DC5V Meanwell Waterproof Power Supply

4 products

When your 5V LED lighting project needs to operate outdoors or in an environment where moisture, dust, condensation, or water exposure is a concern, a standard indoor switching power supply is not the right choice. SuperLightingLED's Mean Well 5V Waterproof Power Supply Series is designed to provide a more suitable power solution for outdoor and wet-location 5V LED installations.

These power supplies use a sealed IP67-rated enclosure, providing protection against dust and temporary water immersion when properly installed. This makes them a practical choice for applications such as outdoor LED strips, addressable pixel lighting, landscape accents, patios, decks, architectural lighting, signage, and other protected outdoor installations.

Our Mean Well 5V waterproof range covers 15W to 100W / 3A to 20A, providing practical options for both compact outdoor lighting and higher-current 5V addressable LED projects. If your project requires reliable 5V power in an outdoor or moisture-prone environment, and you prefer a professional Mean Well solution rather than a basic waterproof adapter, this series is designed for that exact requirement.

Why Choose a Waterproof 5V Power Supply?

5V LED systems are commonly used for addressable LED strips, pixel lighting, programmable LED projects, and other digitally controlled lighting, but they can require relatively high current. When these systems are installed outdoors, the power supply must handle both the electrical demand and the environmental conditions.

A standard open-frame or enclosed indoor switching power supply may provide the required 5V output, but it is not designed to be exposed to moisture or outdoor conditions. A waterproof power supply adds an important layer of protection by enclosing the AC-to-DC conversion electronics in an IP67-rated housing.

This makes the Mean Well waterproof series particularly useful when the power supply itself must be installed closer to the outdoor LED system, rather than being placed inside a separate dry electrical enclosure.

Meanwell Outdoor Waterproof 5V Power Supplies are IP67 rated, which means that the LED power supply has a high level of dust resistance (6) and is able to continue to operate normally after brief immersion in water (7).

The durable enclosure and special protective design are resistant to harsh weather conditions, UV rays, and other external environmental factors. This prevents moisture and dust from entering the interior of the LED light power supply, ensuring long-term reliability in outdoor environments.

IP67 Protection Does Not Mean “Install Anywhere”

An IP67 rating makes these power supplies suitable for many outdoor and wet-location applications, but it does not mean that every part of the installation can be left exposed without additional protection.

The AC input connections, DC output connections, connectors, cable joints, and LED strips themselves must also be properly protected and rated for the environment. Cable entries and connection points should be installed according to the manufacturer's requirements so that water cannot enter through the wiring.

For outdoor LED projects, think of the system as a whole:

Waterproof Power Supply + Waterproof Wiring/Connections + Weather-Appropriate LED Strip = Reliable Outdoor LED System

This is especially important for installations exposed to rain, sprinklers, condensation, or standing water.

Frequently Asked Questions About DC5V Meanwell Waterproof Power Supplies

Got questions before you spec your outdoor 5V lighting? I've been answering these on the support desk for 12 years. Here are the common ones.

These units are designed for permanent, hardwired installations, not plugging into a wall outlet. You'll see an AC input side (usually black, white, and green wires) and a DC output side (red and black). The AC side gets wired into a junction box connected to your mains power. The DC side connects to your LED lights. If you need a simple plug-in style, you're probably looking for a DC5V power adapter.

Not directly. These Meanwell LPV series power supplies are constant voltage, non-dimmable units. To dim your 5V strips, you need to place a PWM dimmer controller between the power supply's output and the LED strip itself. The power supply provides steady 5V, and the separate dimmer handles the brightness control.

This Meanwell 5V power supply is convection cooled, so it has no fan but does need airflow. The case itself acts as a heat sink. It can feel quite warm under full load, which is normal, but it shouldn't be too hot to touch. Don't bury it in insulation or pack it into a tiny, unventilated box. Giving it some open air space ensures it runs safely and lasts for its full expected lifespan.

These Meanwell units have built-in overload protection. If you draw too much current, the power supply won't explode; it will either shut down completely (hiccup mode, where it tries to restart every few seconds) or limit the current. Your lights will flicker, dim, or just not turn on at all. It's a safety feature to prevent damage. The solution is to reduce the load or get a higher wattage power supply.

Reliability and safety. The Meanwell 5V waterproof power supply is fully potted, meaning the internal components are encased in resin. This protects them from vibration and moisture far better than just putting an indoor-style power supply in a 'weatherproof' box, which can still have condensation issues. Meanwell's protection circuits are also top-notch, and they carry proper UL listings, which is often a requirement for permitted work.

Yes, it has a universal AC input range, typically from 90V to 264V AC. It automatically adjusts to whatever mains voltage you connect it to, so you can use the same model for jobs in North America, Europe, or Asia without worrying about a voltage switch. Just make sure your AC plug is appropriate for the local outlets.
