EFC3600-0K40-3P4-PDA-7P-NNNN

The Bosch Rexroth Indramat EFC3600-0K40-3P4-PDA-7P-NNNN from the EFC Frequency Converters series integrates seamlessly into industrial automation setups with a continuous power of 0.4 kW, a connection voltage of 400 V, and a native Profibus communication module. It draws 1.3 A input current from a 3-phase AC 380–480 V, 50/60 Hz supply with a tolerance of –15%/+10%, delivering a variable output frequency ranging from 0 to 400 Hz. The converter achieves an efficiency greater than 95% while operating at a programmable switching frequency between 1 and 15 kHz, providing precise speed control and energy savings. Compact and robust, this module mounts vertically and supports dense cabinet installations without derating.

The front-mounted control panel is removable and divided into two functional areas: a 4-digit, seven-segment display for real-time status and error codes, and a tactile key array for parameter programming. An integrated LED indicator clearly signals rotational direction and operating mode, facilitating rapid diagnostics. Internally, a brake chopper regulates voltage flow to an external brake resistor, supporting dynamic braking and motor stop functions. The converter’s lack of side ventilation holes and reliance on natural convection cooling permit side-by-side installation of multiple units without forced airflow requirements.

Measuring 196 mm in height by 95 mm in depth and weighing just 1.18 kg, the EFC3600-0K40-3P4-PDA-7P-NNNN strikes an excellent balance between size and performance. Rated to protection class IP20, it operates reliably in ambient temperatures from –10 °C to +50 °C at altitudes up to 1,000 meters without additional derating. Supplied with a one-year warranty from Wake Industrial, this frequency converter delivers dependable, energy-efficient motor control for packaging lines, conveyor systems, and general machinery automation.
