Overvoltage (surge) protection components for electronic devices

ALDERS offers your various different overvoltage (surge) protection components from the US-American manufacturer World Products Inc.. With these components you protect your electronic devices reliably from high overvoltages (surges).

We supply gas discharge tubes, thyristors, TVS diodes and varistors by WPI. The manufacturer’s overvoltage protection components all confirm RoHs. RoHs (“Reduction of Certain Hazardous Substances”) is an EU directive to limit hazardous substances. That means that during the production process at WPI no or only a limited amount of hazardous substances are used that are below the thresholds that are harmful to health and the environmentally.

Since 1970, the World Products Inc. offers environmentally-friendly and well-engineered and sophisticated solutions in the highest quality for electronic devices. With its range of products, the company focuses, above all on the main markets automotive, telecommunications, industry, energy supply and voltage protection.

You can rely on the many years of experience of the manufacturer when it comes to overvoltage protection components. At ALDERS we are convinced of the high quality and reliability of components by World Products Inc.
