Product Description:

The 131B2840 drive is manufactured by Danfoss and belongs to the VLT FC 302 Automation Drives series. Within that platform, the unit fits the VLT AutomationDrive FC product group and serves as an adjustable-speed motor drive for industrial automation. It regulates motor torque and speed to match changing process demands in applications such as material handling, ventilation, and fluid circulation. Its design supports installation in control panels that use standard power distribution, motor wiring, and process-control connections.

The drive delivers a continuous mechanical output of 4.0 kW, equivalent to 5.0 HP, so it can operate medium-duty pumps, fans, or conveyors without requiring an unnecessarily large enclosure. The input section accepts a mains supply of 380–500 VAC from a three-phase power network. This voltage range covers common 400 V and 480 V bus systems used in industrial facilities. Internal DC-link energy can be routed to a brake chopper, which dissipates regenerated power during rapid deceleration and helps protect the intermediate circuit from excessive voltage. The assembly uses standard cable entries, allowing field wiring to follow typical gland-plate layouts. Adaptation slots A, B, C1, and D are unpopulated, leaving space available for compatible input, output, or communication cards if the application requires them.

For cabinet integration, the drive has an IP20 chassis protection level, which permits cooling airflow while helping prevent accidental finger contact with live internal parts. Radio-frequency emissions are limited by the integrated RFI Class A1/B (C1) filter, helping control panels meet applicable electromagnetic compatibility requirements without a separate filter assembly. The drive uses uncoated circuit boards, so it should be installed in a dry, clean environment with suitable protection from moisture and corrosive airborne contaminants. Its normal cabinet mounting for A, B, and C frames allows multiple FC 302 drives to be arranged on a shared backplate. Adequate spacing around the chassis supports ventilation and provides access to power, motor, and control terminals. The open chassis format is intended for installation inside a suitable electrical enclosure rather than direct exposure to the surrounding production area.
