Product Description:

The FECP01.1-250K-3P400-A-BN-NNNN-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat within the FEC Frequency Converters series. It is intended for variable-speed operation of centrifugal pumps and ventilation fans in industrial or building automation systems. By altering the supply frequency delivered to an induction motor, the unit provides precise flow control and improves energy efficiency compared with traditional throttling methods. The converter installs in a standard control cabinet and communicates with supervisory controllers through its front keypad or optional network interfaces, integrating easily into existing process lines. This operating approach is useful where airflow or fluid delivery must be adjusted throughout the day without running the motor at full speed all the time.

The power section accepts a three-phase mains connection and tolerates an input range of AC 380 to 480 V, which places it in the 400 VAC voltage class and removes the need for external transformers in most facilities. Its enclosure carries an IP20 protection rating, meaning live parts are finger-safe when the panel door is closed. During brief load surges, the drive can deliver 120% for 60 seconds of rated current, which helps avoid nuisance trips when dampers snap open or pump head rises suddenly. Continuous service is supported by a durable heat sink layout, and the operator section does not include a potentiometer, so parameter entry is handled through digital controls.

For longer upsets, the converter supports 105% for 60 minutes, allowing extended operation while temporary system restrictions are addressed. All power electronics are arranged on a large-size mounting panel that increases thermal mass and simplifies cable routing in spacious MCC enclosures. The product is Design 1 in the first generation, which indicates its place within the series build sequence. The larger mounting area also leaves more room between power connections and control wiring inside the cabinet.
