Question 1

What is the minimum order quantity (MOQ) for a custom power adapter?

Accepted Answer

Standard housings start from 500 pcs per model, because that is the quantity at which our SMT line can be tooled economically without amortising set-up cost into the unit price. Fully bespoke enclosures require a new injection mould, so we normally recommend 3,000 pcs or more for the first order to keep the tooling share reasonable.

Question 2

How long does sampling and mass production take?

Accepted Answer

Electrical samples built on an existing platform are ready in 7–10 working days. A new PCB layout with safety-compliant transformer design takes 15–20 days. Mass production lead time is typically 20–30 days after sample approval, subject to plug type, cable set and certification status.

Question 3

Which safety and efficiency certifications can you supply?

Accepted Answer

We hold more than 120 valid certificates covering UL/cUL, CE (EN 62368-1), UKCA, CCC, PSE, KC, SAA/RCM, BIS and CB reports, together with DoE Level VI and EU ErP Tier 2 no-load/average-efficiency compliance. IEC 60601-1 designs are available for medical AC adapters with 2×MOPP isolation.

Question 4

Which protection circuits are built into FuYun adapters as standard?

Accepted Answer

Every switching design includes over-voltage protection (OVP), over-current protection (OCP), short-circuit protection (SCP), over-temperature protection (OTP) and no-load standby power control. Y-capacitor and common-mode choke filtering keeps conducted emissions within EN 55032 Class B limits.

Question 5

How do you guarantee batch-to-batch consistency?

Accepted Answer

Production follows ISO 9001 procedures and a documented SOP: bare-board test, first-article function test, ultrasonic welding, 100% hi-pot test, burn-in ageing and final function test. Test records are archived for years so every serialised unit remains 100% traceable to its component lot.
