Product Description:

The VAU01.1S-230-230-300-NN is an uninterruptible power supply produced by Bosch Rexroth Indramat within the VAU Uninterruptible Power Supplies series. The unit is designed to maintain a stable AC bus for drive controllers and PLC hardware when mains power dips or fails, which helps prevent uncontrolled shutdowns in automated production cells. It uses a true offline topology, so recharge current is drawn only when incoming mains conditions are within the permitted range. Because the load normally runs directly from the mains, the stored backup energy is held in reserve for interruption events instead of continuous power conversion. This role makes the unit suitable for supporting control platforms that need ride-through power without added communication or active control functions.

Incoming power is accepted at AC 230 V and a line frequency of 50/60 Hz, and the electronics tolerate voltage variation of up to ±10% without derating. Internally, the unit supports a maximum continuous output of 300 W, which is suitable for several low-power control loads or HMI panels. That output level is intended for control electronics rather than large motor loads, so the UPS is focused on keeping essential automation hardware active during short supply interruptions. The housing has an IP20 rating, so the unit is intended for installation inside a switch cabinet. No communication interface is fitted, and the UPS is used for power backup rather than networked control tasks.

This model is part of the IndraControl V accessory family and uses the Standard mechanical layout. The unit is listed as design revision 1, so associated drawings and part references should match that revision. Its metal enclosure weighs 3.5 kg, which helps keep cabinet loading moderate while maintaining a sturdy housing. The standard layout supports installation in the intended panel position, and the metal enclosure adds rigidity for fixed mounting beside control hardware.
