Product Description:

The FECP01.1-45K0-3P400-A-BN-NNNN-01V01 belongs to the FEC Frequency Converters series manufactured by Bosch Rexroth Indramat. It is a frequency converter intended for cabinet mounting in automated pump and fan stations, where it modulates motor speed to match real-time demand. By supplying variable frequency and voltage, the unit supports flow regulation and can reduce energy use in centrifugal-load applications. It is a first-generation, Design 1 model in this product line.

On the power side, the converter operates from 3-phase mains and supports input voltages of 3 AC 380 to 480 V, which fall within the 400 VAC voltage class. Within this range, it can deliver a rated output of 45 kW to the connected equipment. The IP20 housing is suited to closed control panels and helps protect internal parts from accidental contact. Its control terminals do not include a built-in potentiometer, so the speed reference must come from an external analog signal or a fieldbus source. Current and voltage functions are handled on a large panel assembly that simplifies connection of the motor, the incoming line, and the external brake chopper leads.

Short-term overload capability reaches 120% for 60 seconds, while extended overload tolerance is 105% for 60 minutes. These limits allow temporary load increases without immediate tripping under normal operating conditions. The external brake chopper dissipates regenerated energy to help keep the DC link stable during rapid deceleration of high-inertia fans. Mechanical size 5 hardware uses the series big-panel footprint and has a width of 364 mm, which provides space for busbars and control boards. The drive is built for high durability, which supports the continuous duty cycles common in pump and fan service, and it uses remote setpoints for speed control.
