DRJE series

Ultra-Compact Size Desktop AC Power Supply

Achieves excellent cost performance

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

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.

Main Applications

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

Models

Model Lo (0 to 150 V) range Hi (0 to 300 V) range
DRJE500 Maximum output power 500 VA
Maximum output current 5.00 A 2.50 A

Note

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.

Features

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 enable 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 development and testing of products for overseas markets. Plugs for all countries can be used without an adapter.

Universal type outlet

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.

Large peak current
* Constant current output is also available for loads where you wish to limit the current. Contact a sales representative for details.
