Information about the MEAN WELL ADD-155C

The MEAN WELL ADD-155C is a specialized 155W triple-output power supply designed specifically for 48V-based Uninterruptible Power Supply (UPS) applications. This model is distinguished by its high-voltage 54V primary output and a dedicated 53.5V battery charging channel, complemented by a 5V rail for auxiliary logic or control circuits. By incorporating a built-in active PFC function, the unit maintains high power efficiency and stability, ensuring that critical security systems or communication hardware remain operational even during primary power failures. The fanless design utilizes natural air convection for cooling, which eliminates mechanical noise and significantly enhances the long-term reliability of the unit in dust-sensitive industrial environments.

Engineered for high-reliability environments, the ADD-155C includes professional-grade safety features such as battery low and battery polarity protections to prevent damage to expensive battery banks. The main 54V output offers a wide adjustment range of 48V to 58V, allowing users to fine-tune the voltage to compensate for line loss or specific battery float requirements. Every unit undergoes a 100% full load burn-in test and is certified to global standards like UL62368-1, making it a robust choice for industrial security cabinets, remote telecommunications, and 48V emergency backup systems that require uninterruptible energy delivery.
