Information about MEAN WELL AD-155A

Serving as a specialized single-output AC/DC power supply, the MEAN WELL AD-155A integrates an essential UPS function to maintain continuous system operations during unexpected main power interruptions[cite: 1]. Beyond supplying primary DC voltage via Channel 1, it includes a secondary charging channel specifically built for backup batteries, complete with output voltage adjustment capabilities up to 14.5 V[cite: 1]. High operational efficiency is complemented by an active PFC function that ensures compliance with strict power factor guidelines, while safety mechanisms like low battery disconnect safeguard connected battery banks[cite: 1]. Fully compliant with standard UL62368-1 requirements, this model is particularly suitable for security systems, emergency lighting, and critical monitoring gear where reliable power fallback is mandatory[cite: 1].
