Product Description:

The 131X8033 is a decentralized frequency converter from Danfoss that belongs to the VLT FCD 302 Decentral Drives series. It mounts directly on the motor or nearby equipment and provides local speed control for three-phase induction motors in conveyors, mixers, and similar installations, removing the need for a separate control cabinet in distributed automation layouts. This placement keeps the drive close to the load and helps simplify machine layouts where centralized enclosure space is limited.

The drive supplies the motor with up to 0.55 kW of output power, which corresponds to 0.75 HP in mechanical terms. It accepts a three-phase supply of 380-480 VAC, so it can be wired into common industrial low-voltage grids without an autotransformer. A sealed IP66/NEMA4X housing allows washdown cleaning and blocks airborne dust, while the integrated RFI Class A1/C2 filter limits conducted emissions on the mains. There is no integrated brake, so applications that need rapid stopping must use an external mechanical system. The unit ships without brackets, an installation box, or plugs for mains, motor, or sensor connections, so cable glands can be selected to match site requirements. No display connector or switch option is present, which keeps the faceplate clear for hygienic environments.

Communication and auxiliary power features are organized through modular options. The A-slot is populated with Profibus DP for fieldbus control, while the B-slot remains empty because no B option is ordered. A dedicated 24 V DC backup input maintains control logic during mains outages, permitting an orderly stop. The product belongs to the VLT Series 302 and is classified in the VLT Decentral Drive FCD group. The lack of a fieldbus plug, sensor plugs, or a switch option simplifies sealing and reduces potential ingress points around the enclosure.
