R911190001
The R911190001 (HVE03.2-W030N), a second-generation power supply unit, is made by Bosch Rexroth Indramat for connecting to HDD and HDS drive controllers. Integrated into the module is a power rectifier, which serves the purpose of rectifying three-phase AC voltage, making it an essential member of the DIAX04 family group. A key feature includes the ability to be disconnected from the mains by an internal power contactor while communicating with the drive controller via the control bus voltage. Uniquely, the unit supports multiple connections to different drive controllers and can be combined with a GLD DC bus choke to enhance the usable DC bus continuous power. However, overloading may lead to damage. The device operates optimally at a frequency range of 50Hz to 60Hz +/-2Hz and at a temperature between 5°C and 45°C (rated).
Additional features of the R911190001 (HVE03.2-W030N) include its ability to handle the application of short-term loads required for accelerating spindle and feed drives, a feature guided by the connected load of the module. The DC bus can be connected with 10mF additional capacitance, although load factors must be considered when the unit is operated under unspecified conditions. Other operational considerations include heat loss in the control cabinet and surface heating during operation, whilst condensation may occur due to the use of a cooling unit. Despite its versatility, users should note that the unit lacks protection against intentional access. Importantly, the R911190001 (HVE03.2-W030N) can be shipped to any global location.
