AD-155B 27.6V 5A UPS Switching Power Supply - 155W Battery Charger with Dual Output, 88-264VAC Input, UL/TUV Certified for Security CCTV, Communication, Emergency Lighting (24V Battery Backup)

Industrial-grade durability and UPS power outage resistance ensure seamless safety: Supporting a wide operating temperature range of -10°C to +60°C, 2G shock resistance, and UL/TUV certification, it switches to battery power within 24ms after a power outage. Low-battery voltage protection prevents surveillance recording and equipment emergency shutdown
Precise 27.6V voltage regulation and 151.55W full power output effectively prevent device failures: Main output voltage accuracy is ±1%, line/load regulation is ±0.5%, and the 5A rated current is suitable for 24-29V devices, effectively eliminating issues such as undervoltage, black screen, insufficient power, and device burnout
Dual output and series compatibility: The main output is 27.6V/5A (for core devices) and the auxiliary output is 27.1V/0.5A (for auxiliary devices), eliminating the need for a separate power supply. It directly replaces the older AD-155 series 27.6V power supply, saving wiring and maintenance costs
Low-voltage safety, high energy efficiency, and durability: The safe 27.6V low-voltage design eliminates the risk of electric shock for non-professional installers. Full-load efficiency reaches 84%, with a mean time between failures (MTBF) of approximately 26 years. In industrial scenarios, it can operate maintenance-free for three years, effectively reducing electricity and repair costs
Individually packaged, ready for installation, eliminating small-batch waste: Individually packaged, each unit can be purchased separately, eliminating unused packaging boxes. Each unit undergoes full-load burn-in testing and is ready for immediate installation, making it suitable for maintenance and small-batch monitoring projects, reducing procurement and trial-and-error costs
