Power and Electrical Performance of the Bosch Rexroth DKC10.3-012-3-MGP-01VRS
One of the first questions any designer asks is whether a servo drive can deliver the power and current their application requires. The Bosch Rexroth DKC10.3-012-3-MGP-01VRS runs on a 200…240 V AC mains supply (with a typical usable range from around 170 to 265 V AC), which makes it a natural fit for many small machines fed from single‑phase or three‑phase low‑voltage networks.
The DC‑bus inside the Bosch Rexroth DKC10.3-012-3-MGP-01VRS operates at a nominal 300 V DC, with a rated bus current of 12 A. This 12 A rating does not mean the connected motor draws 12 A directly; it refers to the DC‑bus current that supports the 3‑phase AC supplied to the motor. Due to conversion efficiency and power factor relationships, the actual phase current to a 400 W servo motor is usually several amps—enough to deliver high acceleration and short positioning times when driven by the Bosch Rexroth DKC10.3-012-3-MGP-01VRS.
To protect the internal components during power‑up, the Bosch Rexroth DKC10.3-012-3-MGP-01VRS includes a soft‑start resistor (around 4.7 Ω, rated at approximately 17 W). This soft‑start circuit limits inrush current when the DC bus charges, which helps extend the life of the drive and upstream components. In everyday operation, this is invisible to the user, but it highlights the robust design of the Bosch Rexroth DKC10.3-012-3-MGP-01VRS.
The control electronics of the Bosch Rexroth DKC10.3-012-3-MGP-01VRS are powered by an internal 24 V supply derived from the main 230 V input, so you do not usually need a separate external 24 V power unit. This simplifies wiring and reduces panel component count, while still allowing the Bosch Rexroth DKC10.3-012-3-MGP-01VRS to maintain clear separation between power and control sections.
Environmental Limits and Cabinet Design with the Bosch Rexroth DKC10.3-012-3-MGP-01VRS
Even the best servo drive fails early if it is installed in the wrong environment. The Bosch Rexroth DKC10.3-012-3-MGP-01VRS is designed exclusively for mounting in a control cabinet, with a protection class of IP20. This means the Bosch Rexroth DKC10.3-012-3-MGP-01VRS relies on the cabinet to provide the extra shielding against dust, moisture, and accidental contact.
For rated performance, the Bosch Rexroth DKC10.3-012-3-MGP-01VVRS needs an inlet air temperature in the range of 0…+40 °C.
