Aside this Servo-AVR, Vetronic D-G UPS is a special Line-interactive UPS Topology that constantly monitors the input line for voltage fluctuation and auto-corrects main output to connected load with a very wide input-window in-built AVR. The inversion system takes over when input mains fails or exceeds the very wide UPS input thresholds. The Vetronic D-G UPS is built on well-tested and reliable technology that offer high value to diverse customers in different applications. This is achieved through provision of connected loads with regulated supply, protecting against input voltage anomalies and ensuring that battery power is reserved as much as practicable, for most critical use during moments of outage. The line-interactive topology ( D-G Series UPS) assures seamless transition time between input source and battery during outages. This is ideally suited for modern sensitive applications that cannot afford the fastest manual power source transfer.

Key Features of Vetronic D-G UPS

Line- Interactive Topology: It constantly monitors the input line for voltage fluctuation and auto-corrects mains output to connected load with a very wide input-window in-built AVR.

High power density: Small footprint for space -efficient applications

Friendly Status Interface: Attractive status interface: normal mode, battery mode/ main fails, low battery and UPS fault.

Cold Start Function: Starts on battery without input mains

Sleek and Rugged Physical Profile: Durability inside-out with sleek, rugged enclosure.


The Vetronic FS Online is a Mid-Range Model UPS that offers a range of capabilities of 1kva to 20kva for flexibility of choice as desired by the Customer. This conversion topology offers highest quality of power to connected loads as the AC output is always freshly synthesized by the inversion system within the UPS, from the DC pool of the rectifier, with 0ms transfer time. The double-conversion online topology provides connected loads with a very clean, freshly-synthesized supply, protecting against inputs mains anomalies. Additionally, they are double conversion online systems carefully engineered to offer discerning customers enhanced power availability.
