Product Description:

The 131B0052 is a variable-frequency drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed three-phase input power into a modulated output that allows controllers to vary induction motor speed and torque on conveyors, pumps, and other machinery. Mounted inside a cabinet, the unit serves as the power interface between the mains supply and the motor while supporting both local keypad operation and remote network commands in industrial automation.

The drive accepts supply voltages from 380–500 VAC and operates with three-phase power, eliminating the need for phase conversion equipment. The inverter delivers up to 7.5 kW of continuous output, and its thermal design keeps semiconductor temperatures within safe limits at this load. The IP20 chassis enclosure provides protection against finger contact but does not seal the unit against dust or moisture, so installation inside a suitable control panel is required. Conducted emissions are suppressed by the integrated RFI Class A1/B (C1) filter, helping the installation comply with applicable electromagnetic compatibility limits. Standard cable entries simplify gland plate preparation and cable routing inside the enclosure. The cabinet-mounting arrangement accommodates the mechanical configuration used by the drive without requiring a separate floor-standing enclosure.

User interaction is handled through a graphical local control panel that displays parameters, operating trends, and alarms on a backlit screen. Its menu structure supports direct entry of motor data and adjustment of operating commands from the front of the cabinet. The electrical capacity corresponds to 10 HP for facilities that express motor power in horsepower. Rapid deceleration is managed by an internal brake chopper that diverts regenerated energy to an external braking resistor. The drive has uncoated printed circuit boards, so it must be protected from corrosive gases, condensation, and other contaminants that could damage exposed electronic components. A standard language pack is preinstalled to provide accessible menu text during setup and routine operation.
