Solved power issues with imported devices! A case study of replacing non-PSE compliant adapters within three weeks

AC/DC power adapters — desktop & wall-mount included with imported equipment have not obtained PSE certification... With Unifive, existing 24V models can be semi-customized and completed from analysis to mass production in just 3 weeks. We also accommodate small lots and short delivery times.

"Have you experienced issues like: 'Even though we introduced equipment, devices, or LED lighting from overseas manufacturers, the AC/DC power adapters — desktop & wall-mount that came with them have not obtained PSE certification...', or 'We want to import and sell overseas products domestically, but they don't have a PSE mark...'?"

Inspection devices on production lines, hotel lighting, office AV equipment — while the settings differ, the challenges are the same.

This time, we introduce an example of how we quickly resolved a power supply issue for an LED lighting system faced by an equipment company, using semi-custom support based on our standard products.

Issue and Background

Imported LED lights from an overseas manufacturer scheduled to be delivered to a domestic hotel chain. The included adapters violated PSE (potential fire hazard). The importer refused to replace them, requiring an urgent switch to PSE-compliant products.

Our Solution

Step	Measure	Effect
1	We analyzed the actual LED lights to examine voltage and current in detail	Accurately understood the required specifications
2	Semi-customized existing 24V AC/DC power adapters — desktop & wall-mount	Minimized initial cost and lead time
3	Completed prototype → evaluation → mass production in about 3 weeks	Ensured replacement schedule
4	Submitted PSE test report and technical documents immediately	Accelerated internal approval

[Key Point] Not “full custom” but maximum use of existing assets to achieve both cost-efficiency and development speed!!

Results After Implementation

"After switching to Unifive products, the overheating issue disappeared, and we were completely freed from PSE concerns!"
