Product Description:
The FC-101P2K2 variable frequency drive is produced by Danfoss for the VLT FC 101 HVAC Basic Drives series. By adjusting the frequency and voltage applied to induction motors, the drive allows air-handling units, condensate pumps, and similar loads to match their output to actual demand. This control method reduces energy consumption and mechanical stress within automated heating, ventilation, and air conditioning systems.
The electrical section is rated for a continuous output of 2.2 kW, corresponding to 3.0 HP, and delivers a steady motor phase current of 5.3 A when installed below an altitude of 1000 m without derating. A true power factor of ≥0.9 keeps line current nearly in phase with voltage, allowing upstream protection devices to be sized accurately. Two analog inputs with 10-bit resolution accept temperature or differential-pressure signals, while two analog outputs with the same resolution report speed references or process feedback to a building management system. Four digital inputs enable start, stop, and fire-mode commands, while four digital outputs transmit operating states such as run, fault, and ready. The logic section also supports two relay outputs for interlocking external contactors that require isolated switching contacts.
Field wiring can be connected to terminals that accommodate conductors up to 4 mm² (10 AWG), and the drive supports motor cables as long as 50 m without additional output filters. The minimum temperature for full-load operation is 0 °C, which aligns with typical mechanical-room conditions. An internal 24 V DC supply provides up to 80 mA, allowing external transducers or pilot lights to be powered directly from the drive. The relay contacts can mirror solid-state signaling in applications that require electrical isolation, while the analog and digital channels support closed-loop HVAC control.
