Product Description:

The 131B0463 variable frequency drive is manufactured by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed-frequency plant power into a regulated output that allows industrial controllers to govern motor speed, torque, and acceleration profiles. By placing this drive between the mains supply and an AC induction motor, automation systems gain closed-loop control that matches conveyor, fan, or pump speed to real-time process demand while reducing energy consumption and mechanical stress.

The drive is rated for 1.1 kW of continuous output, which corresponds to 1.5 HP, so machines in the fractional-to-low-kilowatt range can be powered without oversizing. Input terminals accept a supply of 380 to 500 VAC, and the unit is designed for three-phase power, ensuring balanced current draw on industrial distribution networks. An enclosure rating of IP20 / chassis allows cabinet mounting where basic touch protection is sufficient and ambient dust is controlled. The integrated filter meets RFI Class A1/B (C1), limiting conducted emissions so neighboring instrumentation is less likely to experience electromagnetic interference.

Field integration features include the A-slot option card PROFIBUS DP V1 MCA 101 for high-speed network communication with PLCs and a graphical local control panel that provides parameter access and real-time readouts without external tools. Backup power for the panel and control logic is supplied by the D-slot module MCB-107 24 V DC backup, so drive status remains visible during brief mains interruptions. Standard cable entries simplify gland plate design, while the uncoated printed circuit board allows direct access during maintenance. No internal brake chopper is fitted, making the unit suitable for constant-torque loads that do not require regenerative braking.
