HVE03.2-W030N

The unit has a 100 kW regenerated (bleeder) peak power capability so it can absorb large energy influxes during braking, but since it's an unregulated DC bus (HVE type), all regenerated energy is dissipated via its bleeder resistor rather than fed back to the mains. This means for systems with very frequent or very large regen events, you’ll need good cabinet cooling and possibly external bleeder devices or design adjustments to avoid overheating.

The unit is rated for 5 °C to 45 °C ambient and up to 1000 meters elevation without derating; outside those ranges, the manufacturer advises applying “load factors”—i.e. reducing its output capability to maintain safety and reliability.

Forced‐air cooling helps keep the heatsinks and internal components within spec under load, but requires sufficient airflow inlet/outlet in the cabinet; the blower itself must be accessible or replaceable and may require periodic cleaning. Also, since regenerated heat is dumped internally (especially via the bleeder), ensure thermal management so cabinet ambient temperature doesn't exceed limits.

Yes; Bosch Indramat HVE PSUs are designed to power multiple HDD/HDS drive controllers off a common unregulated DC bus and share the control voltage via dedicated bus terminals (X1 etc.). Wiring must ensure low voltage drop, proper grounding, and that the control voltage bus is kept intact; distances and layout affect voltage drop and response

These units include an internal mains contactor that isolates the drive controllers from the AC supply once control voltage conditions or safety interlocks require shutdown, offering a safety separation; but for full safety compliance, external safety circuits, emergency stops, and proper protective devices must supplement this. Also because unit surfaces and heatsinks can become hot under load/regeneration, adequate guarding is needed
