Product Description:

The Danfoss 131B0968 belongs to the VLT FC 301 Automation Drives series and functions as an AC variable frequency drive for controlling induction motors in automated machinery. By modulating output frequency and voltage, the unit allows PLCs to match motor speed to process demand, improving energy use and reducing mechanical stress. It is intended for standard cabinet mounting and integrates into existing switchgear layouts without requiring an additional external enclosure. Its variable-speed control is suitable for applications such as pumps, fans, conveyors, and other motor-driven equipment that operates under changing process conditions.

The power stage accepts a mains supply of 380–480 VAC, and its three-phase power input connects directly to standard industrial feeders without phase conversion. At the output terminals, it delivers 2.2 kW of continuous electrical power, equivalent to 3.0 HP, allowing compatible motors to operate across an adjustable speed range. An integrated IP20 chassis enclosure protects internal electronics against accidental finger contact and solid objects larger than 12.5 mm. The drive must be installed inside a suitable control cabinet, with adequate airflow provided to control internal temperature. Electromagnetic interference is limited by the built-in RFI Class A1/B filter, which reduces conducted noise on the line and motor cables for general industrial use.

For applications that rely on external supervisory panels, the drive is supplied without an LCP, leaving the front interface available for a compatible keypad or remote display. Cable routing is supported by the standard gland plate entry pattern, which provides an organized path for mains, motor, and control wiring. The printed circuit assemblies are not coated, so the drive should be installed in an environment that remains within the permitted limits for moisture, dust, and corrosive gases. The configuration has no adaptation and does not include a brake chopper, so applications requiring dynamic braking must use suitable external equipment. It also omits the optional C1 filter and carries the Danfoss 301 series identifier. External mains filters or communication cards may be added when required by the application and supported by the drive configuration.
