Models
| Model | Lo range (0 to 150 V) |
Hi range (0 to 300 V) |
|
|---|---|---|---|

| Maximum output current | 5.00 A | 2.50 A | |
Note:
The DRJE series is not designed for regenerative loads (devices that return power to the AC line) or for grid-connected applications such as solar inverters. For these applications, please refer to our high-speed four-quadrant bipolar power supplies.
Functions
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 5.5 inches (140 mm) and a weight of approximately 5 kg allows it to be used anywhere. It is also equipped with a standard handle, making it easy to carry.
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 Hz to 400 Hz
Universal Type Outlet
The front panel is equipped with a universal outlet, convenient for the development and testing of products for international markets. Plugs for all countries can be used without an adapter.
Large Peak Current
High Peak Current Capability The DRJE series delivers a peak current of up to 20 A (in the Lo range). It supports a crest factor of up to 4, making it ideal for capacitor-input loads and other devices with high inrush currents.
Safety Features
The DRJE series includes comprehensive safety features to protect both the power supply and the connected load. The output shuts down immediately if an abnormality, such as a short circuit, is detected. Note on Inrush Current: High inrush currents may trigger the overcurrent protection and stop the output. If your load requires high inrush current, we recommend selecting a model with a higher current rating or using the SRK series, which features a current limit function.
Some loads have inrush currents that flow more than ten times the rated current.
