Product Description:

The HCS03.1E-W0070-A-15-PSPV is a power stage manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. It functions as a drive controller that converts supply power into controlled voltage and current for servo or induction motors used in industrial automation. By handling the high-energy portion of a drive system, it supplies regulated torque and speed commands to actuators found in material-handling, packaging, process equipment, and conveyor systems where coordinated motion is required.

The controller tolerates a peak output of 70 A, enabling short acceleration or braking bursts without overcurrent trips. An enclosure rating of IP20 means it must be mounted inside a closed cabinet because the housing protects against accidental finger contact but not against liquids. Thermal management relies on internal air cooling, provided by an integrated blower, so no external ducting is required. The unit is built as design version 1. A continuous operating range of 15 to 75 kW suits medium-power axes such as pumps, extruders, and gantry drives. Its DC link uses an infeed/feedback topology, allowing recovered energy from braking axes to be shared with other axes or returned to the mains.

As part of the HCS03 line, the device mates with standardized IndraDrive control sections, encoder interfaces, and safety modules. It is categorized as an HCS Drive Controller, so it integrates gate drivers, power semiconductors, and diagnostic LEDs while leaving motion logic to pluggable control sections. This separation lets the power stage handle energy conversion while the selected control section manages axis communication and feedback processing. The arrangement supports organized multi-axis cabinet layouts where several drives share a common platform and consistent connection format.
