Product Description:

The 131N0206 is an AC variable frequency drive engineered by Danfoss for the VLT FC 101 HVAC Basic Drives series. Classified within the VLT HVAC Drive product group, it is installed in air-handling units, centrifugal pumps, and cooling towers to regulate motor speed in commercial buildings. By varying output frequency instead of relying on mechanical throttling, the unit supports precise airflow or water flow control and reduces the energy consumed by HVAC motors. Its variable-speed operation also allows connected equipment to respond smoothly to changing demand rather than repeatedly cycling motors on and off.

The inverter delivers a continuous output of 37 kW, which is equivalent to 50 HP, making it suitable for midsize fan sections and booster pumps. It accepts a supply of 380–480 VAC from a three-phase line, so it connects directly to common industrial power systems within that voltage range. The enclosure is rated IP54 but not Type 12, allowing wall mounting in areas exposed to dust or light spray without an additional cabinet. An internal RFI filter attenuates conducted emissions traveling toward the power grid. The drive does not include a brake chopper, so external energy dissipation is required when an application calls for rapid motor stopping.

Power and control conductors pass through standard cable entries, providing organized access for field wiring during installation. Electromagnetic compliance is supported by the built-in RFI Class A1/B (C1) filter, which reduces the need for external line-filtering devices. Parameter access is provided through the front-mounted alphanumeric local control panel, allowing operating values and drive settings to be viewed or adjusted at the unit. The interface includes a standard language pack for multilingual menu access. The printed circuit boards are not conformally coated, so the drive must remain in an environment compatible with its enclosure protection. Proper mounting clearance and suitable ambient conditions are necessary to support cooling and protect the internal electronics during continuous HVAC operation.
