HVR03.2-W045N/S202

The Bosch Rexroth Indramat HVR03.2-W045N/S202 from the HVR Power Supply Units series is a high-performance HVR Power Supply Unit engineered for demanding servo-drive and CNC systems. It delivers a Power Output of 45 kW from a three-phase Mains Input Voltage of 3 x AC 380 V to 480 V (±10%), converting incoming power into a regulated DC bus voltage that ensures consistent drive performance. Built on a Design Version 2 platform with rugged electronics and a series “03” control topology, this unit maximizes compatibility with existing Rexroth modules. Thanks to a Peak Power rating of 135 kW, the HVR03.2-W045N/S202 can meet transient load peaks without derating.

Thermal management relies on Internal Air with built-in blower cooling, which maintains internal components within safe operating temperatures even under extended duty. Capable of absorbing a Maximum Regenerated Energy of 80 kWs, the unit recovers kinetic energy during rapid deceleration, reducing external resistor bank requirements and lowering system energy costs. In line with its Series 03 architecture, there are Other Design Details: None, simplifying the product configuration and minimizing engineering overhead. Enhanced surge tolerance and overload protection are engineered into the power stage to protect against grid disturbances and transient spikes.

Installation and commissioning are streamlined through standardized form factors, consistent connection layouts, and clear instrumentation for voltage, current, and fault diagnostics. Rigorous validation under fluctuating line conditions and extensive thermal cycling guarantees long-term reliability in industrial environments. The HVR03.2-W045N/S202 stands as a robust solution for motion control applications that demand high power density, efficient energy recycling, and uninterrupted performance.
