AD-155B 27.6V 5A 151.55W Enclosed Switching Power Supply - Dual Output UPS Battery Charger with UL Certification for Security Monitoring Systems

UPS battery life and dual battery protection eliminate power outage risks: Built-in UPS functionality allows seamless battery switching during power outages, ensuring 24/7 device operation. Equipped with battery low-voltage protection (preventing over-discharge) and polarity protection (preventing reverse connection), it supports 24V battery float charging (27.6V main output).
Wide input range and highly stable output, resistant to fluctuations and interference: 88-264VAC global power grid compatibility (supports photovoltaic/energy storage DC input), ±0.5% regulation, ±1% voltage accuracy, and 150mVp-p ripple prevent device restarts and signal distortion.
Triple protection and wide temperature and weather resistance adapt to harsh environments: Short-circuit, overload, and overvoltage protection prevent faults. A wide operating temperature range of -10~+60°C and free air cooling ensure stable operation outdoors and in high-temperature workshops, reducing maintenance costs.
84% High Efficiency + Ultra-Long Lifespan Reduces Long-Term Costs: With up to 84% conversion efficiency, it saves energy and electricity. Full-load burn-in testing yields a mean time between failures (MTBF) of up to 1,818,300 hours, and a two-year warranty reduces repair hassles.
International safety standards + compact portability for easy and compliant installation: UL/TUV/EAC certified, with a leakage current of < 1mA (anti-electric shock protection). Its compact size of 199×110×50mm makes it suitable for surveillance, emergency lighting, industrial control cabinets, and other applications.
