Applications

Matsusada Precision's high-voltage power supplies

High-voltage power supplies are essential in many industries and sectors, including electronics, semiconductor, science, analytical, medical, healthcare, aerospace, environmental, industrial, manufacturing and research facilities. High-voltage applications are devices that utilize strong electric fields, generated by high voltage, to control or accelerate electrons and ions. Familiar examples of high-voltage power supplies include hospital X-ray machines, semiconductors used in smartphones and electronic devices, and display manufacturing equipment.

We at Matsusada Precision believe that understanding the different types of high-voltage power supplies available is key to selecting the right one for any given application. The term "high-voltage power supply" refers to a DC power supply that outputs high voltage.

At Matsusada Precision, we classify programmable power supplies with meters that can output voltages of 1000 V or more and embedded power supply modules that can output voltages of several hundred volts or more as high-voltage power supplies.

Whether they are classified as high voltage or simply DC depends on each company's product line and voltage.
