Waterproof AC/DC Power Adapter Full Custom Development Case Studies | From Enclosure and Circuit Design

What Is "Full Custom" for Waterproof AC/DC Power Adapter?

Full custom waterproof AC/DC Power Adapter refers to designing from scratch, including circuit design, enclosure structure, and waterproof specifications.

We develop dedicated power supplies for specific applications that cannot be supported by standard or semi-custom products.

Typical Requirements That Necessitate Full Customization

Full custom solutions are considered when the following conditions apply:

Design changes to the waterproof structure itself are required
Specific installation methods (embedded, permanent outdoor installation, submerged environments)
Special environmental resistance requirements (chemicals, salt damage, high temperature and humidity)
Size and shape constraints that cannot be met by existing Products
Compliance with in-house standards or customer-specified testing

Development Process (Overview)

Full custom development proceeds as follows:

Hearing regarding usage environment and required specifications
Concept design of circuit and enclosure
Prototyping and evaluation (including waterproof testing)
Mass production design and production launch

Development is carried out from the early design stage with consideration for stable mass production.

Differences from Semi-Custom

Item	Semi-Custom	Full Custom
Design Base	Existing Design	From Scratch
Waterproof Structure	Existing Specifications	New Design
Development Period	Short	Medium to Long Term
Initial Cost	Low	High
Degree of Flexibility	Limited	High

"Start with Semi-Custom Consideration" Is Also Possible

Depending on the required specifications, full customization may not be necessary, and many cases can be handled with semi-custom solutions. We provide consultation from the specification review stage to avoid overengineering.

It is perfectly fine to start with confirming the feasibility of semi-custom support. Click here for details on semi-custom support ▶
