Product Description:

The FECP01.2-75K0-3P400-A-BN-NNNN-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat within the FEC Frequency Converters series. Intended for pump and fan drives, it converts fixed-frequency three-phase mains power into a variable output that lets automation systems match motor speed to real-time flow or pressure targets while maintaining process efficiency. This operating method can reduce unnecessary motor loading during partial-demand conditions and supports smoother process control across changing workloads. It is suited to applications where flow and pressure requirements shift throughout the day.

This unit delivers 75 kW of rated motor power across a supply window of 3 AC 380 to 480 V at 50/60 Hz. The converter accepts three-phase input and produces an output from 0 to 300 Hz, with output voltage tracking the incoming line so that motor insulation stress remains stable. Magnetic Flux PWM modulation limits harmonic distortion, and the external brake chopper handles regenerated energy during rapid deceleration. The unit uses design 2 hardware, is built in mechanical size 6, and has a large front panel for field wiring. For transient events, the inverter can withstand 120% for 60 seconds above its thermal rating, providing additional margin during acceleration or brief overloads.

Longer duty surges are supported by a secondary headroom of 105% for 60 minutes, aided by an airflow path protected to IP20. A starting torque of 150% at 5 Hz helps pumps overcome static friction without mechanical jarring, and closed-loop speed regulation of 1:100 supports both slow-speed priming and full-speed service. Operation is specified up to 1,000 m elevation without derating, matching most plant mezzanine installations. The enclosure is 455 mm wide, so cabinet layouts must reserve that footprint. The unit does not include an external potentiometer because setpoints are generally supplied over the control bus.
