Product Description:
The FC-102P75KT4P is a variable frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. It regulates the speed of three-phase induction motors in air-handling units, pumps, and chillers, allowing building automation systems to adjust airflow or fluid flow according to real-time demand. This variable-speed operation can reduce unnecessary motor output while maintaining the pressure, temperature, or ventilation levels required by the connected HVAC equipment.
The drive accepts a 380–480 VAC supply and is designed for three-phase power networks commonly used in commercial and industrial facilities. Its continuous power rating is 75 kW, and the power conversion efficiency reaches 98%. The remaining electrical losses produce 1,384 W of heat, which must be removed through suitable cabinet ventilation. When connected to a mains supply between 380 V and 439 V, the drive can draw up to 133 A. An electronic current limit of 110% protects the drive and connected motor against sustained overload conditions. The series identifier is 102, placing the model within the corresponding FC 102 platform and its supported control options.
The motor output is rated at 100 HP. Output current reaches 147 A with a supply between 380 V and 439 V, while operation between 440 V and 480 V provides an output current of 130 A. A built-in autotuning function improves motor control and supports accurate slip compensation after the required motor parameters are entered. Control connections include two analog input channels, one analog output, six digital inputs, and two pulse inputs for sensor signals, setpoints, and operating commands. The analog output can retransmit speed or torque information to a supervisory control system without requiring a separate signal converter. The drive also provides two relay outputs for signaling operating status, fan confirmation, or fault conditions directly to a building management controller. Dual form-C relay contacts support flexible switching arrangements, while the digital inputs can receive occupancy, fire mode, freeze protection, and equipment interlock commands.
