Product Description:
The 131B1156 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. The unit belongs to the VLT AutomationDrive FC product group and modulates induction motor speed in conveyor lines, pumps, and material-handling stations. By rectifying the incoming three-phase mains power and reconstructing a pulse-width-modulated output, the drive allows automation controllers to match motor torque to real-time process demands while reducing mechanical wear and energy consumption.
The drive has a continuous output rating of 18.5 kW, giving the inverter enough electrical capacity for machines that need up to 25 HP of shaft power under nominal conditions. The input section accepts utility supplies from 380 to 500 VAC, covering the common 400 V and 480 V networks found in manufacturing plants. Internal rectifiers and IGBTs are designed for three-phase power, so no external phase conversion is required. The enclosure has an IP21 / Type 1 rating, permitting installation in dry indoor areas while providing basic protection against fingers and vertically dripping water. The drive does not include a brake chopper, so dynamic braking energy must be handled through motor losses or a suitable external braking arrangement.
Electromagnetic compliance is enhanced by the integrated RFI Class A1/B (C1) filter, which attenuates conducted noise on the mains lines to meet first-environment limits. User interaction is handled by the detachable Graphical Local Control Panel, which displays operating parameters and fault codes without requiring a separate programming device. Control wiring passes through a standard cable-entry pattern in the drive’s cable plate, supporting orderly routing within an installation. The circuit boards are uncoated, which avoids an additional thermal barrier but makes the unit unsuitable for areas containing corrosive aerosols or similar airborne contaminants. The drive is supplied without functional expansions, adaptation cards, or additional mains options, while its available slots can accommodate compatible plug-in modules if the application requirements change.
