Product Description:

The FC-101P3K7T2E20H4XXCXXXSXXXXAXBXCXXXXDX is a compact AC variable frequency drive manufactured by Danfoss for the VLT FC 101 HVAC Basic Drives series. In ventilation, air-handling, and hydronic pumping systems, it converts fixed-frequency mains power into a pulse-width-modulated output that allows control systems to vary motor speed in response to temperature, pressure, or flow feedback. Matching motor speed to current demand can reduce unnecessary energy consumption while maintaining stable operation in building automation applications. The drive can regulate fans and pumps without relying on mechanical throttling as the primary method of controlling airflow or fluid flow.

Electrical integration centers on an input supply of 200–240 VAC. The converter draws power from a three-phase feeder, providing a balanced connection to the incoming supply. Its enclosure has an IP20 chassis rating, so live parts are protected against accidental contact, but the unit must be installed inside a suitable control panel. Conducted emissions are reduced by an internal RFI Class A1 (C2) filter that supports compliance with applicable electromagnetic compatibility limits for commercial environments. A coated printed circuit board helps protect the control electronics from humidity and airborne contaminants in plant rooms. Field wiring passes through standard cable entries that accommodate common panel-routing arrangements. The drive does not include a brake chopper, so motor deceleration must be configured to prevent excessive voltage on the DC bus.

The drive includes the latest release of standard software and a standard language pack for its available configuration tools. It is supplied with no local control panel, so parameter adjustments and operating commands must be handled through compatible external controls, PC-based tools, or a building management network. This arrangement supports installations in which the drive is mounted inside a panel and routine commands originate from a centralized automation system. The unit belongs to the VLT HVAC Drive group and is intended for variable-torque loads commonly found in heating, ventilation, and air-conditioning systems. Its control functions allow connected equipment to respond to changing process demand while reducing the need for continuous full-speed motor operation.
