Desktop size Programmable AC Power Source

DRS series are the stabilizing AC power source realized programmable and high power in unparalleled compact size. They are a new type AC power source which 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 universal output terminal on the front panel, allowing users to easily operate borderless.

Moreover, the instantaneous power failure function, the sequence function and the measurement function are installed as standard function and then it is applicable to test and evaluation of AC input devises at instantaneous power failure or under the destabilized input condition.

Features and Benefits

  • High power of 1 kVA in one half rack size of 210 mm width. (DRS1000)
  • Distinctive small footprint and weight reduction thanks to implementation of switching amplifying technology, compared to those of the linear amplifying method.
  • In addition to the sequence function and the instantaneous power failure function, also the measurement function is equipped as standard.
  • The wide range for output voltage (up to 155 V/up to 310 V).
  • Peak current is 4 times of rated one. (crest factor = 4)
  • Analogue remote control and USB are equipped as standard. (applicable to various interfaces by option)
  • High power of 2 kVA max. in one half rack size of 210 mm width. (DRS2000)

Note

DRS series are not available to such application that electric power is infused externally or regeneration to behabior 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.

Instantaneous Power Failure Mode

It is possible to conduct instantaneous power failure test of the AC Input devices. It can reproduce the situations where AC Input line is unstable or instantaneous power failure happens, thus the operating conditions of AC Input device (tested device) can be checked under such environment.

Setting time of Instantaneous Power Failure
Instantaneous Power Failure Mode
It is able to set time of instantaneous power failure with 1 ms unit in 1 ms to 5 s turing the rotary encoder.
