Product Description:

The FECG01.2-3K70-3P400-A-SN-NNNN-01V01 is a variable-frequency power module manufactured by Bosch Rexroth Indramat for the FEC Frequency Converters series. Installed in general automation lines, it converts fixed three-phase input power into an adjustable output that lets conveyors, pumps, and material-handling drives match process speed. This type of control helps reduce abrupt starts and gives connected motors a speed range that can be matched to process demand. The compact module bolts into small control panels and integrates with Indramat drive networks for coordinated motion.

In electrical terms, the unit uses a 3-phase supply and remains stable on input voltages from 3 AC 380 to 480 V. Power devices are dimensioned for the 400 VAC class, so upstream fusing and cabling can follow standard sizing for this voltage range. For dynamic starts, the converter delivers 200 % for 1 second, and for heavier but longer ramps it allows 150 % for 60 seconds before the protective limit engages. These overload windows let machines clear static friction, restart loaded conveyors, or accelerate pump loads while keeping semiconductor temperatures within safe limits. Current sensors and internal control timers supervise each event and taper output after the permitted duration expires.

An IP20 construction offers basic touch protection but requires mounting inside a sealed cabinet whenever airborne dust or coolant is present. This model is classified as Design 2 of the 1st generation. Its high overload capacity is matched to a small panel size, which helps in installations where space is limited and short bursts of extra torque are needed. The absence of a potentiometer shifts all speed references to the host PLC, eliminating drift from manual knobs and keeping setup consistent across multiple axes and centralized control schemes.
