Product Description:

The EFC3610-18K5-3P4-MDA-NN-NNNNN-NNNN is a three-phase frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. As part of the EFC 3610 model series and product line 02, it operates between a fixed 400 V AC supply and an induction motor to provide variable voltage and frequency. This allows connected equipment to match speed and torque demand without mechanical gear changes, and it makes the unit suitable for general-purpose automation that requires compact drive control and standard interfaces.

The converter accepts a 380 to 480 V line supply and draws 45.8 A at 380 V while delivering 39.2 A to the motor. Its apparent power limit of 25.8 kVA corresponds to a continuous motor rating of 18.5 kW, and the same power rating applies in heavy-duty operation. A short-term overload capacity of 150% (60 s) allows the drive to support acceleration peaks without immediate tripping. Speed regulation is handled by Enhanced V/Hz control, and the default carrier frequency is 6 kHz. The Flex-Control section uses Standard I/O with five digital inputs, one relay output, and an RS485 communication link that supports Modbus protocol. The control configuration is standard, and the unit does not include an integrated safety function.

Cooling is provided by forced air, with a heat sink blower moving 1.13 m³/min across the power stage and an internal fan circulating 0.99 m³/min inside the housing. Under nominal load, the converter dissipates 530 W of heat, so the enclosure must allow adequate ventilation for heat removal. The housing has an IP20 rating, and a factory-fitted EMC filter meets industrial-area class C3. The unit measures 315 mm in height, 165 mm in width, and 241 mm in depth, which places it in frame size G. A dust-covered front panel means the drive does not include a local display.
