Product Description:

The FECP01.2-7K50-3P400-A-SP-NNNN-01V01 frequency converter is built by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. It is installed between the incoming power supply and an asynchronous motor to adjust operating speed for pumps and fans, enabling energy-matched flow control in HVAC and process circuits. By adjusting output frequency through its integrated potentiometer, the unit supports variable-torque loads without an external speed reference. This allows airflow or liquid flow to follow demand more closely than fixed-speed operation. An internal brake chopper handles regenerated energy during rapid deceleration, reducing the need for external braking hardware.

On the electrical side, the converter is rated for 7.5 kW continuous output and accepts an input voltage of 3 AC 380 to 480 V. A 3-phase connection feeds the power stage, and the 400 VAC class suits common plant distribution networks. Short-term overload handling reaches 120 % for 60 seconds, while extended thermal tolerance allows 105 % for 60 minutes. These margins let the drive ride through startup surges and modest process upsets without tripping. Because fan and pump loads often vary with speed, adjustable frequency control can reduce unnecessary power draw during partial-load operation. The internal brake chopper quickly dissipates excess DC-bus energy, and the front-mounted potentiometer permits manual frequency trimming when a fieldbus is not present.

The enclosure width is 220 mm, which helps conserve rail space in densely packed cabinets. Its compact format suits small control panels where wiring space and airflow clearance are limited. A protection rating of IP20 guards against finger contact with live parts, so the converter should be mounted inside a closed electrical cabinet. The unit is Design 2, indicating its design revision within the FEC platform. The converter is built for high durability in continuous-duty pumping and ventilation equipment.
