Product Description:

The FECP01.1-90K0-3P400-A-BN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat within the FEC Frequency Converters series. It is intended for pump and fan applications, where variable motor speed improves process control and reduces energy use in HVAC and fluid-handling systems. By adjusting output frequency, the unit lets an induction motor follow changing load demands so flow or air volume can be controlled without relying on mechanical throttling. This operating method can help reduce mechanical stress on connected equipment during normal speed changes.

The converter accepts a 3-phase supply in the 400 VAC class and operates across an input range of 3 AC 380 to 480 V, making it suitable for common industrial power systems. Its nominal output is 90 kW, which suits medium and large centrifugal loads. With a protection rating of IP20, the unit is intended for installation inside a protected control cabinet rather than for direct exposure to dust or water. The unit uses mechanical size 6 and a large panel format to support heat dissipation and internal spacing for power components. The platform is generation 1 with design version 1, and it does not include a potentiometer, so speed reference signals must come from an external control source.

During overload conditions, the drive can deliver 120% for 60 seconds and sustain 105% for 60 minutes, which helps the system manage temporary demand increases without an immediate shutdown. An external brake chopper connection is available to dissipate regenerated energy during deceleration of loads with significant inertia. The enclosure width is 455 mm, so cabinet planning must allow space for cable routing, airflow, and service access. High durability is the primary performance characteristic, supported by reinforced power stages, conformal-coated control boards, and a thermal model tuned for pump and fan duty. These features support stable operation in applications that run for long periods at varying speeds.
