DC Power Supplies
DC power supplies (also known as AC-DC power supplies, programmable DC power supplies, or benchtop power supplies) are precision instruments that provide stable voltage or current. They are broadly classified into linear regulator and switching regulator types based on their control topology. For details, please refer to "What is the DC power supply? (Basic Knowledge)".
Matsusada Precision offers high-performance DC power supplies and bidirectional (regenerative) power supplies engineered for high reliability, low-noise performance, and high power density.
Our comprehensive lineup ranges from ultra-compact precision benchtop models to high-power rackmount and cabinet systems. From this page, you can access our full range of products and search for the DC power supply that best suits your application. If our standard products do not meet your specifications, we offer custom solutions to accelerate your development process.
Our lineup includes the ultra-compact R4K-36 series, featuring our proprietary high-efficiency switching technology. We also offer the R4G series (linear type) for ultra-low ripple performance and the PRTM series for high-power applications up to 120 kW. For automotive testing, the PBR series bidirectional power supplies are ideal for evaluating PCUs, ECUs, and inverters. We provide a wide variety of programmable solutions, including high-precision reference voltage generators.
Our programmable DC power supplies serve research institutes and industrial facilities worldwide. Common applications include 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.
