Waterproof x Wide-Temperature Support: Solving the "Hard-to-Find Power Supply" with Customization - Case Study of an FA Equipment Manufacturer

Achieve an AC/DC Power Adapter that simultaneously meets IP waterproofing, -20 to +60°C operation, and high output through semi-customization leveraging existing assets. Introducing a case study of an FA equipment manufacturer that succeeded in mass production with zero changes to equipment design.

"An AC/DC Power Adapter with IP waterproof rating, -20 to +60°C, and high output... doesn't exist..." Are you facing this challenge?

Many FA equipment manufacturers face the challenge of "harsh environments × high power."

This time, we introduce a case where our "semi-custom power supply" solved a situation in which existing lineup specifications did not match and major equipment redesign seemed unavoidable.

Challenges Before Implementation

Standard products do not satisfy both **IP waterproofing** and **wide temperature range (-20 to +60°C)** at the same time
**Equipment design changes** were unavoidable due to insufficient output
Risk of missing the new Products release schedule

Our Solution

Step	Action	Effect
1	Leveraged our existing 24V adapter lineup as a base	Minimized initial costs and lead time
2	Designed a new waterproof case with a new mold	Achieved IP rating while maintaining optimal size
3	Partially replaced components to support wide temperature range	Maintained rated output even at -20 to +60°C

[Key Point] Instead of "full custom," we **maximized the use of existing assets**, achieving both cost efficiency and development speed!!

Results After Implementation

Mass production started on schedule with zero changes to equipment design
Additional specifications supported with short lead times using stocked parts + new case
Solved the issue of "limited options" with a one-stop solution

"Development that had been delayed due to power supply issues moved forward all at once!"
