Product Description:

The EFC3610-18K5-3P4-MDA-7P-NNNNN-NNNN is a variable-speed drive from Bosch Rexroth Indramat in the EFC Frequency Converters series. Designed for cabinet installation, the converter supplies adjustable three-phase output to asynchronous motors used in pumps, fans, and general material-handling systems. By synthesizing a controllable AC waveform, it supports energy-efficient process control across a broad speed range while occupying a moderate footprint inside plant electrical enclosures. This makes the unit suitable for applications that need stable speed control and straightforward integration with common industrial motor loads.

Electrically, the converter delivers 18.5 kW of continuous power for the connected motor and draws up to 39.2 A from the supply under rated load conditions. An external 80 A gG fuse is recommended to protect the input circuit, and the power terminals accept a tightening torque of 3.73 N·m to maintain low-resistance joints. Scalar control is implemented through the V/f algorithm, allowing straightforward tuning for standard squirrel-cage motors. Parameterization and status information are shown on a bright 7-segment LED panel, while remote commands and diagnostics travel over the RTU Modbus fieldbus for communication with PLCs and SCADA systems.

The housing measures 165 mm wide, 315 mm high, and 241 mm deep, and it weighs 8.0 kg. It offers panel mounting through four 6.5 mm holes that match standard M6 hardware, which helps keep the unit secure inside a control cabinet. The converter carries an IP20 enclosure rating, so it must be placed inside a protected cabinet while still allowing natural convection around the finned heat sink. Emitted radio-frequency noise meets Class C3 limits, permitting use in industrial areas with dedicated filtering on the mains. Continuous performance is maintained at elevations up to 1,000 m above sea level without output derating, making the unit suitable for most factory-floor locations.
