Product Description:

Bosch Rexroth Indramat manufactures the FECP01.2-45K0-3P400-A-BN-NNNN-01V01 as part of the FEC Frequency Converters series. This frequency converter regulates the speed of three-phase asynchronous motors used in pump and fan applications within industrial automation. It belongs to the first generation of the platform and carries Design 2, which identifies its product revision within the series. By converting fixed mains frequency to a controlled output, the unit permits energy-efficient flow and pressure adjustment without mechanical throttling. This control method helps the connected motor track changing process demand more smoothly during variable-load operation.

The converter delivers 45 kW of continuous shaft power when supplied from a 400 VAC line. Its power section accommodates a voltage window of 3 AC 380 to 480 V, allowing operation on common industrial grids without tap changes. A 3-phase input rectifier balances line currents and feeds the DC link so harmonic loading remains evenly distributed across the supply. During short-term transients, the drive tolerates an overload of 120% for 60 seconds, which supports motor acceleration and brief process surges without immediate derating. This short-duration reserve is useful when the application must respond to temporary changes in system pressure or airflow.

In continuous heavy-duty service, the unit can sustain 105% for 60 minutes, giving added margin during long operating periods with elevated demand. The housing carries an IP20 protection class, so it is intended for installation inside an enclosed control cabinet rather than in open plant areas. Overall width is 364 mm, and the enclosure is the big-size version that matches mechanical size 5. Dynamic braking energy is dissipated through an external brake chopper, which reduces heat inside the converter enclosure. The control board is supplied without a potentiometer, so speed reference entry is handled through external control signals instead of a built-in manual adjustment.
