Working as a redundant power backup

This system is designed for 1+1 redundancy projects, offering cost-efficient and reliable power protection. By integrating two UPS units, it ensures higher availability compared to a single UPS setup.

Under normal conditions, the master UPS supplies power to the connected load, while the slave UPS remains in standby mode. If the AC mains fail but the master UPS continues to operate, it will keep powering the load without interruption.

In the event of a master UPS fault, the system automatically switches to the slave UPS, ensuring continuous backup power. Once the master UPS is repaired or replaced, it can be seamlessly re-integrated into the system, automatically resuming its role as the primary power source.

This provides a simple, reliable, and cost-effective redundancy power backup solution.

Automatic Maintenance Bypass Switch (ABMS) Operation

When a fault occurs in the master UPS, the ABMS automatically transfers the load to bypass mode, allowing the AC mains to directly supply power to the connected equipment. Once the master UPS has been repaired or replaced, the system seamlessly switches back to the UPS to resume uninterrupted backup power.

Working as an Automatic Transfer Switch (ATS)

When both the AC mains and the master UPS are operating normally, the master UPS supplies power to the connected loads. If the AC mains fails, the master UPS continues to provide uninterrupted power to the loads. Once the master UPS battery is depleted, the backup system will automatically switch to the generator to ensure continuous power. After the master UPS is repaired or replaced, the system will automatically transfer back to the master UPS for ongoing backup power.
