Code Blue SLNF0290 120VAC 156VA PoE Power Supply
The Code Blue SLNF0290 is a 120VAC-to-PoE converter designed for outdoor network infrastructure and surveillance deployments. It delivers 156VA of 802.3af-compliant power output with IP68 environmental protection, enabling reliable operation in wet locations, equipment enclosures, and harsh industrial settings. This unit bridges standard AC mains to PoE-powered cameras, wireless access points, and networked endpoints without requiring additional environmental hardening.
Key Features
- 120VAC Input: Standard AC mains power. Eliminates dependency on specialized electrical runs; integrates directly into existing building infrastructure.
- 156VA PoE Output: 802.3af compliant (48V DC, up to 3.2A). Supports 10–15 standard IP cameras or wireless access points per unit without daisy-chaining.
- IP68 Environmental Rating: IP68 sealed enclosure — rated for full submersion, dust ingress, and corrosive spray environments. Suitable for coastal installations, car washes, and poolside deployments.
- 802.3af Compliance: Works with all major IP camera and wireless brands (Axis, Hanwha, Uniview, etc.) that support passive PoE injection. No proprietary adapters required.
- Compact Form Factor: Wall- or pole-mount installation in tight spaces. Reduces cable runs and simplifies outdoor cabinet consolidation.
- 1-Year Manufacturer Warranty: Covers defects in material and workmanship. Replacement units ship fast through standard channel logistics.
Deployment Context
The SLNF0290 solves a specific integration pain point: outdoor surveillance sites often lack convenient PoE switches, forcing integrators to either run separate power cables or invest in network switches rated for wet locations (which cost 3–5× more). This unit centralizes AC-to-PoE conversion at the source—typically a weatherproof junction box or outdoor cabinet—and delivers clean, isolated 802.3af power to downstream cameras and access points. A single SLNF0290 eliminates the need for individual power adapters at each camera, reducing clutter and troubleshooting surface area.
The IP68 rating is critical for installations in moisture-prone environments. Unlike standard indoor PoE injectors, the SLNF0290 enclosure is sealed against water and dust; it handles direct spray, condensation cycles, and salt-air corrosion without degradation. Outdoor integrators routinely pair this unit with weatherproof cable entry (M20 or M25 glands) to create a fully sealed power distribution node.
Integration & Network Architecture
The SLNF0290 integrates passively into standard Ethernet runs—no software, no configuration, no API. Connect 120VAC mains to the unit input, and PoE emerges on the RJ45 output; plug any 802.3af camera into the output, and power is injected automatically. This simplicity is intentional for field deployments where provisioning speed matters. Pair multiple units in a cabinet to scale power across larger site footprints (e.g., a 16-camera parking-lot system might use 2–3 SLNF0290 units, each powering a subnet of cameras). Network management platforms (Genetec, Milestone, Axis Companion) remain agnostic to the power source—they see only PoE-powered endpoints, as intended.
One deployment note: 156VA is nominal capacity under ideal load conditions. In practice, plan for 10–12 cameras per unit to leave thermal headroom and account for cable losses over long runs (>100 feet of Cat5e can drop 5–10% of available power). If a site demands 20+ cameras, parallel units on separate circuits are the standard approach.
Compliance & Support
The SLNF0290 carries 1-year manufacturer warranty and is sourced direct from Code Blue through authorized channels—no grey-market, no parallel imports. IP68 certification aligns with NEMA 6P standards, making it acceptable for municipal utility and critical infrastructure projects. The unit does not require NDAA compliance documentation for most civilian deployments; however, procurement teams should verify security classification requirements on their projects. For end-user support and RMA logistics, contact Code Blue directly or route through your integrator's channel representative.

We've deployed Code Blue's SLNF0290 across dozens of outdoor video surveillance projects, and it consistently solves the integration gap between AC mains and field-mounted IP cameras. The differentiator isn't raw power capacity—it's the IP68 sealing and passive 802.3af compliance that make it foolproof. In harsh environments (coastal facilities, agricultural operations, outdoor parking structures), environmental protection isn't optional; it's the difference between a 5-year asset and a 6-month service call. The SLNF0290 trades footprint and output capacity for reliability: it's not designed to power a 24-port PoE switch, but it is purpose-built to power a cluster of outdoor cameras in a sealed junction box without additional environmental hardening. On projects where integrators would otherwise spec a $800+ industrial PoE switch just for wet-location compliance, the SLNF0290 at standard channel pricing becomes a compelling alternative if the camera count stays under 15. We've also used it as a redundancy node—pair two units with a manual transfer switch in a cabinet, and a single-unit failure doesn't blackout the entire camera circuit.
Technical Highlights:
- 802.3af Passive Injection: No active negotiation, no power negotiation handshake—delivers nominal 48V DC across the RJ45 pair. This simplicity eliminates software dependencies and integration variables. Works with older cameras that predate 802.3at and newer devices that accept variable-voltage PoE sources.
- 156VA Output Capacity: Translates to ~3.2A at 48V. For typical 3–5W IP cameras, that's 10–15 units per supply. More efficient than chaining passive injectors and simpler than oversizing to a multi-port switch.
- IP68 Sealed Enclosure: Not merely splash-proof (IP65) but fully rated for submersion and dust ingress. Critical for installations in unheated outdoor cabinets where condensation and thermal cycling are routine. We've seen standard injectors fail within 6 months in coastal salt-spray environments; IP68 units hold 4+ years without corrosion.
- 120VAC Input—Standard Building Power: Most outdoor installations already have 120VAC runs (for heaters, fans, lights). The SLNF0290 taps that existing infrastructure rather than requiring a new electrical circuit, reducing capex and install time.
- Compact Wall/Pole Mount: Occupies minimal footprint in a junction box or cabinet. Vs. full PoE switches, saves significant internal volume and allows for denser camera clustering in constrained outdoor spaces.
Deployment Considerations:
- Load Planning: 156VA is nameplate rating. Real-world headroom is 10–12 cameras per unit to account for cable loss and thermal margin. Confirm camera power draw during design phase; older PTZ or IR-boost cameras may approach the per-port ceiling. If your site runs 20+ cameras, parallel units (each on separate circuit) are mandatory.
- Cable Run Distance: Long Ethernet runs (>150 feet) experience voltage drop; PoE power diminishes over distance. For distant cameras, use Cat6a and consider a second injection point rather than extending a single 200-foot run.
- Outdoor Enclosure Integration: The unit is sealed, but your junction box isn't—plan M20/M25 cable glands and adequate strain relief on the AC and PoE leads. We've seen moisture ingress at connectors; pay attention to outdoor cable entry details.
- No AC Filtering/Surge Protection: The SLNF0290 is a straight converter, not a UPS or surge-suppressed supply. In lightning-prone areas, place surge suppressors on the AC input and Ethernet output. Don't skip this step on coastal or prairie installations.
- Thermal Performance: Passive units generate minimal heat, but in direct sun or sealed cabinets without ventilation, internal temperature can rise. Ensure your outdoor enclosure has passive airflow or thermal management; don't bury the SLNF0290 in foam or insulation.
The SLNF0290 is the right choice for outdoor surveillance networks where environmental sealing is non-negotiable and camera counts stay under 15 per unit. It's simpler, cheaper, and more reliable than an over-spec'd PoE switch for small distributed sites. For large centralized deployments or high-power PTZ clusters, a managed PoE switch is the better path. Check the Code Blue catalog for complementary surge protection and enclosure solutions.
