Product Description:

Bosch Rexroth Indramat’s FECP01.2-37K0-3P400-A-BN-NNNN-01V01 belongs to the FEC Frequency Converters series. As a frequency converter, it modulates the supply frequency delivered to induction motors so automated pump and fan systems can vary speed in response to process demand. The unit supplements programmable logic controllers by generating the variable-frequency, variable-voltage output required for energy-efficient flow or air-handling tasks on the plant floor. This control method lets connected motors follow changing load requirements without operating at full speed all the time.

This converter accepts a three-phase input in the 3 AC 380 to 480 V range that matches the 400 VAC class, allowing direct connection to common industrial mains. Its continuous rating of 37 kW supports medium-power centrifugal pumps and axial fans while remaining in an IP20 enclosure, so it must be installed inside a larger cabinet. For short overload events, it can deliver 120% for 60 seconds, which helps bring heavy rotating loads up to speed or recover from temporary process resistance. Its mechanical size 4 housing and a width of 290 mm provide clear terminal spacing for cable installation and support heat dissipation.

The brake chopper is External, so braking energy can be handled by a separately mounted resistor matched to the application. This arrangement supports applications that need braking hardware selected for the inertia of the driven system rather than a fixed internal option. Control electronics follow Design 2 of the series and are part of the 1st generation. Long-term load swings are accommodated by the second overload band of 105% for 60 minutes, which supports extended periods of near-peak demand. Setpoint entry is handled through control interfaces because the unit does not include an onboard potentiometer.
