Product Description:

The FECP01.1-185K-3P400-A-BN-NNNN-01V01 frequency converter is manufactured by Bosch Rexroth Indramat and belongs to the FEC Frequency Converters series. Installed inside motor control centers, it modulates the output frequency and voltage delivered to centrifugal pumps or axial fans so their speed can follow process demand. This regulation promotes energy-efficient flow control while reducing unnecessary start-stop cycles on connected mechanical equipment. A large panel format supports wiring access in spacious cabinets, and the unit is intended for pump and fan automation where variable-speed operation is required.

The device is engineered for a three-phase supply. It accepts a line voltage of 3 AC 380 to 480 V and falls within the 400 VAC voltage class, allowing direct connection to standard plant power without a step-down transformer. The enclosure has an IP20 rating, so it must be installed in a protected cabinet or electrical room to prevent contact with live parts. Short-term overload capability reaches 120% for 60 seconds, giving the drive additional capacity during startup or during brief pressure increases in pump and fan service. The large panel size also supports heat dissipation, and the listed high-durability characteristic indicates suitability for continuous-duty operation.

For extended load surges, the converter can sustain 105% for 60 minutes, which supports processes that experience moderate but lasting flow increases. The drive uses Design 1 from the 1st generation. Operator adjustment by knob is not available because the unit is supplied without a potentiometer; parameter changes are made through the digital interface or by an external controller. This arrangement reduces external adjustment hardware and suits installations that rely on remote, menu-driven speed control.
