Product Description:
The FC-102P45KT4E20H2 IN is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 102 HVAC Drives series. As a closed-loop speed controller, it modulates fan or pump motors to match real-time airflow or fluid demand in building automation systems, reducing energy drawn during partial-load operation and improving overall HVAC efficiency. It is commonly used on ventilators, cooling towers, and booster sets where stable motor control is needed as demand changes throughout the day. Its control profile also suits variable-torque applications that benefit from automatic response to changing system conditions.
This drive supplies motors with up to 60 HP of mechanical output while presenting an electrical service requirement of 380 – 480 VAC. At the inverter’s output bridge, power conversion is rated for 45 kW, allowing for switching losses and cooling overhead. The input section is designed for three-phase power, allowing balanced current draw from commercial distribution panels. The enclosure has an IP20 / Chassis rating, so the unit must be mounted inside a protective cabinet when installed in occupied spaces. Harmonic suppression is handled by an integrated RFI filter, reducing conducted noise that could interfere with nearby sensitive instrumentation or building management networks.
Mechanical integration is simplified by normal cabinet mounting slots that align with A, B, and C frame drilling patterns, allowing installation across multiple panel sizes without redrilling. The drive belongs to the VLT HVAC Drive product group and includes proportional-integral control macros together with automatic sleep functions for low-demand cycles. The internal designation 102 is used with accessory kits such as remote keypads and BACnet interface modules that share the same wiring conventions.
