The EFC5610-11K0-3P4-MDA-7P-NNNNN-L1NN from Bosch Rexroth Indramat in the EFC Frequency Converters series delivers an 11.0kW continuous power rating at a 400V connection voltage with an integrated Modbus communication module. This converter features a built-in brake chopper for rapid energy dissipation and supports a 50/60Hz power supply frequency with ±5% tolerance, ensuring smooth operation under fluctuating supply conditions. It generates a 200% start-up torque at 0.5Hz, allowing motors to overcome initial inertia with ease. The unit is housed in an IP20 protection class enclosure, safeguarding internal electronics from solid particles while maintaining serviceability.
Thermal management is handled by an enforced air cooling system that maintains optimal junction temperatures across an operating range of –10°C to +45°C. Beyond 45°C, the device incurs a 1.5% derating per °C up to 55°C, ensuring reliable performance without thermal shutdown. A user-configurable DC braking time from 0 to 20s enables controlled deceleration, while digital command integration includes one open collector output and one relay output. Two flexible analog outputs provide 0–10V or 0–20mA signaling, and RS-485 communication employs shielded twisted-pair cables for noise immunity. Motor connection is simplified via U, V, and W output terminals, and when paralleling DC buses, a mains choke is required to balance current.
Additional safety and convenience features include a 50A maximum charging current specification and a relay output that remains inactive under normal operation to indicate fault states clearly. The converter is certified to meet EN 50178 degree of protection level 2, ensuring compliance with industrial safety standards. Each unit ships with a one-year warranty and is secured in custom military-grade packaging to protect against transit shock and moisture.
