Uninterruptible Power Supply Eaton 3S Mini

The Eaton 3S Mini UPS provides compact, continuous power protection for small electronic devices. Designed for space-constrained workstations, network devices and home office setups, this unit delivers 36 W of output power and accepts input voltages from 90 to 264 V. The integrated lithium battery (4.4 Ah, 3.7 V) supplies backup power during outages and the device is certified to IEC 62477-1 and IEC 62040-2 safety standards.

Advantages

The Eaton 3S Mini combines a very small footprint with reliable battery technology to maintain device operation during short interruptions and controlled shutdowns. Its lightweight construction (0.4 kg) and availability in white or black make it easy to position in different environments without adding significant bulk. Compliance with international safety standards ensures consistent performance and reduced risk to connected equipment.

How to use

Place the Eaton 3S Mini on a stable, flat surface near the equipment to be protected. Connect the UPS input to a reliable AC power source within the specified voltage range, then plug the protected device into the UPS output. Monitor the battery status through any provided indicator on the unit and follow the manufacturer's instructions for initial charging before first use. In the event of a power interruption, the UPS will supply backup power to allow continued operation or a controlled shutdown of connected equipment.

Usage recommendations

Use this UPS for low-power devices that require short-term backup or graceful shutdown capability. Avoid connecting loads that exceed the 36 W output rating. For critical systems requiring longer autonomy or higher power, consider a UPS with higher capacity. Store and operate the unit in a dry, ventilated area and replace the battery according to the manufacturer's guidance.
