Product Description:
The HDS03.1-W075N is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. The unit belongs to line 03 of the platform and serves as the central power stage in modular industrial automation racks, where it supports coordinated servo motion across connected axes. By converting incoming power into controlled DC and three-phase outputs, it regulates the power supplied to Indramat digital servo modules, maintains commanded motion profiles during acceleration and speed changes, and exchanges status information with higher-level PLCs through the standardized series backplane. It also links the power supply section with the downstream motor axis modules used in the rack.
Thermal management is handled by a built-in internal air blower, so the unit does not require external ducting and can move cooling air across internal heat-producing components. Under nominal conditions, the power section can continuously deliver 75 A of output current, allowing it to drive medium-sized servo motors in sustained operation. The housing has an IP10 rating under DIN 40 050, so it should be installed behind a closed panel because protection against solids is limited. Windings, busbars, and insulation materials meet Class C under DIN VDE 0110, which supports elevated internal thermal loading. Reliable operation is permitted at ambient temperatures from +5 to +45 °C without derating.
At installation heights up to 1000 m above sea level, the stated performance remains valid because cooling conditions remain within the intended operating range. Higher elevations reduce air density, which lowers cooling efficiency in the power section. When intake air rises above +55 °C, output must be derated or ventilation must be improved to protect internal components from excessive heat buildup. The electronics can withstand storage or transport temperatures from -30 to +85 °C, which supports shipment and warehousing in a wide range of climates when the unit is not operating. The unit is Version 1.
