Product Description:

The 131B0048 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed-frequency mains power into a variable-voltage, variable-frequency output so plant controllers can regulate induction motor speed on conveyors, pumps, and ventilation systems. By inserting closed-loop control between the mains supply and the motor, the unit lets the control system match energy use to process demand while maintaining stable torque in industrial automation applications.

Its rated motor output is 2.2 kW, which corresponds to a mechanical shaft capability of 3.0 HP. The rectifier accepts line voltages from 380 to 500 VAC and uses three-phase power, allowing the drive to connect directly to common 400 V industrial networks. This input arrangement supports balanced power delivery across the supply phases and provides the electrical capacity required for the rated motor load. During rapid deceleration, the integrated brake chopper diverts excess energy to an external resistor to prevent DC-bus overvoltage. The braking circuit allows connected machinery to slow more quickly than it could through natural losses alone, which is useful for applications with frequent stops or high-inertia loads.

The drive is supplied with a Graphical Local Control Panel that displays operating status, alarms, parameter values, and trend data on the front cover. Its housing is rated IP20 / Chassis, so installation inside a suitable control cabinet is required. The open chassis construction supports internal airflow while preserving access to the power and control terminals during installation. Conductors pass through standard cable entries, and the included language pack provides a multilingual interface for local operation. Electromagnetic compatibility is supported by a filter certified to RFI Class A1/B (C1), which suppresses conducted electrical noise on the incoming supply. The filter helps prevent drive switching frequencies from interfering with nearby equipment connected to the same electrical network. The printed circuit board is not coated, so the cabinet should protect the drive from condensation, excessive humidity, conductive dust, and corrosive airborne contaminants.
