The DP series has been meeting diverse testing and evaluation needs with features such as high-quality waveforms, low distortion and noise, and an extensive product lineup that can handle even large capacities.
In addition to the stable output performance of the DP series, the newly released DP020AS allows flexible system
building by combining multiple units. The DP020AS can be easily expanded and rearranged to support efficient operation of power supply equipment according to user's needs.
The increase of the output voltage from 320 V AC to 350 V AC made it possible to handle the overseas power supply
voltage of three-phase 480 V at up to 20% above or below. The output frequency has been increased from 550 Hz to 5
kHz.

 DP020AGS
Simplified model in terms of functions and specifications.
It is suitable for production and inspection.
Major differences between the DP020AS are,
|
|
|
Frequency range :
DC, 1 Hz ~ 550 Hz
|
|
|
External signal input and arbitrary waveform are not available |
|

|
|
| Flexibility to build multi-phase systems easily to meet your needs

• DS020AS can be used as a System Master, Phase Master, and Booster.
|
|
|
The system can be expanded by simply connecting the unit cable to the back of the device.
|
|
|
Up to 2 boosters can be connected per System Master unit (for capacity expansion).
|
|
|
*
Each phase has the same number of units.
|
|
- System Master unit:
Master unit for the entire system
(L1 phase master)
|
|
|
 system I/O (rear)
|
|
- Phase Master unit :
Operated by control signal from the System Master unit (L2 phase and L3 phase)
|
|
|
|
- Booster:
Expand the power capacity of the master units
|
|
|

Example of system building
|
|
|
|
| Possible to build multi-phase systems
|
|
It is not necessary to reconnect cables when changing output phase configuration.

High quality output
|
|
|
|
| Capacitive load output wave example (636 uF)
|
The output is stable even with large capacitor loads,
where the power supply output is prone to oscillation
or distortion.
Output of DP020AS is stable under various loads.
|
|
| Rising / Falling waveform
|
|
|
Compared to general AC power supplies, the rise time is shorter and it is possible to generate fast change waveforms with high reproducibility. It is suitable for reproducing transient response.
