Product Description:

The HVE02.2-W018N/S202 power supply unit is built by Bosch Rexroth Indramat for the HVE Power Supply Units series. As a regulated DC source, it feeds the intermediate circuit of drive controllers and provides the energy buffer required for rapid acceleration and controlled braking in industrial automation lines. The module belongs to design version 2 and series 02 within the product family. It converts three-phase mains power into a stabilized DC bus to support coordinated multi-axis motion in packaging, machining, and assembly equipment. In multi-axis systems, this allows connected drives to share a common energy source during changing load conditions.

The unit delivers a rated power of 18 kW, yet it draws only 500 VA of input power at maximum load because the DC link is replenished by regenerated energy from connected drives. Under full utilization, dissipation remains limited to 250 W of power loss, aided by an internal air path and a built-in blower that forces heat across the heat sink. The built-in bleeder resistor can absorb 1 kW of continuous bleeder power, while momentary surges are handled with a 100 kW peak capacity, converting returned kinetic energy into heat rather than sending it back to the supply network. Basic losses stay at 125 W during standby, and the control electronics draw 300 W for logic and diagnostics. With a 35 A maximum fuse, installation wiring follows standard machine-tool conventions. The module can accept 70 kWs of regenerated energy before the bleeder circuit reaches saturation.

Operation is rated up to 55 °C ambient temperature with linear derating above 45 °C, and performance is maintained to 1000 m installation altitude without additional cooling. The supply tolerates 95% relative humidity at 25 g/m³ absolute moisture, provided condensation is avoided. The unit has a mass of 13 kg and a housing width of 100 mm, which helps when planning cabinet layouts. An IP10 protection category indicates open vent slots that rely on clean control-room air, consistent with the internal blower design. Because the enclosure is open, the unit is intended for installation inside a protected cabinet rather than for exposed mounting. Power dissipation averages 7 W per delivered kilowatt.
