Technical Notes
Products on this catalogue are manufactured on consideration for safety fully as direct current power supplies, but please observe
the Instruction Manual for operation and earth always grounding terminals for safety.
Products on this catalogue are manufactured under the premise that applied on ground potential or in the range of series operation.
Please consult our sales staff when use them on high potential floating.
Products on this catalogue are manufactured on consideration for protection against electric discharge from loads fully, but when
use them for some of continuous discharge like as spattering or for special withstand voltage test, please consult our sales staff in
advance.
We recommend contact our sales staff and inform them your requirement prior to your selection in order to secure safety as power
supply equipment and make your best fit selection.
Connect short with leads of sufficient thickness.
Use PVC wire (105
º
C) which endure enough to
applied voltage. Consideration of ampacity and
limitation for lead wire length by sensing (0.5 V)
requires for wiring to the load.
Good Connection
Unless other wise specified, specifications on this catalogue are
of values at max. rated output (full scale*) after 2 hours warming-up.
Ripple, Stability, Variations and Temp. coefficient are
applied “F.S x Catalogue Value” and Linearity of output,
Linearity of monitor, Linearity of indications are applied
“F.S x value of ±0.5 % (*)” at the applied range of 10 % to
100 % of maximum rated output.
Preset value does not indicate exactly actual output state.
If require exact setting, set voltage value by making
actually output in no-load.
For current, set current value by making gradually current
rise in shorted terminals of output.
Indication is in rms including high-frequency noise.

Series Operation
Parallel Operation
Split Operation
With RKT series of the same model, output voltage and current can be increased by connecting power supplies in series or parallel.
We recommend local control or master-slave control. Do not connect together COMMON of 2 units or more as the COMMON of connector
for external input and output control (TB1) is connected with output.
Sum of output is up to 250 V.
It is impossible to series
operation for one exceeds
250 V in output volt.
Output current is of the min.
one of power supply among
them.
Make all setting voltage
same value. Output current
is sum of each current.
In addition, make OVP level
for all power supplies
maximum to prevent
damage.
Possible to output on
po) or negative (-).
