High Voltage power supplies (Chassis Mount/PCB Mount)

High voltage power supply is a power supply circuit that generates high voltage. For details, please refer to the products application "High Voltage Power Supply".

As a leading manufacturer of high-voltage power supplies, Matsusada Precision has realized high-performance high-voltage power supplies with "High power," "Low noise," "High stability," and "High reliability" based on its unique know-how accumulated over many years.

The chassis-mounted high-voltage power supplies and PCB-mounted high-voltage power supplies described on this page are power supplies that convert low-voltage DC or AC into high-voltage DC. Our lineup includes not only module type and on-board type high voltage power supplies, but also desktop and rack mount type high voltage power supplies.

We have a full lineup of high-voltage power supplies that can be used for a variety of applications, including high-precision measurement devices such as PMT (photomultiplier tubes) and MASS (mass spectrometers), medical equipment such as electron beam/ion beam, X-ray tubes, ion pumps and electrophoresis, and analytical equipment (Reference: How to Choose a High Voltage Power Supply - Analyzer Relationship between Analyzer and Power Supply Performances). We support a wide range of applications from research and development to production facilities with a full lineup of products that can be used for various applications.

Caution: High-voltage power supplies generate high voltages and can cause harm to the human body if used improperly. Please refer to "Safety and Usage of High Voltage Power Supply" and use them properly.

When selecting high voltage power supplies Please read before operation


  • Power supplies in this catalog is designed and manufactured with safety of high voltage power supplies, but follow the operation instructions in this catalog for operation, and connect the power supplies to the earth ground for safety.
  • Power supplies in this catalog are, except for 6kV and below models of input/output proportional type, designed on condition to be operated on ground level. Models 6kV and below of input/output proportional type must be operated within the dielectric voltage specified in this catalog.
  • External high voltage applied to power supplies in this catalog can cause power supply failure. Protection circuits are there to protect power supplies from failures, and not for protecting load or devices connected to power supplies. Add required solutions for devices connected to high voltage power supplies if needed.
