Product Description:
The HVE02.1-W018N is a power supply unit manufactured by Bosch Rexroth Indramat for the HVE Power Supply Units series. It converts three-phase mains power into a regulated DC bus that feeds connected drive controllers in industrial automation cabinets. This allows multiple linked axes to share a common supply during operation. By integrating an internal bleeder stage, the module absorbs regenerative energy from servo axes, and its built-in air blower removes the resulting heat without requiring external braking hardware.
The supply accepts a three-phase input of 3 x 380–480 V (±10%) at 50–60 Hz and delivers a DC bus between 530–670 V for linked inverters. It is rated for 18 kW, and when fed from 400 V lines it can furnish 13 kW of continuous DC output. Under nominal conditions the mains draw reaches 28 A, so a 35 A semiconductor fuse is required for protection. Control electronics consume 500 VA and are supplied by an internal 300 W source, which keeps the control section powered inside the same unit. Heat is dissipated by internal air circulation, which limits power loss to 250 W at full output and keeps idle losses to 125 W. Rated service is maintained from +5 °C to +45 °C, at elevations up to 1000 m above sea level, and at relative humidity up to 95% without condensation.
The bleeder resistor can dissipate 1 kW continuously and can tolerate peaks of 100 kW during rapid deceleration. The capacitor bank absorbs up to 70 kWs of regenerated energy before the DC voltage reaches its threshold. When ambient temperature approaches the derated ceiling of +55 °C, the output must be reduced to stay within thermal limits. The assembly weighs 13 kg, carries series designation 02, and may be stored or transported safely between –30 °C to +85 °C.
