The TechSay SDE 1011XR single-phase UPS uses On-Line Double Conversion technology to deliver clean, stable, and pure sine wave power at 10KVA capacity. Its rack-mount design makes it an ideal choice for data centers, server rooms, and critical network infrastructure.
With a digital signal processor (DSP) and an efficiency of over 94% at full load, the SDE 1011XR precisely regulates voltage, frequency, and battery charging while minimizing energy waste.
Zero transfer time ensures that connected equipment experiences no interruption during power failures or fluctuations, protecting servers and sensitive electronics from data loss and hardware damage.
The intelligent battery management system extends battery service life by adjusting charge current and discharge voltage, preventing premature wear and overheating.

Frequently Asked Questions
Is the SDE 1011XR suitable for rack server environments?
Yes, its rack-mount form factor, 10KVA capacity, and pure sine wave output make it perfectly suited for standard 19-inch racks, protecting servers, switches, and storage systems in data centers.
Does this UPS include internal batteries?
No, the SDE 1011XR requires an external battery pack. It is equipped with a ceramic terminal to connect a 192 Vdc battery bank consisting of 16 12V batteries.
Can the UPS operate in ECO mode to save energy?
Yes, ECO mode boosts efficiency above 98% by routing filtered mains power directly to the load. While energy savings are substantial, full online mode is recommended for maximum protection of sensitive equipment.
