Product Description:

The VAU01.1S-230-230-255-NN is an uninterruptible power supply produced by Bosch Rexroth Indramat for the VAU Uninterruptable Power Supplies series. It supports IndraControl automation controllers by providing temporary line power whenever the primary source fails. By buffering the 230-volt circuit, the module prevents unexpected stop conditions and allows drives and PLCs to complete programmed shutdown routines without data loss.

This UPS is designed for universal European mains. It accepts a nominal input of AC 230 V over a frequency band of 50/60 Hz. The incoming supply may swing within ±10% of the set value, and the output remains within a non-bold ±10 % window, so downstream equipment continues to see a stable line. An enclosure rating of IP20 limits ingress to fingers or similar objects and requires installation inside a cabinet with controlled airflow. Because the interface list is None, the unit operates as a stand-alone energy buffer without communication ports, simplifying wiring and improving noise immunity. The nominal output is AC 230 V, matching the input so protective devices downstream do not need to be recalibrated.

Mechanical attributes follow the series baseline. Design revision 1 reflects the first hardware iteration and is identified as the current supported build. The construction is classified as Standard, meaning no custom cooling or mounting variants are included. With a mass of 3.5 kg, the module can be secured directly on DIN rail or panel without additional support. Compatibility with IndraControl V stations ensures the charger, battery pack, and filtering circuits meet the hold-up and ride-through requirements specified for that product family. No other design features are declared, so integrators only need to verify cabinet space and ambient temperature to bring the UPS online.
