Product Description:
The 131B4207 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 102 HVAC Drives series. It converts a fixed-frequency electrical supply into a regulated output for controlling motor speed. This capability lets building management systems modulate fans and pumps in ventilation, chilled-water, and heating loops, improving energy efficiency and process stability in automated HVAC installations.
This drive operates with a supply voltage of 380–480 VAC and is designed for three-phase power, allowing direct connection to common industrial distribution networks without transformers. Its continuous mechanical output is rated at 1.1 kW, which is equivalent to 1.5 HP and is suitable for small to midsize air-handling units or booster pumps. The chassis has IP20 protection, so the drive must be installed inside a cabinet that provides suitable protection from moisture and airborne contaminants. An integrated EMC network meets RFI Class A1/B (C1), reducing conducted emissions on motor cables and supporting compliance in commercial buildings that contain sensitive instrumentation. Internal braking circuitry is omitted, so dynamic energy must be managed through motor losses or an external resistor when rapid deceleration is required. Adequate cabinet ventilation must also be provided to prevent excessive heat accumulation during continuous operation.
User interaction is provided by the graphical local control panel, which supports parameter editing, trend readouts, and local start-stop control without external tools. Physical integration is simplified by normal cabinet mounting for A, B, and C frames, which aligns the heat sink and conduit entry pattern with standard enclosure layouts. The control electronics use an uncoated printed circuit board, so the cabinet must maintain low humidity and limit exposure to dust, corrosive gases, and other airborne contaminants. Standard cable entries simplify power and control wiring within the enclosure. The drive has no additional mains filters or adaptation modules, which keeps its physical footprint compact while preserving the required electrical connections. Installation clearances should permit access to the control panel, terminals, and cable entries while maintaining unrestricted airflow around the heat sink.
