今日のデジタル化された世界で, データセンターは、ITインフラストラクチャのバックボーンです. しかし, サーバーなどの非線形負荷の使用が増加すると, UPSシステム, and cooling systems, data centers are increasingly vulnerable to harmonic distortion and power quality issues. A reliable rack-mounted Active Harmonic Filter (AHF) is an efficient solution to ensure smooth operations, minimize power loss, and protect mission-critical equipment.
This article explains how to install a rack-mounted AHF module—like the Parallel Rack-Mounted AHF from CoEpower—in your data center safely and effectively.
Why Data Centers Need Rack-Mounted AHFs?
Rack-mounted AHFs are specifically engineered to integrate seamlessly into data center environments. They offer:
-Compact, space-saving design that fits standard server racks
-Real-time harmonic suppression for fluctuating loads
-Improved power factor and reduced THDi
-Easy parallel scalability for expanding infrastructure
CoEpower’s Parallel Rack-Mounted AHF is ideal for modular setups and critical power applications.
Step-by-Step Guide to Installing a Rack-Mounted AHF
✅ 1. Pre-Installation Checklist
Before installation, ensure the following:
Power system audit: Confirm harmonic levels and system compatibility
Rack compatibility: Verify the AHF module fits your rack (typically 19-inch standard)
Ventilation: Make sure there’s adequate airflow and cooling
Power ratings: Match AHF current capacity with your load requirements
Compliance: Ensure grounding and electrical codes are met
Tip: Refer to the user manual provided by COE Power for exact specifications and guidelines.
✅ 2. Mounting the AHF Module
Secure mounting rails: Attach sliding or fixed rails in the desired rack position
Lift with caution: Use two-person lift or rack-mounting tools to insert the AHF safely
Fasten firmly: Secure the module with screws or latches to prevent vibration or movement
✅ 3. Electrical Connections
Input/Output Wiring: Connect to the three-phase system as specified
Neutral and PE (Protective Earth): Always ground the unit for safety
CT (Current Transformer) Placement: Install CTs on the main supply line (preferably load side of AHF) and ensure proper polarity
Important: Incorrect CT orientation or placement can result in ineffective compensation.
✅ 4. Commissioning & Configuration
Power On Sequence: Follow startup instructions step-by-step
System Configuration: Using the AHF’s touchscreen or software interface, input:
CT ratio
Harmonic compensation mode (select automatic or manual)
Desired THDi limit or power factor target
Parallel Mode (if applicable): Connect multiple AHF units and configure parallel operation using communication ports (RS485, イーサネット)
✅ 5. Testing and Monitoring
Perform load tests: Gradually apply load and observe real-time harmonic suppression
Verify compensation: Use a power analyzer to confirm THDi reduction
Enable alarms: Set thresholds for overload, temperature, and communication faults
Remote Monitoring: Integrate into BMS or SCADA system if available
✅ 6. Maintenance Tips
Routine inspection: Check air filters, fan status, and terminals
Firmware updates: Keep software and firmware up to date via COE Power’s support portal
Service intervals: Follow the manufacturer’s recommended schedule for internal checks and cleaning
