DKR03.1-W100B-B

DKR03.1-W100B-B is manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It is a digital intelligent AC drive controller from line series 03, with design version 1 and a current rating of 100. The rated power input is three-phase AC 400–480 V with a tolerance of ±10%, supplying the main drive circuitry. Its control voltage is AC 230 V with a tolerance of ±10%, powering the control functions.

At a 4 kHz switching frequency, the controller provides approximately 26 kW of continuous drive power and supports 71 A of continuous current. Its peak drive current is also 71 A. Digital servo and resolver feedback support motor position and speed monitoring for closed-loop control.

A built-in air blower cools the unit, which has a total heat dissipation of 900 W. The internal bleeder dissipates regenerated electrical energy through the brake resistor. This resistor has 1 kW of continuous power capacity and can absorb a maximum braking energy of 150 kWs. The controller weighs approximately 49 kg.
