Benchtop High Performance Programmable AC Power Source
DRS series are well-regulated AC power source realized programmable and high power in unparalleled compact size.
They are a new type of AC power source that has high-quality output combined with the wonder small-footprint size desired in experiments, evaluations or cell production, etc. Despite its compactness, DRS has adopted universal AC input, as well as having a universal output terminal on the front panel, allowing users to operate borderless easily.
In addition, this AC power source is available as standard with a momentary power interruption function, a 32-step programmable internal memory sequence function, and a measurement function. Therefore, it is suitable for testing and evaluating AC input devices during a momentary power failure and input AC instability.
FEATURES AND BENEFITS
- High power of 2 kVA max. in one half rack size of 210 mm width. (DRS2000)
- Distinctive small footprint and weight reduction thanks to implementation of switching amplifying technology, compared to those of the linear amplifying method.
- Momentary power interruption, sequence program, and measurement functions as standard
- The wide range for output voltage (up to 155 V/up to 310 V)
- Peak current is four times of rated one. (crest factor = 4）
- Analog remote control and USB interface are equipped as standard. (applicable to various interfaces by option)
- Programmable and high power in an unparalleled compact size

Note
DRS series are not available to such application that electric power is infused externally or regeneration to behavior is made. Therefore they are not suitable for such devices that "returning generated electric power to AC line" or "being connected directly to the commercial system".
Please make AC output in combination with our high speed four-quadrant bipolar power supplies and such devices.
Functions
Simple Operations and Easy Activation
Pressing "mode" switch allows operation mode to change as follows. (AC mode only)
Local mode → Sequence mode → Instantaneous power failure mode → Setting mode → Local mode
Sequence mode
It is possible to program frequently used wave patterns and output based on it. The test patterns can be set by the operation on the front panel and by the remote control.
- Number of saved program: 3
- Max. step number: 32
- Step time: 1 ms to 999.999 s
- Number of jump: 1 to 999 or limitless
- Operation: Constant, Ramp
- Settable parameters: AC voltage, Frequency, Step time, Number of jumps.
Momentary power interruption mode
is possible to conduct momentary power interruption test of the AC input devices.
It can reproduce the situations where AC input line is unstable or momentary power interruption happens, thus the operating conditions of AC input device (tested device) can be checked under such environment.
Setting time of momentary power interruption
Various Measurement Function
- Output voltage (RMS value, Average value, Peak value)
- Output current (RMS value, Average value, Peak value)
- Output power (Effective power, Apparent power, Reactive power)
- Power factor
- Crest factor
- Keeping peak current value
Selectable Phase at Output ON
This feature allows to select phase when output is triggered on. Output off results in zero cross phase. (sec chart.)
Safety Functions
The DRS series is equipped with a safety function to protect the power supply and connected load. For example, if an abnormal current flows, such as a short circuit, the output is immediately stopped. However, if a load with an inrush current is connected, the output may be stopped by the overcurrent protection function. In this case, use a product with a margin for output current or use the SRK series with a current limit function. Some loads have inrush currents that flow more than 10 times the rated current.
Remote Control
Standard Function and Plenty of Options
As the external control and the USB interface are equipped as standard, they are applicable to automation of production line immediately.
