Product Description:

The FECP01.2-110K-3P400-A-BN-MODB-01V01 is a frequency converter built by Bosch Rexroth Indramat within the FEC Frequency Converters series. Designed for pump and fan applications, the unit modulates the supply to standard three-phase motors so process flow can be matched to demand while reducing energy consumption in industrial automation. As a first-generation Design 2 device, it combines scalar control with field-proven hardware to deliver consistent speed regulation in HVAC and fluid-handling systems.

The converter operates on 3 AC 380 to 480 V line power and can support motor output up to 110 kW. A continuous output current of 223 A supports this power level, and the silicon-vector PWM stage maintains a digital resolution of 0.01 Hz so fine speed trimming is possible. Overload headroom is provided through a capacity of 120% for 60 seconds, allowing short process surges without tripping. For the startup of loaded centrifugal equipment, the device supplies 150% at 5 Hz torque to help overcome static friction before ramping to nominal frequency. These operating characteristics are used under V/F control mode, and an external brake chopper dissipates regenerated energy when high-inertia loads decelerate.

System integration is aided by 8 digital command inputs, three analog channels, and a Modbus interface for supervisory PLCs. Speed may be regulated across a ratio of 1:100, which suits fan curves and variable-head pump circuits. The housing carries a protection level of IP20, which shields internal circuitry while permitting cabinet mounting where airflow is available, and the overall mass of 96.5 kg is consistent with its size 7 frame. Enclosure dimensions of 850 mm in height, 570 mm in width, and 360 mm in depth fit the panel space required for this unit. Relay contacts are rated at 3 A, and the converter is intended for indoor industrial environments that require scalable speed control without a built-in potentiometer.
