Product Description:

The 131B2448 is an AC variable frequency drive produced by Danfoss and supplied under the VLT FC 301 Automation Drives series. Designed for cabinet installation, the module modulates the incoming mains power so industrial controllers can vary induction motor speed, torque, and direction according to real-time process demands. By replacing traditional mechanical dampers or gear changes, the drive provides electrically controlled motion for pumps, fans, and light material-handling equipment while reducing energy consumption and mechanical wear.

The drive is sized for fractional-kilowatt duties and delivers a continuous output of 0.25 kW at the motor shaft. It accepts line supplies from 200 to 240 VAC using three-phase power, making it compatible with low-voltage industrial networks. An internal brake chopper dissipates regenerated energy during rapid deceleration and supports controlled stopping. Mechanical installation follows a standard cabinet pattern using A, B, or C frames, and the circuit boards are conformally coated for protection against moisture and airborne contaminants. The electronics are enclosed in an IP20 chassis, which protects against accidental contact with internal electrical components while allowing cabinet ventilation. Conducted emissions are suppressed to RFI Class A1/B, reducing the need for an additional line filter in most suitable panel installations.

For field integration, the A-slot carries the DeviceNet MCA 104 interface, allowing cyclic, change-of-state, and explicit messaging from a DeviceNet master. Motion feedback enters through the B-slot because the drive is equipped with the MCB-102 Encoder Option, allowing incremental encoder pulses to improve speed-loop accuracy. Operators interact with the drive through the Graphical Local Control Panel, which provides plain-text parameter names and supports trend monitoring. Cable glands use a standard arrangement that simplifies the routing of power, motor, and control wiring inside the cabinet. The internal series identifier 301 associates the unit with the broader VLT AutomationDrive FC product group and its related control functions.
