DKR02.1-W200B

DKR02.1-W200B is a Bosch Rexroth Indramat unit in the DKR Drive Controllers series. It belongs to line series 02, uses design version 1, and has a current rating code of 200. The controller operates from a rated three-phase AC power voltage of 400 to 480 V with a tolerance of ±10%. Its control circuits require 230 V AC with a tolerance of ±10%.

At a 4 kHz switching frequency, the drive supplies approximately 47 kW of continuous power and supports 120 A of continuous current. Its peak drive current is 141 A, providing short-duration current capacity during high-load operation. Cooling is provided by air from a built-in blower, which removes the heat generated during operation. The unit has a total heat dissipation of 1,600 W and weighs approximately 104 kg.

An internal bleeder dissipates regenerated electrical energy through the integrated brake resistor. The brake resistor provides 1.5 kW of continuous braking power and can absorb up to 240 kWs of braking energy.
