DC Power Supplies

DC power supplies, also known as AC-DC power supplies, regulated power supplies, or Programmable DC power supply, Bench power supply, Lab power supply, variable DC power supply, is a power circuit that supplies a constant voltage or current. They are roughly classified into Linear regulator and switching regulator types according to the control method. For details, please refer to "What is the 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.

We have a wide range of products, from palm-sized precision DC power supplies to benchtop sizes and high-power Rackmount/Cabinet types. From this page, you can access our full range of products and search to find the DC power supply that best suits your application. If our standard products don't meet your specifications, we offer custom solutions to reduce your development time.

For example, our DC power supplies include ultra-compact DC power supplies(R4K-36 series) that can fit in the palm of your hand and feature our original high-efficiency switching method and have multiple functions; ultra-low ripple DC regulated power supplies (R4G series) with linear regulator system, high power DC regulated power supplies with a power of 120 kW (PRTM series), power supplies for communication equipment, and bi-directional power supplies (regenerative power supplies) (PBR series) that are ideal for evaluating PCUs, ECUs, inverters, etc. We offer a wide variety of DC programmable power supplies, including bi-directional power supplies (regenerative power supplies) and high-precision reference voltage generators (PSX series, Japanese site).

Our programmable DC power supplies can be used in research institutes and factories around the world in fields such as energy/environment, vehicles/aerospace, Semiconductors (Process control, Burn-in), bio/medical, analytical instruments, electronics, and industry. Matsusada Precision's high-quality and reliable DC power supplies can easily satisfy the requirements of your OEM or laboratory applications.

Matsusada Precision classifies power supplies that generate voltages in excess of 1000 V (1 kV) as high-voltage power supplies. If you need a higher voltage, please refer to the page on high voltage power supplies.
