Product Description:

The 134F0300 is a variable frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series. The device converts fixed-frequency, three-phase mains power into a controllable output waveform, allowing plant controllers to adjust motor speed according to changing process demands. Regulating the motor output can reduce unnecessary energy consumption and limit mechanical stress during acceleration, normal operation, and controlled deceleration. The drive is intended for continuous-duty industrial automation systems, including conveyors, pumps, fans, processing equipment, and other machinery that requires adjustable motor speed.

Rated output power reaches 110 kW, which corresponds to 150 HP for large industrial motor applications. The drive accepts an input supply range of 380–500 VAC from a three-phase power network, allowing direct connection to common industrial feeders within that voltage range. Its IP20 chassis enclosure provides protection against accidental finger contact with internal electrical parts when the unit is properly installed inside a control cabinet. The open chassis format requires the surrounding cabinet to provide the additional protection needed for the installation area. The model does not include a brake chopper, so applications with substantial regenerative energy may require an appropriate external braking arrangement or a motion profile that allows the connected load to dissipate that energy safely. The unit supports standard cabinet mounting on the applicable A, B, and C mechanical frames, helping maintain consistent alignment when several drives are installed in the same panel.

Control interaction is provided through a graphical local control panel that supports parameter entry, operating-data trends, status monitoring, and fault readouts at the cabinet door. Conducted electrical emissions are reduced by the integrated RFI filter, which helps limit radio-frequency interference transferred through connected power lines. The circuit boards have a protective coated finish that improves resistance to humidity and airborne contaminants encountered in industrial cabinets. Power and control wiring pass through standard cable entries that are compatible with metric gland plates, providing an orderly path for incoming and outgoing conductors. The standard connection arrangement also supports secure cable retention and separation of power wiring from sensitive control circuits inside the enclosure.
