Product Description:

The FECP02.1-11K0-3P400-A-BN-MODB-01V01 is a frequency converter built by Bosch Rexroth Indramat within the FEC Frequency Converters series. Designed for centrifugal pumps and axial fans in industrial automation, it varies the output frequency supplied to a three-phase motor so flow or air volume can be adjusted without throttling losses. By converting a fixed 400 V AC input into a controlled waveform, the unit supports energy-efficient speed control across a wide operating range.

The converter has a rated output of 11 kW and can draw up to 30 A from the mains. During continuous duty, the power section limits motor current to 24 A, and the IP20 housing protects against accidental contact with live parts while still allowing cabinet airflow. It accepts a three-phase supply in the 380 to 480 V AC range for the 400 V class and regulates motor voltage through V/F control with Magnetic Flux PWM modulation. A digital frequency resolution of 0.01 Hz allows fine speed trimming across the 1:100 regulation range. The internal brake chopper works with an external resistor to dissipate regenerative energy, and the combination of ModBus communication, second-generation electronics, Design 1 hardware, and the lack of a potentiometer favors parameter adjustment through software.

The unit is assigned Mechanical Size 2 and uses a large control panel within an enclosure that measures 220 mm wide, 218 mm deep, and 392 mm high. Despite those dimensions, it weighs only 10.7 kg. Short-term load demand is supported by a start-up torque of 150 % at 5 Hz and an overload capacity of 120 % for 60 seconds. The thermal design also supports 105% loading for 60 minutes during extended operation. Its silicon devices and bus capacitors are rated for a total apparent power of 18 kVA, which provides additional capacity for frequent starts and prolonged overload conditions.
