Product Description:

The HVE02.2-W018N/S200 is a regulated power supply unit manufactured by Bosch Rexroth Indramat within the HVE Power Supply Units series. Internally it carries the 02 series index and serves multi-axis drive systems by converting three-phase mains power into a stabilized DC bus while also providing a 300 W control-voltage output for auxiliary electronics. An internal air blower handles cooling, so the module can be installed in a sealed cabinet without extra airflow hardware.

At a rated output of 18 kW, the supply can continuously feed drives drawing up to 13 kW from the 400 V DC bus, while transient loads are accommodated by an average charging current limited to 14 A and a capacitor bank that stores 0.8 mF of internal energy. The bus capacitors reach operating voltage in 1.6 s, a short interval that reduces machine startup time yet keeps inrush below the system’s 28 A mains current ceiling at 400 V. When additional storage is required, external capacitance up to 10 mF can be connected, giving designers flexibility for large regenerative events. Design version 2 includes no extra features, so integration focuses on correct fuse sizing and thermal clearance.

For short bursts the supply releases 39 kW to the DC bus and absorbs up to 70 kWs of returned energy through a bleeder circuit rated for 1 kW continuous and a peak of 100 kW. The built-in blower keeps power input to 500 VA under full auxiliary load, and a 35 A fuse protects the mains connection. Peak demand is further managed by a short-term 20 kW capability that prevents over-voltage during rapid deceleration. Physically, the housing weighs 13 kg and measures only 100 mm in width, allowing several supplies or drives to share a narrow enclosure bay. These attributes make the unit suitable for compact, high-power drive cabinets that must control regenerated energy without external dissipators.
