HVR03.2-W045N

The Bosch Rexroth Indramat HVR03.2-W045N is a high-performance power stage in the HVR Power Supply Units series designed for industrial drive applications. Featuring a Mains Input Voltage range of 3 x AC 380 V to 480 V (±10%) and a regulated DC bus voltage of 750 Volts DC, this module efficiently converts three-phase AC input into a stable DC output. With a nominal Power Output of 45 kW and three-phase AC input at 50 to 60 Hertz, its primary function is to supply constant DC bus power to servo drives and inverters for precise motion control.

Incorporating an internal air cooling scheme with built-in blower, the HVR03.2-W045N maintains optimal thermal performance even under sustained load conditions. The unit delivers a continuous DC bus power output of 30 kW and a peak output of 135 kW for up to 0.3 seconds, enabling rapid acceleration and high-torque bursts. The peak bleeder power is 80 kW, and it can handle a maximum regenerated energy of 100 kWs. Power losses at maximum continuous output are limited to 626 Watts, with basic losses of 175 Watts and specific losses of 24 W/kW, underscoring its efficiency in power conversion. Unique design version 2 enhances reliability, while a vertical mounting orientation simplifies cabinet integration.

Designed for rugged industrial environments, this power stage carries a protection rating of IP10 per DIN 40 050 and requires an installation clearance of 300 millimeters to ensure adequate airflow. The permissible ambient temperature for optimal performance ranges from 5 to 45 degrees Celsius, with derated operation up to 55 degrees Celsius and storage conditions from -30 to 85 degrees Celsius. Maximum operating elevation is 1000 meters above sea level, and relative humidity can reach 95% (absolute humidity up to 25 g/m³). Weighing 24 kilograms, the unit draws a maximum control power of 850 VA and supplies 500 Watts of control voltage output. Its robust construction and precise regulation make the HVR03.2-W045N an excellent choice for enhancing reliability, efficiency, and performance in demanding industrial automation systems.
