HVR02.2-W025N
HVR Power Supply Units
The HVR02.2-W025N from Bosch Rexroth Indramat provides 25 kW continuous power and rectifies three-phase AC. Part of the HVR Power Supply Units series, it accepts 380–480 V AC input and delivers 75 kW peak output. It delivers a regulated 750 V DC bus, uses internal air cooling, and has an IP10 protection rating.
It operates from 5–45 °C at rated load and up to 55 °C derated, weighing 21 kg. Regenerated energy in generator mode returns to the mains. It communicates with drive controllers via its DC control bus.

Frequently Asked Questions
How does the HVR02.2-W025N’s IP10 rating affect its installation environment?
IP10 only protects against solid objects bigger than ~50 mm but offers no protection against dust or water ingress. So it should be installed in clean, dry cabinets with controlled airflow and minimal exposure to contaminants.
What is the line fuse rating and conductor size required for the mains input for this unit?
For the HVR02.2-W025N, maximum mains fuse current is ≈ 50 A (per EN standards) with recommended conductor cross-section ~ 10 mm². Ensuring correct fuse and wiring prevents voltage drops and overheating under full load.
What happens to regenerated energy when the unit is in generator mode?
Excess energy from braking or deceleration is fed back into the AC mains (i.e. regenerated), rather than dissipated internally as heat. This improves energy efficiency and reduces thermal stress on components.
How much power is lost at full continuous load, and what does this imply for cooling requirements?
At full continuous output (25 kW) it has a power loss of about 750 W, which must be removed via its built-in air-blower and ventilation. This means cables, enclosure, and blower capacity must accommodate this heat load to avoid thermal derating.
What is the product code and how does Bosch Rexroth specify its regenerative capability?
The Bosch Rexroth HVR02.2-W025N is specified with a peak regeneration power of up to roughly 75 kW for short durations (~0.3 s), with a maximum regenerated energy of ~80 kWs in certain variants (e.g. S204 revision) for handling braking energy.
