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, 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 handy-sized precision DC power supplies to tabletop 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 which best suits your application. Should you need specifications That are not covered by our standard products, we are able to respond quickly and efficiently to your requirements, thereby reducing your development cycles.

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

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.
