T-4001 1-In / 1-Out, with built-in battery, (1-10KVA)



The i-power T-4001 series is a true online double-conversion UPS that can provide your critcal equipment with reliable and stable sine wave power. It features significant advantages, including an output power factor up to 0.9 and up to 90% AC-AC efficiency for greater energy savings.

It is a versatile, high quality, and cost-competitive UPS developed to handle a wide voltage range and inconsistent power conditions. The T-4001 series provides a safe power supply guaranteed for mission-critical applications such as computer equipment, telecommunication devices, precision instrument, network termination equipment, and more.


Product Highlights:

  • Wide Input Voltage Range allows the UPS to work in harsh environments and reduces battery discharging time.
  • GBT technology to achieve high overall efficiency up to 90%.
  • High input power factor (0.99) and low harmonic distortion (THDI 5%) saves upstream investment.
  • Can be connected with all kinds of generators to save customers costs.
  • True online double-conversion topology and zero transfer time to battery provides 24/7 full-time protection.
