Waterproof × Wide Temperature Support – Custom Solution for the "Invisible Power Supply" Case Study: FA Equipment Manufacturer

Achieved an AC adapter that simultaneously satisfies IP waterproofing, operation from -20 to +60℃, and high output through semi-customization utilizing existing assets. Introducing a case study of an FA equipment manufacturer who succeeded in mass production with zero design changes to the equipment.

"IP waterproof specification, −20 to +60°C, and yet no high-power output AC adapter..."Do you have such concerns?

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 a major modification of the equipment was the only option.

Challenges Before Implementation

Standard products do not simultaneously meet both IP waterproof and wide temperature (−20 to +60°C) requirements
Due to insufficient output, device design has to be changed
Risk of not meeting the new product release schedule

Our Solution

Step	Measure	Effect
1	Base reused adapter from existing 24V lineup	Minimized initial cost and lead time
2	Designed waterproof case using new mold	Ensured IP rating while maintaining optimal size
3	Replaced some parts with wide temperature compatible components	Maintained rated output even at −20 to +60°C

[Key Point] Instead of “full customization”, we made the most use of existing assets to balance cost and development speed!!

Results After Implementation

Started mass production on schedule with zero changes to the equipment design
Met short delivery times for additional specifications using stock parts and new case
One-stop solution to the issue of "limited options"

"Development, which had been delayed due to the power supply, suddenly progressed!"
