Unidade de alimentação ininterrupta SATEL APS-412 12 V 4 A, compacta cinzenta, 77×59×122 mm

The SATEL APS-412 is a compact uninterruptible power supply (UPS) designed to provide stable 12 V DC output with a maximum current of 4 A. Housed in a small grey enclosure measuring 77×59×122 mm and weighing 0.306 kg, this UPS is intended for installations where space is limited. It accepts an input voltage of 10.5 V and delivers reliable backup power for small alarm systems, control modules and other low-power electronic devices that require uninterrupted 12 V supply.

Advantages

The compact dimensions and light weight allow installation in cabinets, small enclosures or next to control panels without significant space impact. The unit is engineered to deliver regulated 12 V output at up to 4 A, offering consistent performance for connected devices. Its simple design and neutral grey finish make it suitable for discreet integration into various installations. The APS-412 provides a practical solution for maintaining power to essential low-current electronics during mains interruptions or unstable input conditions.

How to use

Install the UPS in a dry, ventilated location close to the device or control panel to be powered. Connect the input supply according to the installer instructions and ensure polarity is correct before switching on. Connect the 12 V output to the device(s) requiring backup power, observing current limits so the combined load does not exceed 4 A. Verify output voltage under load and confirm proper operation of the connected equipment. Periodically inspect connections and enclosure for signs of wear or overheating.

Recommendations

For reliable operation, avoid exposing the unit to excessive heat, moisture or dust. Ensure the total connected load remains within the 4 A rating and allow adequate airflow around the enclosure. Use appropriate cable cross-sections and secure terminals to minimize voltage drop. For installations in security or safety systems, follow local regulations and manufacturer guidance for backup power wiring and testing intervals.
