Bosch NDA-U-PA0 Surveillance Cabinet 24VAC

Bosch NDA-U-PA0 Outdoor Surveillance Power Cabinet

Overview

The Bosch NDA-U-PA0 is an aluminum alloy surveillance cabinet designed for harsh outdoor environments where cameras and ancillary equipment need conditioned, protected power at the pole or wall. Accepting 24 VAC input at 50/60 Hz, it delivers a regulated 96 VA output with dedicated fused circuits — 2.0 A for the camera and 3.15 A for the internal heater — so camera power and environmental conditioning are independently protected. The NDA-U-PA0 (often searched as NDA U PA0) addresses a common field problem: getting stable, code-compliant power to a camera in an exposed location without running a bulky secondary enclosure or improvising weatherproofing.

Built from aluminum alloy and finished in white RAL 9003, the cabinet measures 170.0 mm × 216.4 mm × 105.0 mm and weighs 2,337 g — compact enough to mount close to the camera head, heavy enough to stay put. The white finish is not cosmetic: in direct sun exposure, light-colored enclosures run significantly cooler internally, extending component life in summer peak conditions.

Key Features

• IP66 Ingress Protection: Dust-tight and protected against powerful water jets from any direction. Rain, car-wash runoff, pressure cleaning near the mount — none of it gets in. If your site includes periodic power washing or sits in a coastal spray zone, IP66 is the floor you need, not a nice-to-have.
• IK10 Impact Rating: The highest standardized mechanical impact rating — withstands 20 joules, equivalent to a 5 kg mass dropped from 400 mm. In parking structures, loading docks, or any site with vehicle proximity or foot traffic, IK10 means the cabinet survives incidental contact without breaching the enclosure seal.
• –60°C to 55°C Operating Range: This is an unusually wide thermal envelope. The lower bound of –60°C covers arctic and subarctic deployments — Siberian substations, northern Canadian infrastructure, high-altitude mountain installations — where most commercial enclosures fail long before dawn. The 55°C ceiling handles desert summers and rooftop installs in full sun.
• 0% to 100% Condensing Humidity Tolerance: Rated for fully condensing environments — meaning the cabinet can handle the thermal cycling from –60°C nights to warm days that causes moisture to form inside enclosures. The sealed IP66 body prevents ingress; the rated humidity tolerance confirms the internal components are specced to survive it.
• NEMA TS2 Vibration and Shock Ratings: Meets NEMA TS2 — the transportation infrastructure standard used for traffic controllers and roadside equipment. If the cabinet mounts on a pole subject to traffic vibration, wind buffeting, or nearby construction equipment, NEMA TS2 ensures the internal connections and fuse contacts don't work loose over time.
• Dedicated Fused Output Circuits: The 2.0 A camera circuit and 3.15 A heater circuit are independently fused. If the heater element faults, the camera stays powered — and vice versa. This separation matters on a remote pole camera where a service call costs real money. Fuse protection on the input side at 5.0 A limits upstream wiring exposure.
• Peak Current Handling — 21.4 A at 1500 W: The cabinet is specced for transient peak draw well above its 96 VA continuous rating. Cold-start inrush from the heater element and camera simultaneously won't trip the input fuse or cause a voltage dropout that resets the camera.
• CE, UL, and EAC Compliance: Three distinct regulatory marks covering European, North American, and Eurasian Customs Union markets. For projects with multi-region procurement or export requirements, a single SKU clears compliance in all three zones — no substitute part, no separate compliance documentation per region.

Integration and Compatibility

The NDA-U-PA0 accepts 24 VAC input — the distribution voltage used in large multi-camera runs where the voltage drop over long cable runs makes higher-voltage AC distribution preferable to low-voltage DC. Cameras in the Bosch surveillance line that operate on 24 VAC pair directly with this cabinet. The output fusing is sized for a single camera with integrated heater rather than a multi-camera distribution point, making this a per-camera enclosure, not a branch distribution panel.

The aluminum alloy construction is electrically conductive, so proper grounding of the enclosure to the site ground system is required by most electrical codes when metal enclosures house powered equipment. The 170.0 mm × 216.4 mm × 105.0 mm footprint allows mounting on standard pole brackets or wall plates used across the Bosch security product line.

For broader deployment planning, review the outdoor IP camera category to match camera models with compatible housings, and consult a PoE and power planning guide if your infrastructure mixes PoE and 24 VAC camera runs. Integrators specifying network video recorders for multi-site deployments should account for the cabinet's 96 VA per-camera power budget when sizing upstream transformer capacity.

Frequently Asked Questions

Q: What input voltage does the NDA-U-PA0 require?

A: The NDA-U-PA0 accepts 24 VAC input at 50 or 60 Hz. It is not compatible with DC input or with standard 120/240 VAC line voltage directly — a step-down transformer supplying 24 VAC is required upstream.

Q: What is the continuous output rating of the NDA-U-PA0?

A: The output is rated at 24 V, 96 VA continuous. Peak handling is rated at 21.4 A / 1,500 W to accommodate inrush currents from cold starts.

Q: Is the NDA-U-PA0 suitable for extreme cold environments?

A: Yes. The operating temperature range is –60°C to 55°C, covering arctic, subarctic, and high-altitude installations where most commercial enclosures are not rated to operate.

Q: What regulatory certifications does the NDA-U-PA0 carry?

A: The NDA-U-PA0 carries CE (European), UL (North American), and EAC (Eurasian Customs Union) certifications, making it suitable for multi-region infrastructure projects without requiring a region-specific alternative SKU.

Q: Are the camera and heater outputs independently protected?

A: Yes. The camera output is fused at 2.0 A and the heater output is fused at 3.15 A separately. A fault on one circuit does not interrupt the other, which is critical for maintaining camera uptime during a heater fault in a remote location.

Q: What impact and vibration ratings does the NDA-U-PA0 carry?

A: The enclosure is rated IK10 (highest standardized impact class — 20 joules) and meets NEMA TS2 for both vibration and shock, making it appropriate for pole-mounted or roadside installations subject to mechanical stress.

Ted Perry

The NDA-U-PA0 is one of the few surveillance power cabinets I'd specify without hesitation for a northern Canada or Alaska pole camera installation. That –60°C lower bound is not marketing copy — it matches the cold-start specs you need when cameras are going up on highway interchanges or utility perimeters in climates where January nights hit –50°C and the heater element is the only thing keeping the lens clear. The independently fused outputs are the right engineering call for remote sites.

Technical Highlights:

• –60°C to 55°C Operating Temperature: A 115°C total thermal span that covers the full range from arctic infrastructure to sun-exposed rooftop installs in the Middle East or Southwest US — without swapping enclosures.
• IK10 + IP66 Combined Rating: IP66 keeps water out; IK10 means the seal survives a mechanical hit. Most pole-mount enclosures carry one or the other. Carrying both on a 2,337 g aluminum cabinet means the physical integrity of the installation doesn't depend on careful placement away from traffic.
• Independent 2.0 A / 3.15 A Fused Outputs: Sized correctly — the heater fuse is heavier than the camera fuse because heater inrush is the bigger transient. A single shared fuse sized for the heater would be oversized protection for the camera circuit. This split is the right design for a remote, hard-to-service location.

Deployment Considerations:

• The 24 VAC input means you need a step-down transformer in the power chain — budget for that upstream device and its enclosure. In long cable runs, 24 VAC distribution reduces voltage drop compared to 12 VDC, but you're still bound by the 96 VA continuous output ceiling per cabinet, one camera per enclosure.
• The aluminum alloy body requires a ground bond to the site grounding system per NEC and most local electrical codes. Don't skip the ground lug — at IK10 impact sites, the enclosure is likely in a zone where a fault-to-enclosure scenario is a real risk.

For highway interchange or remote utility perimeter cameras in sub-arctic or desert climates, the NDA-U-PA0 is the right enclosure: the thermal and impact specs are genuine, the regulatory marks cover North American and European procurement, and the independent fusing keeps the camera alive through a heater fault on a pole you won't service for weeks.
