Product Description:

The FECP01.2-37K0-3P400-A-BN-MODB-01V01 belongs to the FEC Frequency Converters series produced by Bosch Rexroth Indramat. It is a three-phase frequency converter that adjusts motor speed for pump and fan duties in process and HVAC installations. By altering the fundamental frequency sent to an asynchronous motor, the converter matches flow or air volume to demand while helping reduce energy use. This type of control is useful where process conditions change during normal operation. Generation 1 hardware and Design 2 packaging place this model in an early version of the product line.

A rated output of 37 kW is available for a connected motor without derating. A continuous current capability of 75 A supports that output on a 400 VAC mains supply. When short process peaks occur, the inverter tolerates 120% for 60 seconds before protective limiting engages. Output frequency can be adjusted from 0 up to 650 Hz with a digital resolution of 0.01 Hz, allowing fine speed changes under V/F control. Pulse patterns switch at 8 kHz using magnetic flux PWM to help reduce motor acoustic noise. The converter accepts a three-phase input, fits size 4 frames, and has a housing width of 290 mm with an integrated Modbus interface.

Additional operating allowances broaden the usable range. The second overload tier permits 105% for 60 minutes, supporting extended but moderate process surges, and startup torque reaches 150% at 5 Hz for heavy loads. An external brake chopper can be connected when dynamic stopping is required, and DC injection is available up to 60 Hz for as long as 10 seconds. The enclosure has an IP20 rating, and full power is available up to 1000 m altitude. The supply range of 3 AC 380 to 480 V matches the 400 VAC class, and the built-in Modbus command set supports a 1:100 speed regulation range without a potentiometer.
