Product Description:

The EFC5610-2K20-1P2-MDA-7P-NNNNN-L1NN is a frequency converter manufactured by Bosch Rexroth Indramat for the EFC Frequency Converters series. Mounted inside a control cabinet, the unit changes fixed utility power into a variable voltage and frequency output. This modulation lets the drive regulate asynchronous motor speed on conveyors, pumps, or light process equipment without mechanical gearboxes or flow restrictors, improving energy use and startup smoothness. The adjustable output also helps reduce mechanical shock during motor starts and supports steadier process control when load demand changes.

Electrically, the converter accepts a supply of 1-phase 200 VAC and synthesizes a variable 3-phase AC waveform through its internal IGBT bridge. The power section is rated for a continuous motor load of 2.2 kW, matching small and medium induction motors. Under nominal conditions, the drive draws 22.3 A at 200 V and can provide the motor with up to 10.1 A at 200 V. These values guide the sizing of upstream breakers, contactors, and cables, while also setting the available current margin during acceleration. Pulse-width modulation adjusts both frequency and voltage so the connected motor can maintain stable torque across the requested speed range during changing operating conditions.

A fan provides forced-air cooling, allowing apparent power delivery of 3.5 kVA without temperature derating. Input short-circuit protection is coordinated for a 32 A fuse, helping limit excessive fault energy at the supply side. Motor conductors terminate on screw clamps rated for 6.0 mm² copper, while the protective-earth conductor is limited to 4.0 mm² to match the terminal arrangement. Installation uses M3 terminal screws tightened to 1.00 N·m, which helps keep contact pressure stable under vibration. Clear terminal sizing and active cooling make the unit easier to integrate into compact control panels with limited wiring space.
