonics from 3rd to 51st order
-Efficiency ≥ 97%, thermal loss ≤ 3%
-IEC 61000/62477 compliance and support for Modbus/Ethernet
Rack‑Mounted AHF Module
CoEpower’s Parallel Rack-Mounted AHF Module is designed for integration into standard racks or control cabinets. Each module handles 30A–150A and can be combined for up to 750A per cabinet
Highlights:
Modular & Scalable: Stack modules to expand capacity seamlessly.
Centralized Control: 7″ LCD controller for unified monitoring and configuration.
Optimized Space Usage: Ideal for control rooms, data center racks, or large switchgear.
Ideal Use Cases: Pusat data, industrial control rooms, automation cabinets, and large energy systems needing high-capacity, flexible harmonic compensation.
Wall‑Mounted AHF Unit
The Wall‑Mounted AHF is a compact modular unit ranging from 30A to 150A per module and supports unlimited parallel deployment (including optional floor cabinets)
Highlights:
Flexible Installation: Direct wall-mounted saves rack or floor space.
Space-Efficient: Perfect for wall spaces in offices, commercial facilities, or local substations.
Fast & Easy Deployment: Plug-and-play installation without disrupting existing panels.
Ideal Use Cases: Small-to-medium production units, office/server rooms, localized installations in commercial buildings, rumah sakit, EV chargers, and microgrids.
Rack vs Wall AHF: Side-by-Side Comparison
| Feature | Rack‑Mounted AHF | Wall‑Mounted AHF |
|---|---|---|
| Instalasi | Module inserted in rack/cabinet | Mounted directly on wall or in floor cabinet |
| Kapasitas & Skalabilitas | 30A–150A/module, expand to ~750A | 30A–150A/module, parallel installation available |
| Space Utilization | Rack-space within control panels | Frees up racks; uses wall real estate |
| Control & Monitoring | Centralized 7″ controller per cabinet | Local monitoring; network communication via Modbus/Ethernet |
| Maintenance & Access | In-rack access—requires rack access | Wall-level access—convenient maintenance |
| Best Suited For | Pusat data, industrial control systems, scalable installations | Offices, small plants, distributed installations |
Choosing the Right AHF for Your Facility
1, Assess Capacity Needs
Minor harmonic issues (≤150A) → Wall‑Mounted
High-density demand (≥300A) → Rack-Mounted
2, Space Availability
Rack space free? → Go rack-mounted
No rack space or distributed loads? → Choose wall-mounted
3, Control Preferences
Want centralized interface? → Rack-mounted system preferred
Localized units suffice? → Wall-mounted suits well
4, Scalability Needs
Anticipating future expansion → Rack modules scale easily
Fixed capacity needs → Wall-mounted is ideal
Sebagai kesimpulan, for large, centralized installations requiring scalable, high-capacity harmonic mitigation, Rack‑Mounted Active Harmonic Filters from CoEpower are the ideal solution. Sementara itu, Wall‑Mounted AHFs offer compact, flexible, and cost-effective performance for localized installations.
Next Steps:
-Evaluate your system’s harmonic levels (Thdi, load size)
-Choose the right form factor based on space and expansion plans
