Product Description:

The FC-102P30KT4E55H3XN is an AC variable frequency drive built by Danfoss for the VLT FC 102 HVAC Drives series. This drive modulates motor speed in ventilation, chiller, and pump circuits so building automation systems can match air or water flow to actual demand and reduce unnecessary energy use. By integrating current, voltage, and thermal monitoring with configurable control logic, the unit can replace throttling dampers or valves and provide stable pressure or temperature regulation across diverse HVAC zones. It is suited for systems that operate under changing load conditions throughout the day. This approach also helps support smoother motor response during partial-load operation.

Electrical compatibility starts with a supply window of 380–480 VAC, allowing the drive to connect directly to common industrial power feeds without an autotransformer. Because the input uses three-phase power, it can deliver balanced output to induction motors and reduce torque ripple during operation. The inverter is rated at 30 kW, which corresponds to 40 HP. An enclosure rating of IP55 / Type 12 helps protect the internal electronics from dust and low-pressure water jets, allowing wall mounting in mechanical rooms where condensate or airborne particles may be present. The front interface provides access to status information and adjustable operating values during normal use.

To comply with electromagnetic limits in commercial buildings, the integrated filter meets RFI Class A1/B (C1) so the drive can reduce conducted interference on connected power lines. The unit is supplied without a brake chopper, so regenerated energy returns to the supply line rather than to an internal braking circuit. Operators use the Numerical Local Control Panel to review operating values, acknowledge messages, and adjust settings directly at the drive. The unit carries the series code 102. This arrangement keeps routine operation and monitoring available at the device without requiring a separate interface.
