Product Description:

The DKC10.3-012-3-MGP-01VRS is an EcoDrive controller manufactured by Bosch Rexroth Indramat for the DKC Drive Controllers series. With internal series code 10 and design version 3, this unit supplies regulated AC power to servo axes in automated plant equipment, managing speed and torque while protecting the connected motor and supply network. It operates from a separate 24 V AC control supply that keeps logic circuits active during power-stage shutdowns, allowing parameter retention and safe restart procedures in industrial automation lines.

The drive’s power section ties into a DC-bus that is held at 300 V, and it can continuously dissipate 400 W of heat through its heatsink and cabinet airflow. Maximum output values reach 106 V line-to-line, 2.5 A phase current, and up to 300 Hz fundamental frequency, so the controller can run high-speed servomotors without saturation. Input demand is limited to 2.2 A, matching the same figure for continuous consumption. The rated power channel delivers 12 A peak, referenced in the part code “012.” System wiring uses AWG 14 conductors, and the short DC link keeps voltage drop low over this wire size. Firmware labeled “multi interface, general purpose” at version 01 combines with interface option 10 to present standardized encoder, analog, and fieldbus ports for machine builders who need flexible integration.

Environmental and mechanical limits complete the performance envelope. Nominal operation is permitted up to 40 °C, with derated current allowed until 55 °C when ventilation is restricted. The controller’s rated phase capability of 12 A aligns with this thermal profile, ensuring overload clearing within design margins. Housing dimensions—device height 182 mm and a depth of 170 mm—let it fit shallow enclosures while keeping clearances for forced air paths. For fault containment, the power stage withstands network faults up to 5000 A RMS without case rupture, safeguarding adjacent equipment in group-mounted drive cabinets.
