Altronix SAV9D 9-Output 12VDC CCTV Power Supply
The Altronix SAV9D is a regulated 12VDC power distribution unit purpose-built for small to medium surveillance installations where multiple cameras and access control devices share a common power backbone. This compact unit supplies 6 amps maximum across nine independently protected circuits, making it suitable for distributed camera arrays, door readers, and auxiliary surveillance hardware that cannot draw power directly from a networked source.
Key Features
- 9 PTC-Protected Outputs: Each circuit includes Positive Temperature Coefficient protection, which means individual load faults (short circuits, overload) will trip only that single output without cascading to the remaining eight — a critical safeguard when a single failed camera or accessory could otherwise take down your entire distribution. This isolation keeps the rest of your surveillance infrastructure alive while you diagnose and replace the failed device.
- 12VDC Regulated Output: Stable, regulated 12 volts ensures cameras, access control readers, and auxiliary devices receive consistent power within their operating tolerance, reducing flicker, color shift, and dropout risk across multi-hour recording sessions.
- 6 Amp Maximum Capacity: Total available current allows for a realistic mix of camera power draws — typically three to five mid-range bullet or turret cameras plus one to two access control devices, depending on individual wattage ratings. Not all nine outputs will draw maximum simultaneously in most real deployments, but you must account for peak concurrent demand when sizing.
- 230VAC Input: Operates on standard European and international AC mains, so regional availability and electrical standards in your jurisdiction matter — confirm AC supply before purchase.
- Compact BC100 Enclosure: Wall-mountable or rack-adjacent form factor minimizes footprint in utility closets or equipment cabinets, important when space is already tight in retrofit surveillance projects.
- UL Listed Construction: Meets North American safety standards, required for most commercial installations and often a contractual prerequisite for system integrators and end-user procurement.
- Lifetime Limited Warranty: Manufacturer covers defects for the product lifetime, though this is contingent on proper installation and use within rated electrical parameters — read the full warranty terms before relying on this as your sole backup power strategy.
Integration & Compatibility
The SAV9D pairs with analog and IP surveillance systems alike. Any 12VDC camera, dome drive motor, door reader, or access control module rated within the 6-amp aggregate and individual PTC limits will connect directly. If you are planning a network video recorder installation, keep in mind that the SAV9D supplies power to cameras and peripherals, not the recorder itself — the recorder typically draws 110–240VAC or operates via managed network switches with PoE capabilities.
In hybrid deployments mixing legacy analog cameras with modern IP devices, the SAV9D handles the analog power distribution while PoE injectors or switches manage IP camera provisioning. This separation of power domains is cleaner than cramming both into one supply and reduces fault propagation.
Deployment Considerations
Before installation, calculate actual current draw from your camera datasheets and add 20% margin for in-rush transient peaks during startup. A single 12VDC camera might draw 0.5 to 1.2 amps; nine devices drawing an average of 0.67 amps each hits your 6-amp ceiling exactly. Oversubscription is possible if you load without measurement — PTC protection will prevent fire or damage but will also prevent cameras from powering on, leaving you without visibility during the critical moment you discover the issue.
Wiring distance matters. Run thicker gauge copper (10 AWG or better) for runs exceeding 50 feet to compensate for voltage drop — thin wire over long distance will starve cameras of the full 12 volts, causing image dropout or noise even though the supply is compliant.
When to Choose a Different Model
If you need more than 6 amps or more than nine outputs, look for larger Altronix regulated supplies in the SAV series — the SAV16D and SAV24 offer 16 and 24 outputs respectively. If your installation is exclusively modern IP cameras powered by PoE, this supply becomes redundant. If you require battery backup or UPS functionality, the SAV9D provides none — you would need an uninterruptible power supply rated for 12VDC downstream, or consider a separate battery-backed power module in the Altronix portfolio.

The Altronix SAV9D is straightforward infrastructure — a reliable 12VDC backbone for analog camera arrays and mixed legacy/IP hybrid systems. At 6 amps and nine circuits, it sits in a practical sweet spot: large enough for a typical small-to-medium retail or light industrial install, but not so large that you overspecify and waste capacity. The PTC isolation on each output is the key technical feature that separates this from a dumb power brick; it means a single shorted camera or accessory won't black out your entire surveillance network.
Technical Highlights:
- 9 PTC-Protected Circuits: Individual circuit protection ensures a single load fault does not cascade to the remaining eight outputs. In a nine-camera deployment, you retain visibility on eight cameras even if one suffers a wiring short or device failure — critical for security continuity.
- 6 Amp Aggregate Capacity: Realistic for three to five mid-range bullet cameras (0.5–1.2A each) plus one or two access control readers (0.3–0.8A each). Oversubscription without load measurement is the most common mistake — always verify manufacturer current draw before commissioning.
- 230VAC Mains Input: Requires standard European AC supply. Confirm availability and electrical code compliance in your region before procurement — this is not a 110V or dual-voltage unit.
Deployment Considerations:
- Voltage drop over long cable runs (beyond 50 feet) is a real issue with 12VDC distribution. Use heavier gauge copper (10 AWG or better) to avoid starving cameras of the full 12V — undersized wire will cause intermittent dropouts and noise, especially on startup transients.
- The SAV9D provides no battery backup or UPS capability. If you need ride-through during mains loss, you must add a separate 12VDC battery backup or UPS downstream. This is a power distribution device, not an emergency power solution.
Best fit: retrofit analog CCTV networks, small to medium retail or warehouse surveillance, and hybrid deployments where legacy analog cameras coexist with newer IP devices. Avoid it if you are going 100% PoE IP — modern cameras don't need 12VDC, and a managed PoE switch is simpler and more efficient.
