R911190005 (HVR03.2-W045N)

What is the significance of the peak output (135 kW for 0.3 seconds) for the Bosch Rexroth Indramat HVR03.2-W045N?

It allows the power supply to handle short bursts of high power demand—such as rapid accelerations in robotics—without overloading. Continuous use at peak can overheat the internal components unless properly managed with cooling and duty cycle constraints.

How does the regeneration (regen) energy rating affect system design?

Regen capability (≈ 80 kWs in many listings) means the unit can absorb energy fed back from motors (e.g. during deceleration) and buffer or return it, reducing external braking resistor needs. System designers must ensure proper wiring, bus capacity, and safety protection to handle the energy flow.

How does the 750 V DC bus voltage impact compatibility with servo drives/inverters?

Devices connected must be rated for that bus voltage to avoid insulation breakdown or overvoltage damage; it allows for high-power drives to be run with lower bus currents, which reduces cabling & losses. Designers should ensure drive modules (HDS/HDD etc.) and protection circuits are specified for 750 VDC.

What control or auxiliary power is needed for this power supply?

It needs ~500 VA of control / auxiliary input power to run its internal systems, blower, control electronics, etc. Failure to provide adequate control power can lead to under‐performance or inability to properly regulate voltages.

How should the HVR03.2-W045N be integrated for safe handling of regenerated energy?

Ensure the DC bus and associated capacitors/chokes can handle the peak regen current, and include overvoltage protection or braking resistors if regen exceeds buffer capacity. Also, ground and safety interlocks must comply with standards to avoid dangerous voltage buildup.
