AC adapters

Sanken offers a variety of high-efficiency, low noise, compact, and lightweight AC adapters, ideally suited for mobile electronic devices such as laptop PCs. High efficiency and low noise have been realized for all operation areas through the use of a low power consumption IC and low-noise transformer. Our AC adapters comply with all energy-saving regulations, the safety standards of each country, the EMI (noise) regulation, and the RoHS directive, and so can be used in the vast majority of countries.
