Product description

What to know about HVR03.2-W045N

The HVR03.2-W045N is a Bosch Rexroth Indramat HVR power supply for DIAX 04 drive systems. Unlike an HVE unit, the HVR family uses a regulated DC bus and can return regenerative energy to the mains when the machine decelerates.

Published project-planning data identifies the HVR03.2-W045N with a 3 × AC 380–480 V mains range, 50–60 Hz input and a regulated 750 V DC bus. The 045 type code identifies the 45 kW family configuration, and W denotes cabinet air cooling by a built-in blower.

Confirm the complete nameplate, line conditions and connected drive load before substitution. Litco can check shelf condition and supply current unit photos with a quote.
