Frequently Asked Questions

What applications is the Mean Well ES-SU3K-THB best suited for?

The ES-SU3K-THB is a 3KVA/3KW online UPS designed for applications that need stable AC backup power with battery support. It is suitable for commercial and industrial equipment, including power supply and security-related environments where continuous operation is important.

What is the power capacity of the ES-SU3K-THB?

This model is rated at 3KVA / 3KW, with an output power factor of 1. That means its kVA and kW ratings are matched, which is useful for loads that require full real power output from the UPS.

Can the ES-SU3K-THB work with unstable mains power or generator-backed systems?

Yes. The ES-SU3K-THB supports connection to fuel generators and has an ultra-wide input voltage range of 110V to 300Vac at 50% load, or 160V to 300Vac at 100% load. This makes it a practical option where incoming AC supply conditions may vary.

What output voltage options does the ES-SU3K-THB provide?

The ES-SU3K-THB supports selectable output voltages of 200, 208, 220, 230, and 240Vac. It also includes a 50Hz/60Hz frequency conversion mode, which can help when matching equipment requirements across different power standards.

How can users monitor the ES-SU3K-THB?

This UPS includes an LCD display panel for local status visibility and provides USB and RS-232 communication interfaces. Those features make it easier to monitor operating status and battery-related information for this specific model.

What operating environment is recommended for the ES-SU3K-THB?

The specified operating temperature range for the ES-SU3K-THB is 0°C to 40°C. The unit measures 426 x 190 x 338 mm and weighs 26.2 kg, so buyers should confirm the installation space and ambient conditions are suitable for a UPS of this size.

What battery charging features does the ES-SU3K-THB include?

The ES-SU3K-THB uses an intelligent charging mode with adjustable charging current. The charging current is rated at 8A and can be adjusted through the LCD to 1A, 2A, 4A, 6A, or 8A.
