EATON UPS 3S 450 DIN Gen2

The EATON UPS 3S 450 DIN Gen 2 uninterruptible power supply operates with off-line topology, providing an apparent power of 450VA and a real power of 270W. This UPS protects home electronics and office computers. At full load, it powers connected devices for 1.67 minutes; at half load, this time extends to 6.5 minutes. Its compact body, measuring 835 × 140 × 325mm, houses all the electronics. The tower design and 2.9kg weight make it easy to install and place on or next to a desk. With a low noise level of under 25dB, it won't disturb you while you work or relax.

Performance and operating parameters

The EATON UPS 3S 450 DIN Gen 2 uninterruptible power supply uses off-line topology with an output power factor of 0.6. It operates with a default input and output voltage of 230V, which can be set to 220V or 240V. The standard input voltage range is 184–264V, which can be extended to 161–284V via software adjustment. The device automatically detects the nominal frequency of 50/60Hz and operates within the 46–70Hz range. These parameters protect sensitive electronics from mains fluctuations. A low operating noise level of under 25dB, measured from one metre, ensures quiet operation.

Battery management and protection

Inside the EATON UPS 3S 450 DIN Gen 2 uninterruptible power supply is a sealed 12V/4.5Ah lead-acid battery, which the user can replace if needed. Intelligent battery management includes several key features. An automatic battery test periodically checks its condition and readiness. Deep-discharge protection extends the battery's lifespan. The cold start function lets you start the device without mains power. In addition, integrated surge protection protects all connected devices from damage caused by voltage spikes.

Eaton UPS Companion software and configuration

The Eaton UPS Companion software is used for advanced management and monitoring of the EATON UPS 3S 450 DIN Gen 2 uninterruptible power supply. The application handles the safe shutdown of a connected computer in the event of a prolonged power outage, preventing the loss of unsaved data. It also provides clear energy consumption measurements, which helps to monitor running costs. In the software interface, you can configure advanced UPS settings, such as voltage thresholds or sensitivity. An auto-shutdown feature for effective power management is also included.

Connectivity and sockets

The EATON UPS 3S 450 DIN Gen 2 uninterruptible power supply connects to the mains via an input cable with a Schuko plug. It offers a total of six Schuko sockets on its output. Three of them are fully backed up by the battery and are intended for powering critical devices like a computer or monitor. The remaining three sockets provide surge protection only and are suitable for connecting peripherals that do not require battery backup, such as a printer or speakers.
