Altronix SMP7CTX220 Cabinet Power Supply with Battery Backup, 6A 12/24VDC 220V Input

Overview

The Altronix SMP7CTX220 is a cabinet-mounted, battery-backed power supply engineered for international security system deployments where the local mains voltage runs at 220VAC. Outputting up to 6A at either 12VDC or 24VDC — selectable to match your field devices — the SMP7CTX220 brings the reliability and enclosure convenience that integrators expect from the Altronix power supply line to 50/60Hz international grid environments. If you're sourcing surveillance power supplies for a European, Latin American, or Middle Eastern deployment and need a self-contained, cabinet-ready solution with built-in battery backup, this unit belongs on your shortlist.

Key Features

• 220VAC Input with Wide Tolerance (198–256VAC): The SMP7CTX220 accepts anything from 198VAC to 256VAC, which means it handles the real-world voltage fluctuations common on international power grids without tripping or over-stressing the transformer. That's a meaningful operational buffer on sites where supply quality isn't consistent.
• Selectable 12VDC or 24VDC Output: Rather than stocking separate SKUs for different device voltages, you configure the output on-site. 12VDC serves the majority of IP cameras and access readers; 24VDC suits PTZ motors, intercoms, and certain legacy analog devices. One unit covers both scenarios — check your device requirements before configuring the output.
• 6A Total Output with Fused and PTC Protection: Total output is split across a 3.5A fused circuit and a 2.5A PTC (self-resetting) circuit. The fused leg protects against sustained overcurrent; the PTC leg recovers automatically after a brief overload without requiring a field visit to swap a fuse. This two-circuit architecture lets you segment critical devices from non-critical loads directly at the power supply.
• Battery Backup Support — 7AH or 12AH: The cabinet accommodates sealed lead acid or gel-type batteries up to 12AH/12VDC, giving you the option to tailor standby runtime to site requirements. For a security power planning exercise, a 7AH battery typically delivers several hours of backup for a lightly loaded access control panel; a 12AH battery extends that headroom substantially for higher-draw configurations.
• CE Agency Listing: CE certification is a hard requirement for equipment sold or installed across the European Economic Area. The SMP7CTX220 carries CE listing, which clears the regulatory path for EU and EEA deployments without requiring additional compliance work on your end.
• Low BTU Output: Heat dissipation is 37 BTU/Hr at 12VDC and 74 BTU/Hr at 24VDC — low enough that thermal load inside the cabinet won't drive a need for active cooling on most installations. Factor this into your enclosure sizing if you're stacking multiple power supplies in a shared panel.
