Product Description:

The FECP01.2-5K50-3P400-A-SP-NNNN-01V01 is produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. Serving as a frequency converter, it alters the output frequency supplied to induction motors so pump and fan systems can follow process demand in automated plants. This lets motor speed track fluid flow or air volume while helping reduce energy use and maintain stable control loops. That function is useful in ventilation and water-handling systems where full motor speed is not required at all times. The device is intended for cabinet installation and has a small form factor that simplifies integration beside contactors, circuit breakers, and other drive electronics.

Rated output is 5.5 kW, enabling the converter to power medium-capacity centrifugal equipment directly. The accepted supply span of 3 AC 380 to 480 V is taken from a 3-phase network that matches the device’s 400 VAC class. Within an enclosure, the unit meets the IP20 protection level, so live parts remain shielded while ventilation is still required. During transient events, it tolerates 120 % for 60 seconds, which helps cover short periods of increased demand such as rapid valve movement or damper indexing. Mechanical size 2 keeps the frame compact at 220 mm in width, and the small front panel helps preserve door space in crowded cabinets. A built-in potentiometer offers a local speed reference, and the converter is intended for repetitive start-stop duty.

The long-duration overload reserve of 105 % for 60 minutes supports continuous operation when system back-pressure rises over time. An internal brake chopper is already mounted, allowing direct connection of braking resistors for faster fan rundown without extra modules. This arrangement supports controlled deceleration when a rotating load needs to stop more quickly than a natural coast-down would allow. The unit uses Design 2 electronics and belongs to the 1st generation of this product line.
