Product Description:

The FECP01.2-19K0-3P400-A-BN-NNNN-01V01 frequency converter is produced by Bosch Rexroth Indramat as part of the FEC Frequency Converters series. It is a first-generation unit intended for pump and fan duty, where variable speed control improves process efficiency and reduces mechanical stress on connected equipment. By modulating motor supply frequency, the drive adjusts output speed without complex gearing, making it a compact option for industrial ventilation and fluid-handling stations. This operating method is well suited to systems that benefit from smooth speed changes and steady continuous operation.

The converter has an IP20 protection class, so it must be installed inside a cabinet that shields it from dust and accidental contact. Its voltage class is 400 VAC, and the input terminals accept a supply range of 3 AC 380 to 480 V. Because the power stage is built for three-phase lines, current is distributed evenly across the supply conductors during normal operation. The wide input range supports use on common industrial mains, and during short acceleration periods it can tolerate an overload of 120% for 60 seconds, which helps the connected motor overcome starting inertia without an immediate fault response.

For longer demand peaks, the converter can sustain 105% for 60 minutes, which supports ventilation cycles that remain slightly above nominal load for extended periods. The enclosure uses a large size format that provides additional space for bus bars, protective devices, and field wiring inside the unit. Mechanical reliability is supported by its high durability design, which suits round-the-clock HVAC operation. The converter is supplied without a potentiometer, so speed reference must be provided through external control signals rather than a front-mounted adjustment knob, which fits systems that use remote setpoint control.
