Product Description:

The 131B2353 is a variable-frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed three-phase mains power into a regulated output that lets controllers vary motor speed and torque in conveyors, pumps, and general process equipment. By modulating output frequency, the unit supports precise, energy-efficient motion control in industrial automation systems where compact drives can be mounted close to the machine.

This drive accepts a three-phase supply ranging from 380–500 V AC and draws a continuous current of 9.9 A at the upper end of that range. At the same voltage, the inverter can deliver a continuous output of 11 A to the motor terminals while operating at an efficiency of 0.97; only 187 W is dissipated as heat under rated load. Output power is limited to 5.5 kW, matching the requirements of midsize production machinery. Harmonic and radio-frequency emissions are controlled by the integrated Class A1/B (C1) filter, so additional external suppression is often unnecessary. A graphical LCP 102 keypad provides local access to start, stop, and parameter functions. The design does not include a brake IGBT.

The size A5 enclosure is rated IP55, keeping dust and low-pressure water jets away from the electronics. For installations governed by North American requirements, the enclosure is recognized as Type 12. A Class 3C3 conformal coating shields the printed circuit boards from harsh airborne chemicals. The drive can withstand an overload of 160% for 1 minute without derating. During that interval, the inverter can supply up to 17.6 A, providing additional torque for acceleration or clearing jams. Internal cooling paths are sized to manage the calculated heat dissipation during operation.
