Product Description:

The 131L4647 is an AC drive produced by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed-frequency line power to a variable output that lets automation controllers regulate motor speed in conveyors, pumps, or material-handling stations. Intended for normal cabinet installation on A, B, and C frames, the unit uses the series’ standard cable entries so field wiring can follow the same routing practices used on other VLT controllers. This arrangement helps the drive fit into common industrial control layouts without requiring unusual mounting or cable-routing changes.

The drive supplies a continuous mechanical capacity of 22 kW, which corresponds to 30 HP and fits mid-range industrial actuators. It tolerates input grids from 380–500 VAC without manual reconnection, maintaining constant torque across that window. Operation is limited to three-phase power, which supports balanced loading of the input rectifier and helps reduce harmonic stress. For assemblies mounted behind a control-cabinet door, the converter carries an IP20 / Chassis rating that helps protect against contact with live parts while still allowing airflow through the heat sink. Because no adaptation or mains options are fitted, all factory terminals and jumpers remain in their baseline configuration. That layout keeps the electrical arrangement simple and leaves the standard control and power interfaces in place.

Fast deceleration cycles are supported by the integrated brake chopper, which channels regenerated energy into an external resistor instead of the DC bus. Conducted and radiated emissions are reduced by the built-in RFI filter, helping the drive operate more cleanly in cabinets with other electronic equipment. A coated printed circuit board shields solder joints against moisture and airborne contaminants, which is useful in demanding environments. Local setup is handled through the front-mounted Graphical Local Control Panel, where operators can view parameters, trend data, and alarms without connecting a PC. Resolver feedback can be added later through the MCB-103 option card, giving the drive added flexibility for closed-loop motion applications that need that signal type.
