FAQ
What is the Mean Well ES-SU3K-TH used for?
The ES-SU3K-TH is an uninterruptible online UPS designed for applications that need stable AC backup power. It is suited to commercial and industrial environments where power quality, continuity, and broad input tolerance are important.
What power capacity does the ES-SU3K-TH provide?
This model is rated for 3KVA / 3KW output. It also has an output power factor of 1, which means its kVA and kW ratings are matched for full real-power delivery.
What input voltage range does the ES-SU3K-TH support?
The ES-SU3K-TH supports an ultra-wide AC input range of 110V to 300Vac based on load at 50%, and 160V to 300Vac based on load at 100%. This wide range helps it handle challenging mains conditions more effectively than narrower-input models.
Can the ES-SU3K-TH work in sites that use fuel generators?
Yes. Mean Well lists support for connection to fuel generators as one of the product features. That makes this model relevant for facilities where backup generation is part of the power strategy.
What output voltages are available on the ES-SU3K-TH?
The ES-SU3K-TH supports selectable output voltages of 200, 208, 220, 230, and 240Vac. It also includes a 50Hz/60Hz frequency conversion mode for applications that need power-format flexibility.
How does the ES-SU3K-TH help with power quality?
This UPS is specified with input power factor of at least 0.99 and input current harmonic distortion of 5% or less. On the output side, harmonic distortion is rated at 2% THD for linear loads and 5% THD for non-linear loads.
What monitoring and control features does the ES-SU3K-TH include?
The unit includes an LCD display panel plus USB and RS-232 communication interfaces. It also provides an emergency power-off function and intelligent charging mode with charging current selectable at 1, 2, 4, 6 or 8A through the LCD.
What operating environment and warranty apply to the ES-SU3K-TH?
The specified operating temperature range is 0°C to 40°C. Mean Well also lists a 3-year warranty for this model.
