131B8674
The 131B8674 is a variable-frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series, where it provides speed control for three-phase motors in automated production lines, conveyors, and fluid-handling systems. By varying output frequency and voltage, the unit enables machines to match torque demand, reduce energy consumption, and protect mechanical components from abrupt starts or stops.
This drive supplies 75 kW of continuous mechanical power, equal to 100 HP, allowing it to govern large pumps, compressors, or extruders without derating. It accepts a mains window of 380 – 500 VAC and connects through standard cable entries for straightforward installation. The enclosure carries a IP54/Type12 N3R rating, so internal electronics are shielded against dust and splashing liquids. Integrated EMC suppression is handled by the RFI Class A1/B (C1) filter, keeping conducted emissions within industrial limits. Belonging to the VLT AutomationDrive FC product group, the unit ships with conformal PCB coating to improve service life in environments where humidity or airborne contaminants may be present.
No option cards are fitted and the design omits a brake chopper for safe-stop duties. The power stage is wired for Three Phase Power and is catalogued under series code 302. A conformal Coated printed-circuit board adds an extra barrier against moisture, while the operator interface is a Graphical Local Control Panel that provides parameter access and real-time feedback at the cabinet door.
