DC Power Supplies
DC power supplies (also known as AC-DC power supplies, programmable DC power supplies, or benchtop power supplies) are circuits that provide a constant voltage or current. They are broadly classified into linear regulator and switching regulator types based on their control method. 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 designed for 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.
Our lineup includes the ultra-compact R4K-36 series, which fits in the palm of your hand and features our proprietary high-efficiency switching technology. We also offer the ultra-low ripple R4G series (linear type) and the high-power PRTM series (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 (PSX series, Japanese site).
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.
