Bosch Rexroth HVR02.2-W025N – Regenerative Power Supply Unit | IndraDrive HVR Series
Engineering Background
The HVR02.2-W025N is a regenerative mains supply unit from Bosch Rexroth’s IndraDrive platform — one of the most widely deployed servo drive architectures in precision manufacturing, packaging, and process automation. Designed to feed DC bus power to multiple IndraDrive axis modules simultaneously, this unit eliminates the need for individual power supplies per axis, dramatically reducing panel footprint and wiring complexity.
Product Positioning
Targeted at OEM machine builders and system integrators operating multi-axis servo systems, the HVR02.2-W025N delivers 25 kW of continuous DC bus power with active regeneration — returning braking energy to the mains rather than dissipating it as heat. This makes it the preferred choice for high-cycle applications where energy efficiency and thermal management are critical design constraints.

- Semiconductor & Electronics Assembly – Cleanroom-compatible servo systems with strict thermal budgets
- Robotics & Gantry Systems – Coordinated multi-axis motion with shared DC bus architecture
Engineering Advantages
- Active Regeneration: Returns up to 100% of braking energy to the mains grid — reduces energy consumption by 20–40% vs. resistive braking in high-cycle applications
- Shared DC Bus: One HVR02.2-W025N can power multiple IndraDrive axis modules simultaneously, minimizing cabinet space and BOM cost
- Low Harmonic Distortion: Active front-end topology reduces mains THD, protecting sensitive plant equipment and meeting IEEE 519 requirements
- Integrated Diagnostics: On-board status LEDs and error code output compatible with Rexroth IndraWorks engineering software
- Hot-swap Ready: Designed for rapid field replacement without full system shutdown in supported configurations
- Wide Input Voltage Range: 380–480 V AC ±10% accommodates global mains variations without external transformers
System Architecture & Signal Flow
The HVR02.2-W025N operates as the mains interface node in an IndraDrive multi-axis topology:
- Mains Input (L1/L2/L3): 3-phase AC power enters through the line filter and EMC choke
- Active Rectifier & PWM Front-End: IGBT-based active rectifier converts AC to regulated 750 V DC bus with sinusoidal current draw
- DC Bus Distribution: Internal bus bars distribute DC power to all connected HCS/HMD/HMS axis modules via the IndraDrive power bus connector
- Regeneration Path: During motor braking, axis modules feed energy back to the DC bus; the HVR front-end inverts excess energy back to the mains
- Control Interface: The unit communicates drive status and fault conditions to the master controller via the IndraDrive system bus

Technical FAQ
Q: Can the HVR02.2-W025N replace an HVR02.2-W018N in an existing system?
A: Yes, provided the cabinet has adequate space and the mains supply can support the higher rated current. The DC bus interface is identical across the HVR02.2 family.
Q: Is a line reactor or EMC filter required?
A: Bosch Rexroth recommends a matched HNL line choke and HNF mains filter for full CE compliance and optimal harmonic performance. Contact us to source the matching filter set.
Q: What IndraWorks version is required for commissioning?
A: IndraWorks DS 14V08 or later is recommended. Firmware updates can be applied via the SERCOS interface during commissioning.
Q: Can this unit operate in a 60 Hz / 480 V North American installation?
A: Yes. The HVR02.2-W025N is rated for 380–480 V AC at 50/60 Hz and carries UL/cUL certification for North American markets.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time depending on sourcing channel. Contact us for real-time availability.
