Technical Highlights
The TechSay SDE 1000XT employs online double-conversion architecture, providing complete isolation from utility power and delivering pure sine wave output with voltage THD under 2% for linear loads.
With an output power factor of 0.9 and 900W capacity, it powers sensitive equipment reliably while handling overloads up to 150% for 300 milliseconds.
The wide input voltage range ensures continuous operation at full load with voltages as low as 176V, and at half load with voltages as low as 110V, maintaining stable output power.
