Product Description:

The FC-101P4K0T4E5AH2XAXXXXSXXXXAXBXCXXXXDX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 101 HVAC Basic Drives series. It converts fixed-frequency mains power into a regulated motor output for building automation systems. This regulation allows fans and pumps to operate at speeds that match current heating, cooling, and ventilation demand. Reducing unnecessary motor speed can lower energy consumption while providing controlled airflow or fluid circulation in HVAC equipment.

The model accepts a nominal input of 380–480 VAC from a three-phase network. It provides a continuous motor output capacity of 4.0 kW (5.0 HP), making it suitable for compatible fan and pump motors. The cabinet-mounted enclosure has an IP54 ingress rating, which protects internal components against dust and incidental water spray in utility rooms. Power and control wiring pass through standard cable entries provided under Adaptation A, while Adaptation B adds no mechanical changes. The drive does not include a brake chopper, so controlled stopping relies on its programmed deceleration profile and the connected load. The A, B, and D option positions do not contain additional modules, and the C0 and C1 expansion slots are empty. Its printed circuit boards are not conformally coated, so the installation area should remain free of corrosive moisture and conductive contamination. The mains section does not include a dedicated harmonic reduction device or an integrated disconnect.

Electromagnetic interference is reduced by the built-in RFI filter, which helps limit conducted noise returning to the supply. Operator interaction is provided through an onboard alphanumeric local control panel that displays operating values, parameters, warnings, and alarms without requiring an external keypad. The interface supports direct entry of motor data, speed references, ramp times, and application settings from the front of the drive. A standard language pack provides multilingual menus for configuring the available control functions. Control logic is based on the VLT HVAC Drive platform and supports the normal operating functions required for variable-speed fan and pump applications. The absence of additional software and expansion modules keeps the control arrangement focused on the drive’s integrated HVAC functions.
