DC Power Supplies

DC power supply, also known as an AC to DC power supply, Regulated power supply, or Programmable DC power supply, Bench power supply, variable dc power supply, is a power circuit that supplies a constant voltage or current. They are roughly classified into series regulator type and switching type according to the control method. For details, please refer to "What is DC power supply? (Basic Knowledge)".

Matsusada Precision's DC power supplies are high-performance DC regulated power supplies (DC power supplies)/bidirectional power supplies (regenerative power supplies) that pursue "compactness," "low noise," and "high power.
