TechSay SDE 1011XT Single-Phase UPS
The TechSay SDE 1011XT is a single-phase online double-conversion UPS delivering stable, pure sine wave power to the most sensitive electronic equipment. With a rated power of 10kW, it provides comprehensive protection against voltage fluctuations, power outages, and line disturbances, safeguarding your critical data and hardware.
Key Features & Technology
The SDE 1011XT employs a dedicated digital signal processor (DSP) to precisely regulate voltage, current, and frequency, ensuring maximum output stability under all load conditions.
Its pure sine wave output with less than 1% total harmonic distortion in voltage (linear load) delivers the cleanest power possible for servers, computers, and medical devices.
Advanced digital paralleling technology allows capacity expansion or N+1 redundancy, while ECO mode efficiency exceeds 98%, significantly reducing operational energy costs.
Intelligent battery management lets you fine-tune charge current and discharge cut-off voltage. The intuitive LCD panel provides real-time access to operating parameters, load status, and diagnostic information. Built-in RS232 port and optional SNMP card enable remote monitoring, while the RG45 port protects network data lines.

Frequently Asked Questions
Does the SDE 1011XT support external batteries?
Yes, the unit does not include an internal battery. It connects via ceramic terminals to an external 16-battery pack with a 192V DC bus, allowing you to scale backup runtime as needed.
What equipment can this UPS protect?
It is designed for single-phase critical loads including servers, network switches, storage systems, workstations, medical instruments, and telecom gear. The pure sine wave output ensures compatibility with both linear and switching power supplies.
How long does it take to recharge the batteries?
Recharge time in the XT series depends on the capacity of the connected battery pack. The intelligent charging algorithm automatically optimizes the charging current to maximize battery lifespan.
