R4k-80 series is higher performance and next generation model of existing RK-80 series DC variable power supply,
which has been receiving good reputation for its innovative compact size and variable range feature. 4-digit meter and
high resolution D/A, A/D converters are added newly for more precise setting and reading. Needless to say, the
innovative compact size, variable range feature and high operability are remaining same as conventional RK-80. R4K-80
series is the best suitable DC power supply for a variety of applications from laboratory experiment to line productions.

When ordering, suffix the above option number to the model number. <e.g.>R4K-80-LUs1,R4K-80L-LDe,R4K-80M-LDeUs1
When controlling several R4K-80 power supplies via USB, a USB hub will

-LDe: Pulse Ramp Sequence
ta, tb, tc and toff can be set with range 1.0s to 99.9h respectively.
PULSE SEQUENCE
Using the stored voltage and current
setting in each memory of a, b and c
and multi set function, sequence
operation is possible. The setting of
repetition to say nothing of a
continuous driving can be set.
Various different operations, such as
repetition of memory a and b or b ,c
and off, are possible by setting the set
time of memory a, b, c, and/or off to
be 0.0. Thus, it makes this model
suitable for evaluation test or other
applications.
RAMP SEQUENCE
This function controls the ramping up
and down the voltage and current to
the set value (or from set voltage and
current value to 0V/0A). It is
convenient to increase( decrease) the
voltage and current value slowly.
*The Ramp sequence can be selected from [both
set voltage and current], [only set voltage], and
[only set current].
COMBINATION OF
PULSE and RAMP
SEQUENCE
Features of pulse sequence operation
and ramp sequence operation can be
combined for more convenient
operation. In addition, by adding multi
set function, sequence operation can
be operated using stored voltage and
current settings in each memory. The
setting of repetition to say nothing of a
continuous driving can be set. For
example it is possible to slowly ramp
up and down the voltage and current
to the three different settings, and so,
it is useful on various scenes.
Note: The operation accuracy of the timer when sequensing is ±0.5%. Be careful when you use it by the long-term running operation.
t1 and t2 can be set with range 0 to 999s respectively.

[caution]
Total output voltage is to be up to 250V.
Therefore for models with output voltage
of over 250V, series operation cannot be
conducted. Output current is to be the
smallest current of those.
Remote switch terminal is connected to
+output internally, therefore do not con-
nect other remote switch at the same
time.
Please keep all the settings of voltage the same.
Output current will be the summation of each
current.

Please keep OVP level of power supply
maximum to prevent any damage.

When selecting
DC power supply
Products on this catalog have been manufactured with consideration of safety as DC
power supply, however please follow instruction manual for operation and make sure
to ground the ground terminal for your safety.
Products on this catalog have been manufactured on the precondition that they are
used in ground electric potential or within the range of the above series operation.
Please contact our sales staff when using the product for floating of high electric
potential, etc.
Products on this catalog are manufactured with consideration for protection against
load discharge. However for specific experiment or continuous discharge such as
sputtering, product may need discharge resistance between power supply and load
or could not be used at all. Please consult with our sales staff in advance.
We recommend that you contact our sales staff with your requirement before choosing
aproductso thatyoucan getthebest product and the safety as high-voltageequipment
is assured.
Important Notice
"F.S × catalog value(*)" is applied
for ripple, stability, regulations and
temperature coefficient, and "value
if F.S × ±0.5%(*)" is applied for
high-voltage output linearity,
monitor linearity and display
linearity, both in the range of 10%
to 100% of maximum rating output.
Applicable scope of specifications
Specifications in this catalog, except otherwise specified, refer to values when maximum rating output (full scale*) after 2-hour warm up.
Indication is in rms that includes high-frequency noise.
Preset value does not show the actual output status accurately. If
you need an accurate setting, conduct actual output without load
and set a voltage. Also for setting current, conduct output after
shorting the output terminal and gradually raise current before
setting at a desired value.
