Product Description:

The FECP01.2-110K-3P400-A-BN-NNNN-01V01 belongs to the FEC Frequency Converters series manufactured by Bosch Rexroth Indramat. As a frequency converter, it modulates AC supply frequency to control the speed of centrifugal pumps and axial fans in automated plants, matching motor output with changing process demands while staying within the electrical limits of its 400 V class. By varying output frequency and voltage, the converter helps pumps and fans respond smoothly to changing system pressure or airflow requirements. Operation is coordinated by first-generation FEC control electronics that detect phase imbalance on the 3-phase input and adjust carrier frequency to reduce harmonic injection.

This model operates on mains within 3 AC 380 to 480 V and is rated for 110 kW of continuous power, allowing it to drive large HVAC or process pumps without external step-up gearboxes. The input topology supports overloads up to 120% for 60 seconds to accommodate brief pressure surges or startup inertia. With a protection class of IP20, the ventilated enclosure protects against accidental finger contact with live components during cabinet installation. Its width is kept to 570 mm, which helps it fit standard cabinet frames while leaving room for airflow across the heat sink stack.

For longer transient events, the inverter sustains 105% for 60 minutes without derating, and regenerated energy is routed to an external brake chopper that helps prevent DC-bus overvoltage. The unit is delivered without an integral potentiometer, so parameter entry is handled through a keypad or fieldbus connection rather than a built-in control knob. It uses Design 2, with durability improvements focused on the IGBT modules and gate drivers. That layout suits pump and fan duty, where frequent cycling and airborne dust can place steady thermal demands on the power section.
