Product Description:
The 131B3391 is an AC variable frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed-frequency mains power into a controlled output, allowing connected induction motors to operate at speeds that match changing demand in pumps, fans, conveyors, and other automated equipment. Designed for cabinet installation, the drive occupies the standard footprint for this platform and provides front access to operating controls and connection points. Its compact format helps preserve space for neighboring control and power components within an electrical enclosure.
The drive accepts three-phase power and has a rated motor output of 1.5 kW, which is equivalent to 2.0 HP. This output range supports small and medium motor applications that require adjustable speed, controlled acceleration, and repeatable operation. The IP20 chassis enclosure protects users from accidental contact with internal electrical parts while allowing airflow through the installed cabinet. Standard mounting provisions on A, B, and C frames secure the heat sink against the panel, helping transfer heat away from the power electronics. A built-in RFI filter reduces conducted electrical interference so the drive can operate near sensors and other sensitive control devices. Operating information is presented through the Numerical Local Control Panel, which displays speed, current, parameter values, and fault codes on a segmented screen. The detachable panel also provides direct menu access without requiring the enclosure to be opened.
During rapid deceleration, the integrated brake chopper directs regenerated energy to a suitable braking resistor for controlled dissipation. This function helps limit excessive DC-bus voltage when a connected motor returns energy to the drive. The unit uses coated printed circuit assemblies that resist condensation, fine dust, and airborne moisture while preserving electrical insulation. Standard cable entries provide organized paths for mains, motor, and control wiring through the chassis. The standard language pack supplies menu text for routine setup and operation, while the modular design allows compatible functions to be added through the available expansion slot when required by the application.
