Altronix LPS3WP12220 12VDC 2.5A Weatherproof Power Supply — 220V Input
Overview
The Altronix LPS3WP12220 is a single-output, weatherproof power supply designed for surveillance and access control installations where a local 220V AC mains supply feeds a 12V DC device — and the power supply itself needs to survive outside the equipment room. Producing 2.5A at 12V DC from a 220V AC input, this unit fits deployments in international markets or in facilities wired to 220V standards, including many industrial sites, warehouses, and commercial buildings outside North America. If your camera, access reader, or alarm panel calls for 12VDC and your feed is 220VAC, the LPS3WP12220 closes that gap without requiring a separate step-down transformer or indoor-rated enclosure.
Altronix has built a long-standing reputation in the low-voltage security power market, and the Altronix power supply line spans everything from small single-output supplies to multi-output rack-mount assemblies. The LPS3WP12220 sits in the weatherproof segment of that catalog — a deliberate choice for integrators who need to locate the power source close to the device rather than running long cable runs from a protected interior panel.
Key Features
- 12V DC / 2.5A Output: At 30W of continuous capacity, this supply comfortably powers a full-featured IP camera with IR, a PTZ drive unit at standby, or an access control reader with electric strike — without running the unit near its thermal limit. Headroom matters in enclosed outdoor enclosures where heat builds.
- 220V AC Input: Designed for 220VAC mains rather than 120V — critical for international deployments, industrial sites, and any facility where the local distribution panel is wired to European or industrial 220V standards. Using a 120V-rated supply on a 220V feed will destroy it; the LPS3WP12220 is purpose-built for this voltage tier.
- Weatherproof Enclosure: The WP designation in the model name indicates a weatherproof housing — meaning the supply can be mounted in non-conditioned spaces, exterior equipment cabinets, or outdoor enclosures without requiring an additional protective shell. This eliminates the cost and complexity of a secondary NEMA enclosure in many field installations.
- Compact, Field-Deployable Form Factor: Locating a power supply close to its load — rather than centrally distributing 12V over long cable runs — reduces voltage drop and eliminates the wire gauge calculations that come with driving 12V loads over 50+ foot runs. The LPS3WP12220 enables a clean local-power architecture that is easier to troubleshoot and less vulnerable to a single point of failure.
- Single-Output Design: One output rail keeps the load isolated. If you're powering a camera or reader that draws intermittent surge current (IR illuminators cycling, lock solenoids actuating), a dedicated supply means those transients don't cross-contaminate other devices sharing a common rail.
- Altronix Ecosystem Compatibility: The LPS3WP12220 is compatible with the Altronix PMK1 Pole Mount Kit for outdoor enclosures, allowing the unit to be pole-mounted directly at a perimeter camera location — reducing cable run length to the camera and keeping the installation self-contained. This is the standard approach for standalone perimeter camera posts.
Integration and Compatibility
This supply is a fit for any 12VDC device that draws 2.5A or less and is located in an area served by 220VAC power. Common pairings include analog and IP cameras with onboard IR (typically 10–18W at full IR drive), access control readers, electric locks rated for 12VDC, and motion detectors requiring a regulated 12V feed. Verify your device's actual current draw under load — not just the rated maximum — before selecting this supply; a camera rated at 2.5A max may average 1.2–1.8A, but inrush on startup or IR activation can spike higher momentarily.
For installations requiring pole mounting, the Altronix PMK1 Pole Mount Kit is the matched accessory for this enclosure family. Review your local security power supply installation codes for outdoor equipment; some jurisdictions require conduit entry into the enclosure even on weatherproof-rated units. Confirm conduit knockout compatibility with the enclosure before finalizing your install design.
If your deployment calls for multiple 12V outputs from a single supply — for example, powering a camera, a reader, and a door strike from one location — consider a multi-output Altronix supply in the same family rather than paralleling outputs from this unit. The LPS3WP12220 is a single-output supply and is not designed for paralleled-load distribution without a proper output distribution block.
Integrators specifying access control hardware at international sites or in 208–240VAC-fed industrial panels should shortlist this unit early in the design phase. The 220V input compatibility is the defining selection criterion here — it is not a minor variant of a 120V supply but a separate specification with genuine field importance.

Frequently Asked Questions
Q: What is the output of the Altronix LPS3WP12220?
A: The LPS3WP12220 outputs 12V DC at 2.5A (30W continuous). It accepts 220V AC input and is not designed for 120V mains.
Q: Can the LPS3WP12220 be used with 120V AC power?
A: No. The LPS3WP12220 is rated for 220V AC input. Connecting it to a 120V supply may result in incorrect output voltage or damage to the unit. If your mains supply is 120V, select a 120V-input variant from the Altronix line.
Q: Is the LPS3WP12220 suitable for outdoor installation?
A: Yes. The WP designation indicates a weatherproof enclosure, making it suitable for non-conditioned spaces and outdoor equipment cabinets without requiring a separate protective housing. Always verify local code requirements for conduit entry on outdoor electrical equipment.
Q: What devices can the LPS3WP12220 power?
A: Any 12VDC device drawing 2.5A or less — including IP cameras, analog cameras with IR, access control readers, motion detectors, and 12VDC electric locks. Confirm your device's actual operating and inrush current before selecting this supply.
Q: Does the LPS3WP12220 support pole mounting?
A: Yes. The Altronix PMK1 Pole Mount Kit is a compatible accessory designed for outdoor enclosures in this product family, allowing the supply to be mounted directly on a camera or equipment pole.
Q: Can I run multiple devices from the LPS3WP12220 simultaneously?
A: The LPS3WP12220 is a single-output supply. You can power multiple devices from one output only if their combined current draw stays within the 2.5A rating and you use an appropriate output distribution block. For multi-device installations, a purpose-built multi-output Altronix supply is the cleaner solution.
The LPS3WP12220 is one of those unglamorous products that solves a very real field problem: you have 220V AC at the pole or cabinet, you need clean 12V DC at the device, and you need the supply to live outdoors without a secondary enclosure. The 2.5A output ceiling is adequate for a single camera or reader in normal operation, and the weatherproof housing saves a meaningful step in the installation — no separate NEMA box means less hardware, fewer sealing points, and a faster rough-in.
Technical Highlights:
- 220V AC Input: Purpose-built for 220VAC mains — not a dual-voltage unit and not compatible with 120V feeds. This is the core specification that drives the selection; verify mains voltage at the cabinet before ordering.
- 12V DC / 2.5A Output: 30W continuous is enough for most single-camera or single-reader scenarios, including cameras with active IR illumination. Inrush spikes from IR LED arrays and electric locks can momentarily exceed steady-state draw — don't spec this supply into a load that rides at 2.3–2.4A steady, as you'll have no thermal headroom.
- Weatherproof Enclosure: The WP housing allows direct outdoor mounting without a secondary protective enclosure — a genuine time and cost saver on pole-mount perimeter camera installations, particularly when paired with the Altronix PMK1 Pole Mount Kit.
Deployment Considerations:
- This supply is a strong fit for perimeter camera poles at sites with 220V infrastructure — international facilities, industrial campuses, and retrofit projects in European-standard-wired buildings. Mount it at the pole, run a short 12V tail to the camera, and you eliminate the voltage-drop math on a long 12V cable run from a distant panel.
- The single output rail is a limitation if you're trying to power more than one device from one enclosure location — plan for a multi-output supply or a distribution block if your pole mount carries both a camera and a reader.
The LPS3WP12220 belongs on the BOM for any perimeter camera installation at a 220VAC-fed site where the integrator wants to close-couple the power supply to the camera and avoid a long low-voltage home run back to the equipment room.
