Product Description:
The 131B4218 is an AC drive produced by Danfoss for the VLT FC 102 HVAC Drives series. It is used in building automation to modulate fan, pump, and compressor speeds so that air-handling and chilled-water systems can respond to real-time demand. By managing motor frequency rather than relying entirely on mechanical dampers or valves, the drive improves energy use and reduces wear on downstream equipment. This method also provides smoother acceleration and deceleration when operating conditions change throughout the day.
This model accepts a supply of 380–480 VAC from three-phase power, allowing direct connection to common low-voltage distribution panels. The chassis has an IP20 enclosure rating, so the drive must be installed inside a suitable cabinet when protection from particulate ingress or accidental contact is required. An integrated electromagnetic interference network meets RFI Class A1/B (C1), limiting conducted emissions on the mains without external filters in typical commercial environments. Local interaction is provided through a graphical local control panel that displays operating data and allows parameter changes without a computer. This interface gives operators direct access to status information, motor settings, and drive controls at the installation site.
Physical integration uses standard cable entries that align with gland plates in typical HVAC control cabinets, helping organize incoming power, motor, and control wiring. The unit has no brake chopper, so high-inertia loads must coast to a stop or rely on an appropriate external braking method when rapid stopping is required. The electronics use an uncoated printed circuit board, making a clean, dry mounting location important for preventing moisture-related faults and contamination. Mechanical installation uses standard cabinet mounting for A, B, and C frames, providing consistent bolt patterns across several frame sizes and power ratings in the series. Adequate cabinet ventilation and the required installation clearances should be maintained so heat can leave the chassis during continuous operation.
