Ultra-Compact Benchtop AC Power Source

Achieves excellent cost performance

  • AC:
    0 to 150 V, 0 to 300 V
    500 VA/40 Hz to 400 Hz
  • Space saving
  • Outstanding cost performance
  • Universal outlet

The world's smallest class combining the space savings and high-quality output

The DRJE series is the world's smallest class of precision sine wave output, combining benchtop operation with the functionality of the SRA series rack mount multifunction AC power sources. This AC power source is a new type of AC power source 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 source, outstanding cost performance is achieved by carefully selecting 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.

Main Applications

  • Experiments
  • Endurance testing
  • Evaluation and testing of AC-powered devices

Ultra-compact design

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.

Ultra-compact design

Capable of a wide range of outputs

Compatibility with various AC input devices enables its use in a wide variety of applications.

  • Voltage: 0 to 150 Vac/0 to 300 Vac
  • Frequency: 40 to 400 Hz

Universal type outlet

The front panel is equipped with a universal outlet, convenient for the development and testing of products for overseas markets. Plugs for all countries can be used without an adapter.

Universal type outlet

Maximum 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.

Maximum peak current
* 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 solar inverters (PV inverters) used in photovoltaic power generation or fuel cells. For combinations with such devices, please use our high-speed four-quadrant bipolar power supplies.
