Product Description:
The FC-102P45KT4E55H1X is a variable frequency drive built by Danfoss and supplied under the VLT FC 102 HVAC Drives series. The unit converts fixed-frequency three-phase mains power into a modulated output that allows building automation controllers to regulate fan and pump speeds for heating, ventilation, and air conditioning processes. By adjusting motor frequency instead of throttling dampers or valves, the drive helps maintain airflow, temperature, and static pressure targets while reducing electrical consumption and mechanical stress in large commercial plants.
Its continuous output power is rated at 45 kW, which is the electrical power the inverter can supply to a connected induction motor at full load. This rating corresponds to a mechanical output of 60 HP. The input section accepts a supply range of 380 – 480 VAC, allowing direct connection to common low-voltage distribution boards. The drive uses three-phase power, so its rectifier receives balanced currents for steady operation across the supported voltage range. The enclosure has an IP55 / Type 12 protection rating, which protects the internal electronics against dust ingress and water jets commonly encountered in plant rooms or rooftop installations.
Electromagnetic compliance is supported by an integrated RFI Class A1/B (C1) filter, which attenuates high-frequency noise on the mains and motor lines. The absence of a brake chopper means that regenerative energy from an overrunning fan must be managed by the motor system or compatible external braking equipment. The VLT HVAC Drive configuration provides proportional-integral control and flow compensation functions intended for air-handling applications. These functions allow the drive to respond to process signals from pressure, temperature, and flow sensors without requiring a separate controller for every basic regulation task. The numeric code 102 corresponds to the control platform, keypad organization, and parameter structure used by this drive series.
