R911290393
The R911290393 (HVE03.2-W030), a second-generation power supply unit from Bosch Rexroth Indramat, serves as a conduit between drive controllers, specifically HDD and HDS models. An integrated power rectifier translates three-phase AC voltage within this module from the DIAX04 family. Communication with the drive controller is facilitated through control bus voltage, allowing one power supply unit to connect with several controllers. Adding a GLD DC bus choke to the configuration enhances usable DC bus continuous power. It boasts a frequency range of 50Hz to 60Hz +/-2Hz and operates effectively between 5°C and 45°C. However, it warns against potential damage from overloads. The unit can manage short-term loads for spindle and feed drives acceleration.
The DC bus of the R911290393 (HVE03.2-W030) can accommodate up to 10mF of additional capacitance. Its operation outside of stipulated conditions ought to consider load factors. Heat loss in the control cabinet can result from bleeder, power, and intrinsic losses while condensation may result from using a cooling unit. The unit, which isn't safeguarded against intentional access, can observe a considerable temperature rise on its surface during operation. Interestingly, this power supply unit is available for international shipping.
