Four-quadrant fast response
bi-polar power supply
DJOP series is four-quadrant bi-polar power supply which source and sink electric power. They can be used in 2-mode of a
constant voltage (CV) or a constant current (CC). Thanks to the original design, phenomenal light weight and compact size power
supply, which is 140mm width, and weigh 3kg has been achieved. They are ultra compact and high speed, driving output propor-
tional to the input waveform such as a sine wave, triangular wave, saw wave, and square wave. All the models are completely
solid-state with output voltage between ±10V to ±60V.
DJOP series is most appropriate for evaluation test such as solar panels, the instruments driven by battery and the IC which
control battery.
Even faster model, DOS series, amplifier with function generator,
DOPF series, or more high power model, DOP series, are available.
Contact to local sales office for details.

High speed over current protection
DOP series is provided with 2 types of over current protections, high speed over current
protection to limit the pulse current, and standard over current protection to limit the
static current.
The standard over current protection limits the static current, responding at around 1ms.
Additional high speed over current protection can limit pulse current of square waveforms
or from capacitor at approx. 2 times more current of rating.
DOP series is equipped with over voltage protection, which
protects load by limiting voltage up to approx. 120% of the
rated output voltage even at abnormal conditions.

Over voltage protection (O.V.P)
DOP series is also equipped with over current protection,
which protects power supplies and load by limiting current
up to approx. 120% of the rated output current.
Over current protection (O.C.P)
*-LVl option(output voltage limitter) enable to control the output in 0 to approx. 110% range. *-LIl option(output current limitter) enable to control the output in 0 to approx. 110% range.

When ordering, suffix the following option mark to the model number.
<e.g> DJOP60-1-LDS (Alphabetical order)
Rise time
Capacitative load
Capacitative load may cause oscillation.
In such cases, placed a power resistance in series with the output.
Be careful that the frequency bandwidth is limited depending on the resistance and
capacitance placed in series when capacitative load.
Inductive load
Some inductance of inductive load may cause resonance in CC mode.
In such cases, connect a C-R series circuit between output terminals to prevent resonance.
Response speed
When accurate output waveforms are required, select a amplifier with a frequency
bandwidth higher enough than the operating frequency.
In case of using sine waves, 3 to 5 times more frequency bandwidth is required, and around
10times more in case of square waves in general. Inadequate bandwidth causes not only
decrease in the output amplitude but much difference between the input and output phases.
Therefore operating the product while monitoring the actual output waveforms is
recommended.
(Stepping time):The response time is sometimes described by the rise time (as shown
in the drawing on the right).
The rise time of an amplifier at a response speed of (= frequency bandwidth) Fc (Hz)
is generally acquired by "tr 0.35/fc."
Fall time tf is the same as tr.
Frequency bandwidth
: at 30kHz or lower, tr = tf = around 12 µs
: at 20kHz or lower, tr = tf = around 18 µs
