HVR02.2-W010N/S203

The Bosch Rexroth Indramat HVR02.2-W010N/S203 is a robust unit in the HVR Power Supply Units series designed to supply consistent energy to DIAX 04 control systems. As a HVR Power Supply Unit, it delivers a continuous DC bus power of 10 kW and supports a peak DC bus power of 30 kW, ensuring rapid response to transient load demands. The unit accepts a mains input voltage of 3 x AC 380 V to 480 V (±10%), eliminating the need for external transformers and simplifying installation. Its primary function is to regulate and maintain the DC bus voltage for one or multiple drive controllers, ensuring stable operation and high performance in automated systems.

This second-generation design (Design Version 2) incorporates an internal air cooling system with a built-in blower, providing efficient thermal management under continuous load. The regulated DC bus voltage output ensures drive dynamics remain consistent even under undervoltage conditions, while the ability to return up to 80 kWs of regenerated energy to the mains reduces wasted power and improves overall system efficiency. The unit’s Series 02 architecture and standardized footprint facilitate seamless integration into existing racks, and its compact form factor maximizes performance density. With a highly reliable cooling method and robust power handling, this supply unit sets itself apart as a top choice for demanding industrial environments.

Designed for operational flexibility, the HVR02.2-W010N/S203 is compatible with 3-phase AC networks worldwide and can accommodate dynamic braking by leveraging its DC bus as a brake resistor. Internal electrolytic capacitors ensure smooth voltage delivery, though periodic operation is recommended during extended storage to maintain capacitor health. While no external certification details are provided, the product’s adherence to Bosch Rexroth Indramat’s rigorous manufacturing standards implies high reliability and longevity. In industrial applications, this power supply unit enhances system uptime, reduces energy costs through regeneration, and delivers precise voltage regulation, making it an essential component for high-performance drive systems.
