The UPS system includes multiple protection features such as overload protection, short-circuit protection, and battery management systems. These features work together to safeguard both the UPS and connected equipment, providing peace of mind in critical operations.
User-Friendly Interface
The intuitive LCD display offers real-time monitoring of UPS status, battery health, and operational parameters. Users can easily access vital information and manage settings for optimal performance.
Durable Construction
Built with industrial-grade components and robust chassis to withstand harsh operating environments.

The GLT33120 Online UPS is ideal for various applications, particularly in industries where CNC machines play a vital role, including:
Uninterruptible Power Supplies (UPS) are critical components for CNC machines and other sensitive equipment in manufacturing environments.
CNC machines are often sensitive to power fluctuations and interruptions. A UPS provides immediate backup power during outages, ensuring that machining operations can continue without interruption, thus preventing costly downtime.
The CNC machines rely on complex software and control systems. Sudden power loss can lead to data corruption, loss of programming, or incomplete machining processes. A UPS safeguards against these risks by providing a temporary power source, allowing for safe shutdown procedures.
By minimizing downtime caused by power interruptions, a UPS helps maintain continuous production flow. This translates to higher productivity levels and improved efficiency, as operators can rely on their machines to perform consistently.
The sudden loss of power can lead to safety hazards, as CNC machines stop abruptly. UPS systems allow for controlled shutdowns, reducing the risk of accidents and injuries associated with unexpected machine stops.
CNC machines often operate alongside other electronics and devices. A UPS provides cleaner power, reducing interference and ensuring reliable operation of all connected equipment.
