Keep low-voltage security systems running with the Altronix OLS120 power supply and charger board. Designed for 12/24 VDC applications, it provides 4 A output in a format that supports both power delivery and charging functions within a single installation platform. That matters in environments where uptime is tied to how cleanly the power subsystem is built. By combining supply and charger board functionality, the OLS120 helps reduce the number of separate components in the enclosure, which can simplify layout, service, and future expansion. For integrators, that translates into a more disciplined installation and fewer points of failure. This model is a practical fit for access control, alarm, and other security deployments that need controlled DC power rather than a generic adapter. It is the kind of component selected when the system design calls for stable output, battery-backed operation, and hardware that belongs in a professional panel. For teams comparing options, the value is in the integration: fewer loose parts, cleaner wiring, and a power architecture built for real installations.
