Technical Specifications:
The PHF Harmonic Filter is designed to work with Danfoss VLT® Series drives. It operates with a rated voltage of 400V and a frequency of 50Hz, suitable for a voltage range of 380-415V. The system requires a THVD of less than 2% and a line voltage unbalance of less than 1%. The filter is designed for a symmetrical load of a converter with an uncontrolled B6 rectifier.

Performance and Efficiency:
The filter assumes IE2 motor efficiencies and inverter efficiency greater than 95%. It can handle an overrating capacity of 160% for 60 seconds once per hour. The efficiency is greater than 0.98, and noise levels are below 72db. The insulation class is H, with an insulation resistance greater than 100MΩ at 1000VDC.

Environmental and Physical Specifications:
The filter operates in ambient temperatures ranging from -25°C to +45°C, with a temperature rise of 40K. It uses AF type cooling and has a weight of 60.0 kg. The protection class is IP 20.

Standards and Compliance:
The filter complies with IEEE 519, EN 61000-2-2, EN 61000-2-4, IEC/EN 61000-3-2, IEC/EN 61000-3-4, and IEC/EN 61000-3-12 standards. It is important to observe the protection clause to ISO 16016.

Installation and Connections:
The electrical installation involves connecting L1, L2, L3 to the grid side and L1', L2', L3' to the VFD side. Terminals A1, B1, C1, A2, B2, C2 are short-circuited by default but can be adjusted for capacitor bypass to improve power factor when there is no load.

Notes:
Technical specifications are subject to change without notice, and general tolerances conform to DIN 7168-m. The specifications in the drawing are without obligation.
