Product Description:
The 131L9864 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 101 HVAC Basic Drives series. It regulates motor speed to match changing demand in building ventilation and pumping systems. By adjusting output frequency and voltage, the drive helps maintain air or water flow set points without requiring the connected motor to operate continuously at full speed. This control method can reduce energy use in fans, pumps, and other variable-torque HVAC equipment.
The drive supplies a continuous output of 2.2 kW, equivalent to 3.0 HP, allowing compatible motors to start and operate without an external soft starter. It accepts a mains supply of 380–480 VAC from industrial three-phase feeders and converts the incoming power into a variable-frequency, variable-voltage output. The IP20 chassis is intended for installation inside a ventilated electrical enclosure that provides the required protection against contact and contaminants. Standard cable entries provide access for mains, motor, and control wiring without additional mechanical adaptation kits. The drive has no brake chopper, so a braking resistor cannot be connected directly to an internal braking circuit. Its basic configuration omits additional communications, feedback, and mains options that are not required for conventional HVAC speed control.
The integral filter is rated RFI class A1 (C2) to reduce conducted electromagnetic interference in commercial and industrial installations. The unit uses coated printed circuit boards that resist moisture and airborne dust commonly present in mechanical rooms and air-handling areas. The configuration includes no local control panel, so operating adjustments are made through remote software or a compatible pluggable keypad. Built-in HVAC control functions support pump sleep operation, flow compensation, and proportional-pressure regulation for systems with changing demand. Remote control capability also allows the drive to receive speed references and operating commands from an external building controller while returning relevant status and diagnostic information. Proper enclosure ventilation remains necessary to remove operating heat and maintain reliable performance under continuous load.
