DKS01.1-W050A-RA01-00

DKS01.1-W050A-RA01-00 is a Bosch Rexroth Indramat unit in the DKS Intelligent Digital Servo Drives series. It is version 1 and operates from a three-phase 230 V AC input at 50–60 Hz. The rated current is 50 A, while the maximum-load power requirement is 9.5 kVA. Its bus DC voltage and internal DC bus voltage are both 300 V, providing the DC link used by the drive’s power stage. The 4 kHz PWM frequency controls power delivery to the connected motor.

The bleeder handles 0.35 kW continuously and up to 9.4 kW at peak, allowing excess DC bus energy to be dissipated during braking. Cooling is provided through heat dissipation to remove operating heat. Power loss at maximum device load is 305 W, and the separate maximum-load power-loss rating is also 305 W. The maximum derated ambient temperature is +55ºC. Maximum elevation is 1,000 m, and operation without derating is supported up to 1,000 m.

The drive has an IP10 protection class, providing protection against access by large solid objects but no rated water protection. Noise emission is standard.
