AEC IST3J-2-4X9 is a single-phase online double-conversion UPS designed to provide stable power to equipment with a capacity of up to 2000VA/2000W. The model is in a 19” rack format (2U) and is equipped with built-in 4 × 12V 9Ah batteries. It is ideal for server racks, communication systems, medical equipment, and locations with high demands for power reliability.
UPS units are available in models with internal batteries or in combination with external battery cabinets for extended runtime.
Rack-mounted UPSs offer numerous advantages, including significant energy savings, as a power factor of 1.0 ensures better load capacity for the same power output, with lower and more affordable initial investment costs.
In addition, very high AC efficiency and accurate and correct data processing are guaranteed thanks to the DSP digital control method.
The double-conversion UPS guarantees a high input power factor of ≥ 0.996 and THDi < 3%, with lower energy pollution and a lower total cost of ownership.
The compact size of the rack-mount UPS and the dust-proof front panel with an LCD display ensure easy installation and a convenient, user-friendly graphical interface to enhance the user experience.
The LCD display can be rotated and positioned horizontally or vertically.
