131F8418 by Danfoss

Produced by Danfoss, the 131F8418 belongs to the VLT FC 302 Automation Drives series within the VLT AutomationDrive FC product group. This three-phase AC drive is installed in control cabinets and regulates motor speed by adjusting supply frequency and voltage, supporting a wide range of factory and process automation tasks that demand flexible velocity profiles, torque limiting, and coordinated start-stop sequences. Its integrated brake circuitry supports controlled deceleration during speed changes.

Electrically, the unit operates from a three-phase input of 380 - 500 VAC and is sized for 16.6 kVA at 400 V. It delivers 24 A of output current between 380 and 440 V and 21 A when the mains is above 441 V. The integrated brake chopper handles braking energy during deceleration, and the RFI Class A1/B (C1) filter suppresses line emissions. No optional A, B, C, C0, C1, D, adaptation-B, or mains modules are installed, so the hardware remains standard. A coated PCB, standard cable entries, and the graphical Local Control Panel support installation and parameter editing without extra boards.

The drive is rated for 11 kW of continuous motor power, which is equivalent to 15 HP, while internal losses are held to 392 W under nominal load to limit cabinet heating. It carries an IP20 / Chassis protection rating, so live parts remain finger-safe while ventilation openings must stay inside an enclosure. The housing stands 399 mm high and is 249 mm deep, and it is delivered in frame size B3 for standard cabinet mounting. Standard three-phase bus bars connect to the built-in terminals, and the unit's brake chopper, coated boards, and Class A1/B filter share the same footprint. A standard set of cable entries and the absence of mains, software, or communication options simplify wiring because no auxiliary boards occupy the spare slots.
