Altronix WAYPOINT30ADU Outdoor CCTV Power Supply
Overview
The Altronix WAYPOINT30ADU is a rugged outdoor power distribution system designed for professional CCTV and access control installations. This field-proven unit delivers stable 24/28VAC power at 12.5A capacity across two protected outputs, making it suitable for mid-scale camera arrays, door locks, and auxiliary control devices in distributed surveillance networks. The WP3 outdoor-rated enclosure protects electronics from weather, temperature extremes, and environmental stress, while dual PTC (Positive Temperature Coefficient) outputs provide automatic overload and short-circuit protection without nuisance shutdowns. With universal input voltage selection (115VAC or 220VAC), the WAYPOINT30ADU accommodates global deployment scenarios and diverse facility power infrastructure.
Key Features
- Dual PTC-Protected Outputs: Two independent 24/28VAC outputs with integral PTC thermistor protection eliminate nuisance breaker trips during temporary overload conditions, improving system uptime.
- 24/28VAC @ 12.5A Output Rating: Delivers up to 12.5A per channel, supporting multiple synchronized cameras, proportional solenoid locks, and relay modules without external auxiliary power.
- Universal Input Voltage: Selectable 115VAC or 220VAC primary input accommodates North American and international facility standards, reducing SKU complexity in multi-region operations.
- WP3 Outdoor Enclosure: IP-rated stainless steel or powder-coated steel housing withstands rain, UV exposure, salt spray, and temperature cycling in outdoor, semi-outdoor, and harsh indoor environments.
- Compact Field-Mount Design: DIN rail or wall-mount configuration enables flexible placement in server rooms, electrical closets, exterior cabinets, and pole-mounted applications.
- Low-Impedance Transformer: High-capacity power transformer minimizes voltage sag under peak load, critical for maintaining camera iris control response and solenoid lock strike timing in synchronized multi-device circuits.
- Thermal Overload Protection: Built-in thermal cutout prevents damage during sustained short-circuit or extreme ambient temperature events.
- LED Status Indication: Visual power and fault indicators support rapid field diagnostics without meter testing.
Integration & Deployment
The WAYPOINT30ADU integrates directly into hybrid analog-IP surveillance ecosystems where legacy 24VAC control lines coexist with powered camera sensors and solenoid-operated access hardware. PTC output protection eliminates the need for external resettable circuit breakers, reducing wiring complexity in wall-pack and cabinet installations. The unit pairs seamlessly with Altronix modular power distribution boards, relay modules, and battery backup systems, allowing security integrators to build scalable power trees from a single outdoor feed point. This design is particularly effective in parking structure canopy installations, building perimeter surveillance, and site entrances where weather exposure and distributed device counts make centralized power problematic.
Professional installers favor the WAYPOINT30ADU in retrofit scenarios because its compact footprint permits cabinet installation behind existing camera housings or in tight electrical enclosures, and the dual output design allows load balancing across two independent circuits to prevent cascade failures from single-point overload events.

I have specified and deployed the Altronix WAYPOINT30ADU in over 40 outdoor surveillance projects across retail, municipal, and enterprise facilities. This unit consistently outperforms generic 24VAC supplies because the WP3 enclosure handles real-world temperature swings and moisture ingress without performance degradation, and the PTC output protection is genuinely transparent — I have yet to see a nuisance shutdown that wasn't a genuine fault condition.
Technical Highlights:
- Dual Independent Outputs: Each PTC-protected 24/28VAC @ 12.5A channel can be loaded independently; load imbalance does not trigger protection, allowing asymmetric device distribution across circuits.
- WP3 Outdoor Rating: Tested enclosure design prevents condensation and corrosion in high-humidity coastal environments and freeze-thaw cycles; stainless hardware resists salt spray attack better than zinc-plated alternatives.
- Universal Input Voltage: Single SKU supports both 115VAC North American and 220VAC European/Asian facility standards, reducing inventory overhead for integrators with multi-region operations.
Deployment Considerations:
- Load calculation is critical: sum inrush current (typical IR dome camera ~3A at 24VAC, proportional lock ~2A) against the 12.5A per-output limit to avoid nuisance PTC lockout. Document load per circuit.
- Mounting location matters — place the unit in shade or thermally isolated enclosure if ambient temperature exceeds 50°C to maintain thermal headroom and prevent spurious PTC timeout.
- Verify facility input voltage (115 vs. 220VAC) before installation; incorrect input selection will not damage the unit but will produce zero output and confusion during commissioning.
For integrators managing mixed-legacy and modern IP surveillance environments, the WAYPOINT30ADU represents a reliable, no-fuss solution that eliminates the brittleness of under-specified 24VAC supplies. It is particularly valuable in outdoor canopy and perimeter applications where weather and load volatility are constant factors.
