En el mundo digitalizado de hoy, Los centros de datos son la columna vertebral de la infraestructura de TI. Sin embargo, con el uso creciente de cargas no lineales como servidores, Sistemas UPS, 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. Conexiones eléctricas
Input/Output Wiring: Connect to the three-phase system as specified
Neutral and PE (Protective Earth): Always ground the unit for safety
Connecticut (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. Puesta en marcha & Configuración
Power On Sequence: Follow startup instructions step-by-step
System Configuration: Using the AHF’s touchscreen or software interface, input:
Relación CT
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, Éternet)
✅ 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
