Keep critical access control hardware powered with a supply designed for multi-device distribution. The Altronix MAXIMAL33D delivers 12 VDC at 6 A or 24 VDC at 6 A, giving integrators flexibility when standardizing around mixed-voltage field devices. With 16 PTC-protected outputs, it helps isolate faults at the branch level instead of taking down an entire run. That matters in real deployments where readers, locks, request-to-exit devices, and auxiliary modules all depend on clean, predictable power. The protected output architecture supports faster troubleshooting and better uptime, especially in larger openings where downtime is visible and costly. For teams building commercial access systems, this model offers the kind of power distribution density that reduces enclosure clutter and supports cleaner panel layouts. Choose it when you need more than a basic supply. The MAXIMAL33D is suited to installations where reliability, output count, and voltage flexibility directly affect commissioning time and long-term serviceability.
