What is a Power Supply? (Basic Knowledge)

The product information pages on this web site include many power supply units that were designed, developed, and manufactured by Matsusada Precision at our locations around Japan.

When considering output voltage, they can be classified as programmable DC power supplies that are rated up to several hundred volts, high-voltage power supplies (stationary type) and high-voltage power supplies (module type) that are rated up to several thousand or even tens of thousands of volts, and AC power supplies and bipolar power supplies/power amplifiers that can provide AC output.
For example, even for products that operate on batteries, like mobile phones, a variable DC power supply (a power supply whose output can be changed within a rated range) is used during the research and development stage to perform simulations under a variety of conditions.

On the other hand, AC power supplies and bipolar power supplies/power amplifiers are used for products that operate on AC rather than batteries (= DC).
In addition, a strong electric field is required to detect and control the behavior of electrons in equipment such as electron microscopes (microscopes that use a beam of electrons rather than visible light to observe a sample) used in scientific experiments, X-ray inspection systems/X-ray CT used for medical applications, and light receiving and emitting devices used in optical communications and space science experiments. High-voltage power supplies (stationary type) and high-voltage power supplies (module type) are useful for creating such electric fields.

In any case, particularly stable output (voltage and current) is required for research and development. A DC power supply that includes technology for stabilizing its output is called a stabilized DC power supply. Variable power supplies are sometimes called programmable power supplies.
