Product Description:

The FECG01.2-15K0-3P400-A-BN-NNNN-01V01 frequency converter is manufactured by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. It is used in general automation to convert fixed-frequency, three-phase mains power into a controlled output for induction motors. This allows connected equipment to start smoothly, match process speed requirements, and reduce mechanical stress during routine operation.

This converter is rated for an apparent power of 21 kVA, so the supply must support that volt-ampere demand during full operation. Its drive section provides a continuous power rating of 15 kW, which is the maximum motor shaft power the unit can support without exceeding thermal limits. The permissible mains window is 3 AC 380 to 480 V, allowing the same model to operate on common industrial supplies in the 400 V class. Internally, the controller adjusts voltage with frequency and can modulate output up to 650 Hz. Because it operates in V/F mode, torque behavior follows the programmed voltage-to-frequency ratio instead of relying on sensor-based feedback.

For transient events, the inverter tolerates 200% for 1 second and 150% for 60 seconds of overcurrent, which helps it handle short acceleration periods and temporary load spikes without immediate tripping. An internal brake chopper dissipates regenerated energy during rapid deceleration, and the power stage supports a rated output current of 33 A with an input current of 42 A. The enclosure has an IP20 protection class, so the unit is intended for cabinet installation while remaining accessible from the front panel. Mechanical size 3 measures 392 mm high, 275 mm wide, and 218 mm deep, and the housing weighs 10.9 kg. Operation is permitted up to 90% relative humidity, and the converter comes without a built-in potentiometer.
