Product Description:

The FC-101P11KT4E20H4XXCXXXSXXXXAXBXCXXXXDX is an AC variable frequency drive built by Danfoss for the VLT FC 101 HVAC Basic Drives series. It is intended for building automation where fans, pumps, and other induction-motor loads need speed control instead of constant full-speed operation. By adjusting output frequency and voltage to match system demand, the drive helps air-handling units, chillers, and circulation pumps run only as fast as required by the control loop. It is commonly used where airflow or water flow changes throughout the day and steady motor control is needed without abrupt operation.

Continuous output capacity is rated at 11 kW, which corresponds to 15 HP. The power stage accepts 380 – 480 VAC input and is intended for three-phase power systems commonly used with commercial HVAC equipment. The enclosure is an IP20 / Chassis design, so the unit should be installed inside a cabinet or other protected electrical enclosure. This arrangement suits panel-mounted installations where surrounding equipment provides the necessary barrier against accidental contact with energized parts.

Power and control conductors enter through standard cable entries, which support orderly routing inside the enclosure. The drive has no brake chopper, so applications that need frequent rapid deceleration require external braking hardware instead of an internal braking circuit. A coated PCB helps protect the electronics from moisture and airborne contaminants that may be present in ventilation and mechanical-room environments. The built-in filter is rated as RFI class A1 (C2), which helps limit conducted interference returning to the input line. This combination supports fixed-speed replacement and variable-speed HVAC duty where compact panel installation and basic emission control are required.
