Altronix WPTV244175UL 4-Output Outdoor CCTV Power Supply

Altronix WPTV244175UL Outdoor CCTV Power Supply

Overview

The Altronix WPTV244175UL is a weatherproof outdoor power supply designed for distributed CCTV and security camera installations requiring reliable AC-to-AC voltage conversion and protection. Built for permanent outdoor mounting, the WPTV244175UL delivers 24/28VAC at up to 7 amps across four separate outputs, with integrated overcurrent protection and a rugged enclosure rated for environmental exposure. This unit is purpose-built for integrators and installers who need a compact, field-proven solution for powering multiple camera runs or auxiliary security loads without indoor infrastructure.

Key Features

• Dual Output Configuration: One fused output and three PTC-protected outputs provide flexible circuit segregation and prevent nuisance shutdowns from transient overloads
• 24/28VAC Output @ 7A: Delivers sufficient amperage for multiple camera feeds or mixed analog and IP camera loads across separate circuits
• 115VAC Input: Standard North American mains voltage compatibility; transformer-isolated design protects downstream equipment
• Weatherproof WP1 Enclosure: Rated for outdoor wall mounting with dimensions of 12" H x 8" W x 6" D; compact form factor fits tight mounting locations while maintaining thermal management
• PTC Overcurrent Protection: Three outputs use positive temperature coefficient (PTC) self-resetting protection; eliminates manual fuse replacement and reduces service callbacks for minor faults
• Fused Primary Output: One user-replaceable fused circuit for mission-critical loads or legacy systems requiring traditional fusing
• UL Listed & CE Approved: Meets North American and European safety standards for permanent outdoor installation
• Transformer-Isolated Design: Provides galvanic isolation between input and output, reducing ground-loop hum and protecting connected cameras from mains surge transients

Integration & Compatibility

The WPTV244175UL is platform-agnostic and works with analog CCTV cameras, IP megapixel cameras, DVRs, NVRs, and auxiliary security devices (access control, intercoms, sensors) requiring 24VAC power. The four-output design allows installers to segregate circuits by camera zone, building wing, or load type—reducing the impact of a single circuit fault on the entire installation. PTC protection on three outputs provides automatic recovery without technician intervention, while the fused output accommodates systems requiring hard isolation. Output voltage can be adjusted within the 24/28VAC range to match camera specifications and cable run compensation requirements.

Physical Specifications

Enclosure dimensions: 12" H x 8" W x 6" D. Designed for outdoor wall, pole, or bracket mounting. The weatherproof housing protects internal transformer and terminal blocks from rain, UV, temperature cycling, and dust ingress typical in uncontrolled outdoor environments.

James Everett

The Altronix WPTV244175UL is a solid workhorse for distributed outdoor camera systems where centralized power infrastructure is impractical. During recent deployments, I've found the combination of transformer isolation and mixed protection (fused + PTC) to be tactically sound: you get both redundancy and simplicity without over-engineering the circuit topology.

Technical Highlights:

• Output Separation: The fused circuit isolates one critical load, while three PTC-protected circuits self-recover from nuisance trips—reducing site visits and downtime
• Compact Outdoor Form Factor: 12" × 8" × 6" enclosure fits standard utility boxes and doesn't create mounting headaches on small walls or poles
• Transformer Isolation: Input-to-output galvanic isolation is essential in ground-loop-prone environments; the WPTV244175UL includes this by design
• UL/CE Compliance: Permitting and insurance pre-approvals are non-negotiable in commercial installs; this unit clears both regulatory hurdles

Deployment Considerations:

• Verify local building codes for outdoor electrical box grounding and bonding requirements before wall mounting
• Plan circuit loading carefully: 7A total budget divided across four outputs means each output handles approximately 1.75A average, accounting for inrush current during camera startup
• Use this supply in conjunction with surge suppression on the mains input if the installation sits in a lightning-prone area or near industrial loads

The WPTV244175UL remains a reliable choice for mid-scale outdoor systems. It won't solve every power architecture challenge, but for straightforward multi-camera sites that lack central plant, it delivers dependable performance at a rational price point.
