Product Description:
The 131U3877 is an AC drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. As a member of the VLT AutomationDrive FC product group, it serves as a variable-frequency controller that regulates the speed and torque of three-phase motors used in automated production lines and process equipment. The enclosure is intended for normal cabinet mounting in A, B, and C frames, so the unit can be integrated alongside other control hardware in a standard control cabinet without special brackets or added ventilation accessories. It is suitable for conveyors, pumps, fans, and other motor-driven equipment that benefit from adjustable speed control.
The drive delivers a continuous output of 0.75 kW, which is equivalent to 1.0 HP, and draws supply power from 380–500 VAC. An integrated brake chopper enables rapid motor deceleration, while the built-in RFI filter limits conducted emissions on the supply lines. The chassis has an IP20 / Chassis rating, so it provides basic finger protection when mounted inside a panel. With a front width of 90.0 mm, the device occupies minimal horizontal space. A graphical local control panel is installed for parameter entry, standard cable entries simplify field wiring, and the printed circuit boards are uncoated. The front panel also gives direct access to operating data and menu navigation without separate external controls.
In physical terms, the enclosure measures 220.0 mm from front to back and 268.0 mm in height, allowing orderly stacking inside compact control cabinets. The power section is configured for three-phase power, which helps balance line currents and supports common industrial supply arrangements. Closed-loop feedback is supported through the optional MCB-103 Resolver Option, providing position data for applications that demand precise low-speed control. The base unit is supplied without A, C, C0, C1, D, or mains plug-in cards. This keeps the standard configuration focused on the core drive functions when no additional interface or expansion hardware is required.
