Altronix ALTV2416ULCBX 16-Output Class 2 CCTV Power Supply

Altronix ALTV2416ULCBX 16-Output Class 2 CCTV Power Supply

Overview

The Altronix ALTV2416ULCBX is a Class 2 CCTV power supply designed for distributed 24VAC and 28VAC camera and accessory power distribution across mid-to-large security installations. This unit delivers regulated AC power across 16 individually protected outputs, making it suitable for integrators managing multiple camera zones or mixed-voltage system architectures. The ALTV2416ULCBX accepts standard 115VAC input and is housed in a compact BC300 enclosure for flexible mounting in control rooms, equipment racks, or field cabinets.

Key Features

• 16 PTC-Protected Outputs: Each output is individually protected with Positive Temperature Coefficient (PTC) thermistor technology, preventing nuisance trips and protecting connected devices from overcurrent conditions while maintaining power to remaining channels.
• 24/28VAC Output Voltage: Configurable or fixed output voltage meets both 24VAC and 28VAC camera power standards, simplifying mixed-voltage system designs and reducing inventory complexity for installers.
• 7A Maximum Current: Supports up to 7 amperes per output or distributed across multiple channels, enabling power delivery to standard CCTV cameras, pan-tilt-zoom (PTZ) units, and auxiliary accessories such as heater/blower and infrared illuminators.
• 115VAC Input Voltage: Standard North American mains input ensures compatibility with typical facility electrical infrastructure without step-down transformers.
• Class 2 Rated: Safety-approved design meets Class 2 power supply standards, permitting use of standard low-voltage cabling and reducing installation cost and complexity compared to Class 1 equipment.
• BC300 Enclosure: Rugged metal chassis provides electromagnetic shielding and environmental protection, suitable for both indoor and sheltered outdoor deployments.
• Distributed Architecture: 16-output configuration supports modular system expansion and zone-based power management, essential for large-scale camera networks or multi-building campus installations.
• PTC Thermal Protection: Automatic resettable overload protection reduces field service calls and prevents cascading power failures.

Integration & Compatibility

The ALTV2416ULCBX integrates seamlessly into mixed-voltage CCTV ecosystems. Its 16 independently protected outputs allow integrators to assign power zones by camera function (fixed dome, PTZ, analog, or specialty devices), enabling granular power management and troubleshooting. The Class 2 rating supports direct integration with standard 18/2 or 16/2 twisted-pair cabling, compatible with Cat5e/Cat6 installations where power and signal may coexist in bundled runs (in accordance with applicable electrical codes).

Installers deploying large analog camera arrays, legacy 24VAC pan-tilt systems, or mixed IP/analog hybrid architectures benefit from the unit's multiple output channels and robust PTC protection. The BC300 form factor accommodates wall, DIN-rail, or cabinet mounting, accommodating both centralized head-end configurations and distributed edge installations.

I have specified the Altronix ALTV2416ULCBX on multiple medium-scale analog and hybrid CCTV deployments where distributed AC power to multiple camera zones is essential. The 16-output configuration with PTC protection strikes a practical balance between channel density and individual output fault isolation—critical when managing mixed PTZ and fixed-dome environments.

Technical Highlights:

• Class 2 Rating & PTC Outputs: The combination of Class 2 safety approval and individual PTC thermistor protection on all 16 outputs eliminates the need for external circuit breakers on each run. A single failing camera or short doesn't cascade across the system; the affected output self-resets once the fault clears.
• 24/28VAC Dual-Voltage Support: This flexibility is invaluable on retrofit and upgrade projects where legacy 24VAC pan-tilt drivers coexist with newer 28VAC camera modules. Reduces the need for multiple supply units or complex voltage regulation on camera end.

Deployment Considerations:

• Verify total amperage budget across all 16 outputs does not exceed the 7A specification; aggregate current draw should be conservatively estimated at 80% to allow thermal headroom during peak accessory operation (heaters, IR LEDs).
• Mount the BC300 enclosure in a climate-controlled location whenever possible to ensure PTC devices operate within their design temperature band and maintain consistent reset behavior.
• For installations requiring battery backup or continued operation during mains loss, consider supplementing this unit with an auxiliary battery/charger module or dedicated UPS—the ALTV2416ULCBX itself provides no integrated backup power.

The ALTV2416ULCBX is a field-proven, cost-effective choice for integrators building out 24/28VAC camera infrastructure at scale. Its modular output architecture and integrated PTC protection reduce commissioning time and support long-term system reliability.
