ATTE AUPS-40-120-OF Buffer Power Supply SMPS 12V 3.5A 40W

The ATTE AUPS-40-120-OF is a buffer SMPS power supply designed for CCTV, access control, and alarm systems. It provides uninterrupted power during mains outages, with a long backup time compared to classic UPS solutions. The high efficiency (92%) reduces energy consumption and heat buildup.

• Output voltage: 10.8–13.8 VDC, continuous current 3.5 A (max 5 A)
• Fast battery charging up to 1.5 A for gel/AGM 12V batteries
• Protections: SCP, OLP, OHP, overvoltage, battery UVP, reverse polarity
• Technical outputs OUF and ACF for system integration
• Open-frame design for easy mounting in ABOX enclosures or on mounting plates with 10.8 mm raster

Use with optional ASUC converter for higher voltages (24/48/55 VDC) or AVC/AVIC stabilizer for sensitive loads like NVRs and NAS drives. Expand outputs with AF-P8-00-OF fuse module.
