01
Interference first
Every design starts with the noise it must suppress and the standards it must meet.
About us
Power line filters engineered for cleaner, safer power.
WELLEMC Electronics Ltd. is a professional power line filter manufacturer based in Jiangmen, Guangdong, China.
We design and build single-phase, three-phase, and three-phase + neutral EMI filters that suppress interference at the source, helping equipment pass EMC testing and run reliably in the field.
Our story
Focused on one product, done properly: power line filters.
WELLEMC started with a single focus — electromagnetic interference at the power entry — and has kept that focus ever since.
From our base in Jiangmen, Guangdong, we combine in-house design, production, and testing to serve equipment makers in China and abroad with both standard filter series and custom-engineered solutions.
By the numbers
A focused filter specialist, not a general catalog.
We measure success by interference suppressed, certifications passed, and equipment makers who come back for their next project.

How we work
The standards behind every filter we ship.
Four principles guide how we design, test, and deliver every power line filter.
02
Built to certify
Filters are engineered to help equipment pass EN/IEC EMC testing with margin, not luck.
03
Honest specifications
Rated current, voltage, leakage current, and insertion loss published clearly for every model.
04
Easy to integrate
Standard footprints and clear drawings make our filters drop-in choices for new and existing designs.
