We offer Power Pack with Battery Backup designed to provide reliable and uninterrupted DC power for industrial control and protection systems. This unit converts AC mains supply into regulated DC output while simultaneously charging the connected battery. In case of mains failure, the battery automatically supplies power without any interruption, ensuring continuous operation of critical equipment.

The power pack is manufactured using high-quality components and is suitable for substation panels, relay & control panels, annunciators, and industrial automation systems. It is built for long-term reliability, stable performance, and low maintenance.
