Product Description:

The VAU01.1Z-Z24-024-060-NN is a control component in the VAU Uninterruptible Power Supplies series manufactured by Bosch Rexroth Indramat. The module functions as the central UPS controller and maintains a regulated DC rail for automation equipment when primary energy is interrupted. During short power disturbances, it keeps control electronics active long enough for buffered operation or a controlled stop sequence instead of an abrupt dropout. This role is especially useful where PLC memory retention and communication stability must be maintained until supply conditions return or the machine reaches a safe state. By bridging power failures, it protects PLCs, drives, and sensors from data loss and uncontrolled shutdowns in production lines.

The UPS accepts two input sources, which gives machine builders flexibility when integrating it into existing control cabinets. It can be fed from a battery-backed DC source and from an alternating-current range of 100-240 V AC, allowing installation in machines that share standard single-phase feeds. Internally, it converts these inputs to a steady output of DC 24 V for logic loads, and input frequency tolerance covers 50/60 Hz so the device operates on global utility grids. The power path is intended for control-level loads rather than high-demand motion power stages. Distribution capacity is rated at 60 W, and all electronics are housed in an enclosure rated IP20 for cabinet mounting with forced or natural convection.

Hardware revision 1 uses matching terminal layouts for the IndraControl V family, allowing the UPS to fit existing DIN rail arrangements without rewiring. At 1.0 kg, the assembly adds little load to a control panel and suits compact cabinet installations where available space is limited. The unit serves as the control for a central UPS and does not include auxiliary design features, which keeps the layout focused on backup power management and system continuity. As an industrial Uninterruptible Power Supply, it stabilizes low-voltage electronics, prevents brownout-induced resets, and supports orderly shutdown procedures that help preserve process data.
