Product Description:

Bosch Rexroth Indramat builds the HVR02.1-W010N as a component of the HVR Power Supply Units series. The device is a dedicated power supply unit that converts plant-level three-phase AC into a regulated DC bus for Indramat drive systems. In a multi-axis automation cell, it functions as the central energy source, enabling synchronous operation of servo drives and reducing wiring when several inverters share the same power rail. This arrangement supports compact drive assemblies where several compatible controllers operate from one shared supply.

Its mains section accepts 3 × AC 380 V to 480 V (±10 %), so the unit tolerates typical low- and high-side fluctuations on industrial distribution networks without loss of regulation. After rectification and filtering, it provides a regulated DC bus voltage that maintains constant intermediate-circuit potential for precise torque control on connected drives. The continuous power rating is 10 kW, which is the maximum combined load the connected axes can draw while the supply remains within thermal limits. Heat generated by switching devices is removed through internal air cooling with a built-in blower, eliminating the need for separate cabinet fans. The unit is Design Version 1, which marks the first mechanical and electrical revision of the 02 platform.

Because it belongs to Series 02, the module mates electrically and mechanically with second-generation HDS and HMS drive controllers through a common backplane. The product classification is HVR Power Supply Unit, so protection, signaling, and start-up sequences follow Indramat supply conventions rather than drive-specific rules. Built-in regenerative circuitry returns excess kinetic energy from decelerating axes to the DC link instead of dissipating it as heat during rapid indexing and synchronized braking.
