UL Certified Waterproof Power Supply Series - North American Market Compliance & Safety

Example Power's waterproof power supply series has officially received UL certification, marking a significant milestone in our commitment to global safety standards. This certification validates that our products meet the rigorous safety requirements set by Underwriters Laboratories, one of the most recognized safety testing organizations worldwide.

The following table summarizes the key certification parameters and their applicable standards for our waterproof power supply series:

UL certification is essentially a passport for electronic products entering the North American market. In the United States and Canada, most electrical products sold commercially must carry a Nationally Recognized Testing Laboratory (NRTL) mark, with UL being the most widely accepted. Without this certification, manufacturers face significant barriers including customs rejection, retailer refusal, and liability exposure.

For our customers in North America, this means they can now specify Example Power waterproof supplies in their projects with full confidence in regulatory compliance. Distributors, system integrators, and end users in the US and Canadian markets can procure our products knowing they have been independently tested and verified against stringent safety benchmarks.

The UL certification process for our waterproof power supply series involved comprehensive testing across multiple safety dimensions. Below are the critical test categories and their significance:

Each unit was subjected to 3000V AC for one minute between primary and secondary circuits without breakdown or flashover. This test ensures that even under fault conditions, the power supply maintains adequate electrical isolation to protect end users from electric shock hazards.

Measured at 500V DC, all models demonstrated insulation resistance exceeding 100 MΩ, far surpassing the minimum requirement. This parameter is particularly critical for waterproof units where moisture ingress could compromise insulation integrity over time.

Under full load operation at 40°C ambient temperature, all models remained within Class B insulation temperature limits. The waterproof enclosure design was validated to provide adequate heat dissipation while maintaining IP67 sealing integrity, ensuring long-term reliability in demanding outdoor and industrial environments.

We are proud to announce that the UL certification covers our entire waterproof power supply series, spanning from 5W to 200W output power ratings. This comprehensive coverage means customers can standardize on Example Power across their complete product range without mixing certified and uncertified units.

The certified series includes single-output models at 5V, 12V, 24V, and 36V, as well as dual-output configurations for applications requiring multiple voltage rails. All models maintain the IP67 waterproof rating, making them suitable for outdoor signage, marine applications, industrial automation, and architectural lighting installations where exposure to moisture and dust is a constant concern.

With this UL certification achievement, Example Power reinforces its position as a reliable partner for power solutions that demand both environmental protection and regulatory compliance. We continue to invest in safety certification across our product portfolio to serve the evolving needs of the global market.
