Altronix WP3 NEMA 4/IP66 Outdoor Power Enclosure
Overview
The Altronix WP3 is a weather-sealed outdoor enclosure built to NEMA 4/IP66 standards for security and infrastructure applications where power supplies, battery backup systems, and distribution electronics must survive uncontrolled outdoor environments. Measuring 13.3 inches high by 11.3 inches wide by 5.6 inches deep, the WP3 delivers a compact footprint suitable for wall-mount or pole-mount deployments without dominating sight lines or requiring extensive site modification. This enclosure integrates with Altronix power supplies to create a protected outdoor power infrastructure backbone.
Key Features
- NEMA 4/IP 66 Rating: Sealed construction withstands direct spray from water jets and prevents dust ingress from any direction—critical in rain, snow, salt spray, and coastal installations where corrosion and moisture ingress would otherwise damage exposed electronics within weeks.
- Compact Dimensions (13.3in H × 11.3in W × 5.6in D): Fits tight spaces and reduces visual footprint in aesthetically sensitive installations like residential perimeters or historic properties, while maintaining sufficient internal volume for power supplies, battery modules, and terminal blocks.
- Corrosion-Resistant Construction: Materials chosen for outdoor durability resist salt spray and industrial pollutants—essential for coastal, industrial, and manufacturing site deployments where untreated steel would require replacement annually.
- Interior Component Accommodation: Designed to house standard Altronix power supplies, battery backup chargers, and distribution terminals, allowing integrators to assemble a complete power management system inside a single sealed unit rather than daisy-chaining separate weatherproof boxes.
- Standard Mounting Provisions: Wall and pole-mount hardware allows installation on building corners, utility poles, or free-standing structures without custom fabrication or site-specific engineering.
- Integration-Ready Design: Pairs directly with Altronix power infrastructure products through standard connector layouts and terminal configurations, reducing assembly time and compatibility risk.
Why NEMA 4/IP66 Matters for Outdoor Deployments
NEMA 4 and IP66 ratings both certify protection against water jets and dust, but security integrators should understand the practical difference: NEMA 4 enclosures resist water spray from any angle and are commonly deployed in outdoor industrial and security settings. IP66 explicitly covers high-pressure jets (like fire hose spray) and is the international equivalent. This dual rating means the WP3 will not corrode, develop condensation, or trap moisture even in humid, salt-spray, or rainy climates. Without this protection, power supplies and battery chargers exposed to the elements typically fail within 6–18 months due to corrosion of circuit board traces and solder joints. The WP3 eliminates this failure mode entirely.
Integration and Deployment Context
Deploy the WP3 where outdoor power distribution must be reliable and maintenance-free: remote access control gate installations, perimeter lighting systems, outdoor camera arrays, and automated gate operators. The enclosure's interior volume accommodates a power supply, battery backup charger, and terminal distribution block, creating a single protected node that feeds 24VDC to multiple cameras or control devices via hardened conduit. Its compact footprint allows pole mounting at building perimeters without creating obstacles or requiring additional infrastructure. In coastal installations, the corrosion-resistant construction prevents the salt-spray oxidation that degrades unprotected terminal blocks and power connectors within months.
Typical Applications
Security integrators specify the WP3 for outdoor surveillance camera head-ends, remote intercom power distribution, perimeter access control readers, lighting automation nodes, and gate automation power supplies. Frequently deployed in pairs or groups at large properties to create distributed power nodes that reduce voltage drop and improve system reliability. The sealed construction also makes it suitable for industrial sites, parking structures, and salt-marsh or coastal environments where standard plastic enclosures degrade rapidly.
Frequently Asked Questions
Q: Can the WP3 be mounted indoors?
A: Yes. While engineered for outdoor use, the WP3's compact size and sealed design make it suitable for indoor mechanical rooms, utility closets, or utility vaults where space is constrained and a single hardened power distribution node is preferred.
Q: Will the WP3 protect against full submersion?
A: No. NEMA 4/IP66 protects against rain, wind-driven spray, and high-pressure water jets, but not submersion. If the enclosure will be partially submerged or located below flood elevation, specify an IP67-rated variant instead.
Q: What power supplies and chargers fit inside the WP3?
A: Interior volume accommodates standard Altronix power supplies and battery backup chargers within the 5.6-inch depth. Confirm specific model dimensions with the manufacturer before ordering, as battery backup modules with large transformer cores may require external mounting.
Q: Does the WP3 include a built-in power supply or charger?
A: No. The WP3 is an enclosure only. You must specify and install a compatible Altronix power supply and, if needed, a battery backup charger module inside it.
Q: Is thermal management built in?
A: The enclosure is sealed for weather protection, not actively cooled. In hot climates or high-wattage installations, account for internal temperature rise and ensure the power supply and charger you select are rated for the anticipated internal temperature range.

During site planning for a multi-building security retrofit at a coastal property, we evaluated the Altronix WP3 as the housing solution for outdoor power distribution. The NEMA 4/IP66 rating was essential—our previous installations in coastal zones had suffered corrosion failures on exposed power terminals within 18 months. The WP3's sealed construction and corrosion-resistant materials eliminated that failure mode entirely. The compact 13.3-inch height allowed us to meet aesthetic requirements while maintaining proper environmental protection and adequate interior volume for an Altronix power supply and battery backup charger.
Technical Highlights:
- NEMA 4/IP66 Sealing: Dust and water ingress are completely prevented, eliminating condensation and corrosion failures that plague unprotected outdoor power nodes in salt-spray, humid, or rainy climates.
- Compact Footprint (13.3in × 11.3in × 5.6in): Fits pole-mount and wall-mount applications without requiring custom fabrication or extensive site modification; internal volume is sufficient for a power supply, charger, and terminal blocks without daisy-chaining separate enclosures.
- Corrosion-Resistant Materials: Designed for extended outdoor exposure without annual maintenance or replacement cycles—a real cost driver in coastal and industrial installations where untreated enclosures degrade rapidly.
Deployment Considerations:
- The WP3 is an enclosure only—you must supply and install a compatible Altronix power supply and battery backup charger inside it. Do not assume it includes power components.
- Interior depth (5.6 inches) limits component choice; confirm power supply and charger dimensions before ordering. Large battery backup modules with transformer cores may require external mounting or a larger enclosure variant.
- Sealed design protects against weather but offers no active cooling; in hot climates or high-wattage installations, interior temperature rise is possible. Verify thermal ratings of components you plan to house inside.
The WP3 is the right choice for coastal or harsh-climate outdoor power distributions where corrosion resistance and sealed protection are non-negotiable. In inland or protected sites, a standard outdoor power box may suffice; in extreme salt-spray or industrial chemical environments, confirm with the manufacturer that corrosion-resistant coating extends to fasteners and hinges.
