Product Description:
The VAU01.1U-24-24-240-NN is an auxiliary power module built by Bosch Rexroth Indramat and assigned to the VAU Uninterruptible Power Supplies series. In an automation cell, it operates as a buffer between the plant’s 120/240 V AC mains and the 24 V DC electronics that run controllers, safety relays, and communication gateways. By delivering stabilized backup energy during voltage dips or complete power loss, the device lets PLC programs finish their scan cycle and record diagnostic events, and it gives servo axes time to ramp down in a controlled manner, reducing the risk of mechanical damage or scrap. The buffered supply helps keep low-voltage control hardware active long enough for an orderly shutdown instead of an abrupt interruption.
The unit carries an enclosure rating of IP20, meaning its housing prevents finger contact with live conductors but must be installed inside a cabinet. With a mass of 3.5 kg, it mounts on a DIN rail or panel without extra support. Service access is through a USB port for retrieving event logs and performing battery calibration. As an Uninterruptible Power Supply (UPS), its internal cells instantly cover the 24 V load when the rectified input drops, which helps avoid brownout resets in digital I/O. Its outline and connectors match the IndraControl V family, so it can sit next to embedded PCs and motion controllers without adapters.
The hardware uses a standard construction with a USB interface, so the front-panel ports and LEDs follow a consistent layout. The power stage is built to design revision 1. Its form factor aligns with DIN rail hardware common in control cabinets, which simplifies installation beside existing feeders. This arrangement keeps status indicators and service access on the front of the unit, which is useful in narrow control cabinets. The module can be installed beside existing 24 V distribution equipment without special adapters or custom brackets.
