Altronix SMP7PMP16CB220 16-Output PTC Power Supply for Surveillance Systems
Overview
The Altronix SMP7PMP16CB220 is a centralized 220VAC power distribution unit built for multi-camera and multi-device surveillance installations where you need individual per-output fault protection without a rat's nest of individual power adapters. It delivers 12VDC or 24VDC at up to 6A total continuous output across 16 individually PTC-protected circuits — the architecture that lets one device trip without darkening the rest of the system. This is the 220VAC input variant, which makes it the correct choice for installations outside North America or in facilities already wired to IEC/EU power standards.
For integrators building out large analog or hybrid camera runs — access control readers, door strikes, or mixed surveillance loads — the SMP7PMP16CB220 consolidates power into a single enclosure that fits in a structured cabling cabinet or dedicated power rack space.
Key Features
- 220VAC Input: Accepts international mains voltage, making this the right power supply for EU, Middle East, Asian, and other 220V-standard facilities. No step-down transformer needed — wire directly to local mains.
- 12VDC / 24VDC Selectable Output: Dual-voltage flexibility lets you serve both 12V analog cameras and 24V access control hardware from the same unit without separate power supplies. Select the output voltage at configuration time to match your device mix.
- 6A Total Output Current: At 6A, this unit can realistically power 12–16 low-current cameras or readers in a typical deployment. Budget roughly 300–500mA per analog camera — at that draw, the 6A rail supports 12–20 devices before you hit the ceiling. Know your load before you wire.
- 16 Individually PTC-Protected Outputs: Positive Temperature Coefficient (PTC) protection on every output means a shorted or overloaded run self-limits and auto-resets once the fault clears — no fuses to pull, no service call to reset. A single failing device does not cascade to adjacent circuits.
- Centralized Distribution Architecture: All 16 outputs from a single chassis simplify commissioning, troubleshooting, and future adds. Technicians can measure each output independently at one location rather than hunting down 16 wall warts across a ceiling grid.
- Compact Footprint — 3.25 × 13.00 × 13.50 in: At just over 13 inches on its longest edge, this unit fits inside standard Altronix enclosures or purpose-built power cabinets without consuming excessive rack depth.
- 10.6 lb Rated Weight: Substantial enough to indicate a quality transformer core rather than a minimal switching supply, yet manageable for one-person wall or rack installation during rough-in.
Integration and Compatibility
The SMP7PMP16CB220 is designed for use with Altronix's broader Altronix power distribution ecosystem, including compatible enclosures that accept the SMP7 series power supply boards. It is well suited as the power backbone for IP and analog security camera runs, access control readers, and door-strike hardware that operate on 12VDC or 24VDC. When planning a multi-camera installation, pair this unit with a network video recorder and confirm that your aggregate camera draw stays under 6A total — exceeding that figure requires a second supply or a higher-capacity model in the SMP series. For installations where individual camera circuits exceed the PTC trip threshold, verify device inrush current before finalizing the design. This supply is sized for steady-state loads, not high-inrush PTZ or motorized-lens cameras without appropriate sequencing. Integrators planning large-scale camera deployments should also review PoE switch options as a complementary or alternative power distribution strategy for IP cameras.
Frequently Asked Questions
Q: What input voltage does the SMP7PMP16CB220 require?
A: The SMP7PMP16CB220 requires 220VAC input. It is not rated for 110VAC North American mains without a step-up transformer — confirm your facility's mains voltage before ordering.
Q: Can the SMP7PMP16CB220 output both 12VDC and 24VDC simultaneously?
A: No. The unit is selectable between 12VDC and 24VDC but delivers a single output voltage across all 16 outputs. If your installation mixes 12V and 24V devices, you will need separate supplies for each voltage level.
Q: How many cameras can the SMP7PMP16CB220 power?
A: The total output is 6A. At a typical 300–500mA draw per analog camera, you can expect to power 12–20 devices — but you must calculate your actual aggregate load including inrush before finalizing the design. Do not exceed 6A total across all 16 outputs.
Q: What happens if one camera circuit shorts or draws too much current?
A: Each of the 16 outputs is protected by a PTC (Positive Temperature Coefficient) device. A faulted output self-limits and automatically resets after the fault is cleared — no fuse replacement required, and adjacent outputs remain unaffected.
Q: What enclosure does the SMP7PMP16CB220 fit in?
A: The SMP7PMP16CB220 is part of the Altronix SMP7 series and is compatible with Altronix enclosures designed for the SMP7 power supply board. Verify enclosure compatibility with Altronix documentation before purchasing an enclosure separately.
Q: What are the physical dimensions and weight of the SMP7PMP16CB220?
A: The unit measures 3.25 × 13.00 × 13.50 inches and weighs 10.6 lbs.
The SMP7PMP16CB220 is built around one spec that matters most in multi-camera deployments: 16 individually PTC-protected outputs on a single 6A, 220VAC-input rail. That combination means you can centralize power distribution for an entire camera wing or access control zone without the fault-cascade risk that comes from a shared fuse rail. I reach for this unit specifically when the job site is on 220V mains and the device count is high enough that per-device power adapters become a maintenance liability.
Technical Highlights:
- 220VAC Input: Directly compatible with IEC/EU and international 220V mains — no transformer overhead, no additional hardware cost, no voltage conversion loss to account for in your power budget.
- 16 PTC-Protected Outputs: Auto-resetting PTC protection per output is the operational advantage over fuse-based designs. A shorted camera circuit trips and recovers without a site visit or fuse stock — meaningful when cameras are at height or in hard-to-reach locations.
- 12/24VDC Selectable at 6A: The dual-voltage selection covers the two most common device voltages in analog surveillance and access control. At 6A, you have enough headroom for a full 16-output deployment at nominal camera draws, but this is a shared rail — calculate your load before you wire the last device.
Deployment Considerations:
- Verify aggregate device draw before commissioning. At 6A total across 16 outputs, each output averages only 375mA — fine for standard analog cameras, but any PTZ or motorized-lens camera with higher inrush can consume multiple outputs' worth of headroom.
- The 12/24VDC selection is fixed at installation — if your device mix requires both voltages, plan for a second supply rather than expecting field-switchable per-output voltage control.
This supply is the right call for international hotel, retail chain, or industrial facility rollouts on 220V infrastructure where a 16-zone analog or hybrid camera system needs centralized, fault-tolerant power distribution in a single mountable chassis.
