DRJ series is not available to such applications where electric power is infused externally or regeneration to behavior is made. Therefore they are not suitable for such devises that "returning generated electric power to AC line" or "being connected directly to the commercial system".
In using the devices above, user our high-speed four-quadrant bipolar power sources with sink current function.
Functions
Compact
Since it is a bipolar power supply with switching amplifier method, its volume is extremely compact in approximately 1/6 compared with linear amplifier method. In addition, its compact design with only 5.5 inches (140 mm) width and approximately 5 kg weight allows it to be installed anywhere. The handle makes it easy to carry.
Wide range of output voltage and frequency
DRJ series can be used for various AC input devices. It is also capable of DC output and thus it can be used in various applications.
- AC output
- Voltage: 0 to 150 V/300 V, Frequency: 1 Hz to 550 Hz
- DC output
- Voltage: 0 to +212 V/-212 V/0 to +424 V/-424 V
Momentary power interruption Mode (-LPfl option)
It is possible to conduct momentary power interruption testing of the AC Input devices simply.
It allows to reproduce a circumstance where AC Input line is unstable or subject to momentary power interruption, thus customers AC input device can be simulated to testing under such environment.
When the momentary power failure operation is needed in three-phase output, the model which is equipped with -LPfl option is necessary as the model to be in charge of phase U. Please refer to "Options".
Setting time of momentary power interruption
When this button pressed for more than 1 sec, a display is switched over to the indication which sets the time of momentary power interruption.
It is able to set the time of momentary power interruption with 10ms unit in 10 ms to 5 s by turning the rotary encoder.
[AC output]
Setting time: 10 ms to 5 s
Setting resolution: 10 ms
AC Output ON/OFF in accordance with the input AC supply ON/OFF (-LN option)
This allows users to re-start the power supply output after the input AC supply's recovery from stoppage without pressing the OUTPUT button on the front panel. Thus remote re-activation without touching/accessing the power supply can be realized.
High peak current
DRJ series addresses 20 A peak current (in Lo range).
It can output up to four crest factors and is ideal for capacitor input load.
Universal type outlet
Power supply has the universal output outlet on the front panel so that various types of worldwide plugs can be used without adaptor. This helps users' global product development and testing work ever convenient and borderless.
Various output modes
- Three-phase output
- Single phase three-wire output
- Master/Slave
It is capable of three-phase output, single phase three-wire output and master/slave connection as options.
Three-phase output
It allows three-phase AC testing and evaluation even on locations where only a single phase 100 V/200 V is available. Its space-saving design with 5.51 inches/140 mm x 3 = 16.54 inches/420 mm width even when three-phase output is configured allows it to be used anywhere.
Single phase three-wire output
It is possible to implement testing and evaluation of single phase three-wire even in locations with only single phase power.
Master/Slave
If a power supply of a larger capacity is necessary, it can be used to construct up to 1 kVA by Master/slave connection. (A master unit is connected to a single slave unit.)

Single phase three-wire connection
Single phase three-wire output mode is available.
- It is possible to choose only one from (-L1p3wm, -L1p3ws), (-LPhu, -LPhv,-LPhw) or (-LMsm, -LMss). It is necessary to equip each power supply with every option.
- To use an interface option (-LUs1, -LGb or -LGob), add only to the master unit (-L1p3wm, -LPhu or -LMsm). It is not required for the slave unit.
- If the momentary power failure operation is needed in three-phase output, -LPhu optional model which is also equipped with -LPfl option is necessary. -LPhv or -LPhw optional models need not necessarily be equipped with -LPfl option. However, when the momentary power failure operation is needed in single-phase output, that is, when one DRJ is used alone, -LPfl option is necessary. Therefore, when DRJ may be used alone and asked for the momentary power failure operation, it is necessary to equip each DRJ with -LPfl option.
- When the rigorous examination in accordance with a standard is required, it is necessary to use other bipolar power supplies.
- These options cannot be selected together.
