Product Description:

The 131L7478 variable frequency drive is manufactured by Danfoss within the VLT FC 302 Automation Drives series. It converts fixed mains power into a regulated output for motor speed control in conveyors, mixers, and other three-phase loads. That control helps process and material-handling equipment maintain efficient, repeatable motion across changing operating conditions.

It accepts an input of 380 to 500 VAC and operates on three-phase power, which matches common industrial supply systems. A continuous output rating of 37 kW, equivalent to 50 HP, supports medium-sized pumps, compressors, and fans under normal duty. A built-in RFI filter reduces conducted emissions, while the standard language pack, uncoated PCBs, and current software release support straightforward integration.

Network communication is provided by the PROFIBUS DP V1 MCA 101 option card, allowing fast exchange of commands and status data with PLC systems. The integrated brake chopper manages regenerative energy during deceleration, which is useful in applications with frequent stopping. For feedback expansion, the MCB-103 Resolver Option can add resolver input capability. The IP20 / Chassis enclosure is intended for use inside a protected control cabinet.
