Product Overview 

The Altronix SMP5 is a power supply/charger board that converts a low voltage AC input into a selectable 6VDC, 12VDC, or 24VDC output. It provides 4A of continuous supply current at 6VDC or 12VDC, and 3A at 24VDC. Designed as a core component for security, access control, and fire systems, this board-only unit includes a built-in battery charger and is engineered to deliver filtered, electronically regulated power to sensitive electronic devices without voltage spikes or noise.
