Matsusada offers a wide range of reliable benchtop switching regulator DC power supplies, from power output ranging from 0.2 W to 1,200 W, output voltage ranging from 2V to 1 kV, and output current range of 0.1 to 180 A. This comprehensive range makes Matsusada's benchtop DC power supplies a highly scalable solution for the DC power needs of a wide range of industrial, commercial, and academic entities.

There are seven different series:

R4K-36 series: Ultra-compact 36 W power supplies featuring precise manual and remote output control with high resolution. The fanless design ensures quiet operation, making them ideal for desktop use.

R3K-36 series: A cost-effective model based on the R4K-36 series. It retains essential performance features while streamlining communication functions for simplified operation.

R4K-80 series: A compact 80 W programmable power supply series with an ultra-slim profile of just 35 mm width. Features include power factor correction and universal input.

RK-80 series: Designed for basic applications, this series offers the same compact form factor as the R4K-80 but features a simplified 3-digit display and control interface.

P4KF-80 series: The next generation of the R4K-80 series. Maintaining the slim 35 mm width, this series offers improved rise time performance and reduced ripple noise.

TB series: Available in 360 W, 720 W, and 1080 W models. The TB series features a Turbo function (wide-range output), allowing it to handle voltage and current ranges equivalent to three conventional fixed-range power supplies.

RK series: High-power DC supplies engineered for low-noise performance. Available in three enclosure sizes, many models in this series support wide voltage and current ranges.

PKTS series: A high-power 800 W supply in a compact chassis, approximately 50 mm wide. This modern series offers extensive built-in features and enhanced usability.

All Matsusada switching regulator power supplies feature low-noise designs, making them suitable for sensitive testing and development environments, including QA/QC and prototyping. They are also well-suited for instrument calibration and troubleshooting in both industrial and laboratory settings. With a compact and lightweight form factor, these units are easy to integrate into limited workspaces without compromising performance.
