Matsusada Precision is a leading company in high-voltage power supply. As a comprehensive power supply manufacturer, products of Matsusada Precision have advantages in size, performance, and reliability.
The world's smallest class combining the space savings and high quality output
The DRJE series is the world's smallest class of sine wave output AC regulated power supply, combining desktop operation with the functionality of the SRA series rack mount multifunction AC power supplies. This is a new type of AC power supply that combines the space savings and high quality output required in testing, evaluation, cell production, etc. While offering high baseline performance and reliability as an AC power supply, outstanding cost performance is achieved through careful selection of the available features. Moreover, with a worldwide input compatible with a wide range of input voltages in a compact chassis, as well as outstanding operability, even novices can begin using it right away, anywhere in the world.
*Not compatible with applications that inject external power into the DRJE series or cause regenerative operation.
As it is a bipolar power supply that uses the switching amplifier method, its volume is approximately one sixth of products that use the linear amplifier method, making it extremely compact. In addition, its compact design with a width of only 140 mm and weight of approximately 5 kg allows it to be used anywhere. It is also equipped with a handle as standard, making it easy to carry.
Capable of a wide range of outputs
Compatibility with various AC input devices enable its use in a wide variety of applications.
Voltage: 0 to 150 V AC/0 to 300 V AC
Frequency: 40 to 400 Hz
Universal type outlet
The front panel is equipped with a universal outlet, convenient for development and testing of products for overseas markets. Plugs for all countries can be used without an adapter.
Large peak current
It achieves a 20 A peak current (in Lo range). It is capable of outputting up to 4 crest factors and is ideal for capacitor input load.
*Constant current output is also available for loads where you wish to limit the current. Contact a sales representative for details.

The DRJE series is not suitable for use with devices that "return generated power to AC lines" or "directly connect to the commercial grid", such as power conditioners used in photovoltaic power generation or fuel cells. For combinations with such devices, please use our high-speed four-quadrant bipolar power supplies.
