Benchtop High Performance Programmable AC Power Source

DRS series is a well-regulated programmable AC power source featuring high power in an 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 devises 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 devises.

Momentary power interruption Mode

It 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
