Product Description:

The 131B9826 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. It converts three-phase mains power into a variable-frequency output that allows controllers to adjust induction motor speed in conveyors, pumps, and other automated machinery. The unit delivers a continuous mechanical power rating of 15 HP, equivalent to 11 kW, so motors within that range can operate without derating.

This capacity suits midrange centrifugal fans, screw compressors, and material-handling belts that require stable torque across the available speed range. The drive is built for supply lines between 380–500 VAC and accepts three-phase power, allowing direct connection to standard industrial feeders. The chassis has an ingress protection rating of IP20 with a chassis enclosure, so the unit must be installed inside a protected electrical cabinet that prevents unintended contact and exposure to contaminants.

An integrated filter rated as RFI Class A1/B (C1) attenuates conducted electrical noise, allowing the drive to operate on public low-voltage networks without an external line filter. Setup and diagnostics are handled through the graphical local control panel, which presents parameter values and fault codes on a backlit display for convenient on-site access. Mechanical integration uses normal cabinet mounting for A, B, and C frames, allowing standard VLT mounting holes and airflow clearances to be used. The internal identifier 302 aligns the unit with compatible FC 302 fieldbus options and control accessories. This catalog number has no A, B, C, or D plug-in modules and does not include a brake chopper, while its printed circuit boards are uncoated. Control wiring enters through the terminal strip beside the relay outputs, maintaining clear separation from the power bus bars inside the cabinet.
