R911272144
The R911272144 (HVR03.1-W045N) is a second-generation power supply unit crafted by Bosch Rexroth Indramat, forming part of the DIAX04 product selection. Designed for use with Bosch Rexroth’s HDS and HDD drive and control systems, this module operates on a regulated DC bus voltage. It accommodates a mains voltage of 3 x 380 to 480VAC within a +/-10% tolerance and a frequency range of 50 to 60Hz. The device includes monitoring functions and generates control voltage for the linked drive controller. Suitable for motors with an ongoing mechanical power ranking up to 36kW, it must be stationed in a closed housing or control cabinet. The R911272144 (HVR03.1-W045N) has an IP 10 protection rating as per the IEC 529 regulations and incorporates a power rectifier for three-phase AC voltage conversion. It also facilitates energy reversal into the mains when the connected motor operates in generator mode.
The power supply unit from the HVR series produces a regulated DC bus voltage for associated drive controllers and houses a bleeder module for braking control during mains failure scenarios. It is not designed for extreme temperature fluctuations or underwater use. The device operates optimally between 5°C and 45°C with rated data, offering protection from objects over 50mm in diameter penetration. The R911272144 (HVR03.1-W045N) can be sent safely to any global location.
