Ultra Low Noise Switching Power Supply

Daitron offers 300W type of Ultra Low Noise Power Supply model. You can choose 12V, 15V, 24V, 30V and 48Voutput voltage option.

All these voltage output model have ultra low ripple noise < 10mVp-p >.
This model is ideal solution for engineers who need very noise for your sensitive applications.
This feature can bring engineers small, light weight and high efficiency with ultra low noise feature.
You may replace linear power supplies into our ultra low noise switching power supply products.
Low conduction noise and low EMI feature can also save your resources for EMI design.
