Product Description:

The FECP01.1-280K-3P400-A-BN-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. As a variable-speed drive, it modulates the output frequency supplied to induction motors so that pumps or fans can run only as fast as the process demands. By matching motor speed to load, the unit helps cut energy consumption, lower mechanical stress, and integrate easily into automated HVAC, water treatment, and general plant utility systems. This supports quieter operation and longer service intervals.

It is intended for connection to a 3-phase supply, a topology that balances line currents and allows the converter to feed symmetrical voltage to three-phase motors without added filters. The voltage class is rated at 400 VAC, and within that category the device tolerates input swings across the full 3 AC 380 to 480 V range, making it compatible with common low-voltage industrial networks. During short acceleration or deceleration peaks, the drive can deliver up to 120% for 60 seconds of its nominal current, which helps prevent nuisance trips when pumps start under head pressure. Its housing carries an IP20 protection class, so live parts are guarded against finger contact, but the unit must be mounted inside a closed electrical cabinet.

The continuous overload limit of 105% for 60 minutes allows sustained operation when process demand remains slightly above nominal, which is useful in systems that see seasonal peaks. Hardware marked as Design 1 belongs to the controller's initial hardware iteration, and the unit is part of the 1st generation of FEC drives. The converter uses a panel in the Big size format, which provides wider bus bars and a larger heat sink area to support the high durability rating. Because it is supplied without a potentiometer, speed references must be set through digital controls, which suits modern PLC-based pump and fan installations.
