Product Description:

The FECP01.1-75K0-3P660-A-RN-NNNN-01V01 is a frequency converter manufactured by Bosch Rexroth Indramat and supplied within the FEC Frequency Converters series. In automated pump and fan stations, the unit adjusts the supply frequency so that induction motors run at the speed required for flow or pressure control. By replacing throttle valves or dampers with electronic speed regulation, it helps reduce energy consumption and mechanical wear while maintaining stable process variables in HVAC, water distribution, and general-purpose ventilation systems. This operating method also supports smoother motor control during changing demand conditions without relying on constant full-speed operation.

This converter accepts a 3-phase mains supply and delivers a continuous output of 75 kW, allowing medium-sized centrifugal machines to operate at rated duty without derating. Short-term overload tolerance reaches 120 % for 60 seconds, while extended loading is permissible at 105 % for 60 minutes before thermal safeguards intervene. These overload levels suit applications where demand can rise briefly during startup, pressure correction, or temporary process variation. An enclosure rating of IP20 keeps live parts finger-safe, but the unit still requires cabinet installation to protect it from dust and moisture in the surrounding area.

The mechanical housing is classified as size 6, and its front width of 455 mm helps with cabinet spacing beside adjacent control gear. As a 1st generation device identified as Design 1, it belongs to the early release of the platform. Dynamic braking energy is routed to an external chopper resistor, so the installation requires a matched dissipation path when frequent stops are expected. The platform uses durable construction and does not include a potentiometer, which helps prevent unintended local adjustment. Its pump-and-fan operating profile is intended for variable-torque loads where airflow or liquid movement changes over the course of normal operation.
