Product Description:

The FC-102P5K5T4P55H1UGXXXXSXXXXAX is a variable frequency drive manufactured by Danfoss within the VLT FC 102 HVAC Drives series. It regulates induction motor speed to match real-time airflow, pressure, and temperature demands in commercial and industrial buildings. By converting fixed-frequency mains power into a modulated output, the drive supports accurate motor control in air-handling units, chiller pumps, and boiler feed systems. Adjusting motor speed according to system demand can reduce unnecessary energy consumption while maintaining stable operation. The drive can also reduce mechanical stress associated with abrupt motor starts and frequent process changes.

The drive accepts a supply of 380–480 VAC and uses three-phase power, allowing direct connection to compatible commercial power systems. Its inverter section delivers 5.5 kW, which corresponds to 7.5 HP for medium-sized HVAC equipment. An IP55/Type 12 backplate enclosure protects the internal electronics against dust, incidental contact, and water jets. This enclosure supports wall or backplate mounting in locations where a separate sealed cabinet may not be necessary. The drive uses an A5 frame with a B and C backplate kit, providing a compact mechanical arrangement for the stated power range. Adaptation A supplies standard cable entry provisions for organized power, motor, and control wiring.

Electromagnetic interference is reduced by an integrated RFI Class A1/B (C1) filter, which helps limit conducted emissions on the connected power system. Controlled deceleration and safety functions are supported by an internal brake chopper with Safe Stop. Local configuration and operating data are available through the Graphical Local Control Panel, which presents status information and parameters in a readable format. A standard language pack provides multilingual menu text for supported operating regions. The printed circuit boards are uncoated, so the installation area should protect the drive from corrosive vapor, condensation, and conductive airborne contamination. The controller carries the series identifier 102, placing it within the control platform used for VLT FC 102 HVAC applications. Standard cable access, integrated filtering, and local controls support connection to common building automation and motor-control arrangements.
