1 Introduction
1-1 Greeting
Thank you very much for choosing our R4K series.
We expend every possible means to assure the quality of our products. To maximise performance and
ensure safe use, please handle the product appropriately in accordance with this Manual.
Although we have created this Manual with care, please kindly contact us if any ambiguity, errors or
omission is found.
1-2 Overview
R4K series power supply generates wide range of variable output voltage and current with high stability,
which is required for various applications such as test for components (LCD, semiconductors and etc.) or
system power supplies.
With high frequent switching technology, R4K series enable high power and low noise output in such a
compact body.
Further, the –LDe option adds output options including the pulse sequence function that repeats on
and off and the lamp/sweep function that arbitrarily sets rising/falling time, allowing our customers to
change the output state according to their own environment.

The power supply has protection for intermittent short circuit, however operation with repeatable
short circuit with arc should be avoided.
The power supply has enough protection for noise, however if hung-up or voltage output, which is
not programmed, are observed, turn of the power supply and reset the but, then resend the
command again from controller.
Any system change shall be done while the power of all the equipments of system is turned
off. Sometimes it prevents the unit to function properly that causing of high voltage.

2-4-2 Ventilation
There are inhaling and exhalation holes on upper and bottom side of power supply for cooling.
Please hare enough room for air flow and operate it in good ventilation condition.
(When the temperature rises 10℃by theArrehenius law has been said that life halved.)
Make a flow of air around it, Lower the power supply internal temperature use.
When removing the plastic foot, please secure a space of more than bottom 8mm.
Side space (about 50mm) at a windless place, Side space (about 10mm) at a Windy place
(At forced air cooling by a fan), please reserve space.
Remove dust accumulated on inhaling holes.
Such dust might prevent air cooling and cause failure.
MUST

2-6 Connection
It is important to have correct connection and grounding in order to use R4K series power supply with
high performance, high reliability and low ripple.
2-6-1 Connecting with load
Use leads of sufficient thickness and make them as short as possible.
Use PVC cable that has enough resistance to the voltage used (resistant to 105 deg.C).
Wiring to loads requires taking into consideration the current capacity of the wire and the limitation
to the length of output wire by sensing .
Maximum current for rear panel output terminal is 3A per terminal.
When the current is over 3A, output by using monitor terminal on front panel.
When using a inductive load, insert a rated diode which has higher output voltage and current of the
power than those of the output voltage of the power supply to protect the power supply from the
kickback of the load.

・Desorption of the electric wire, please turn off the power.
・An electric wire range outside line material shall not be connected.
・The coating of the electric wire to peel off the length of the specified.
・The use of a single the electric wire to one of the insertion opening,
when you connect two or more, it will be the cause of the failure.
・Desorption of the electric wire is done by holding down the button to the lower limit.
In addition, the electric wire, please fully inserted until the end.
・High temperature, low temperature, humid environment, environment in which the occurrence of
condensation and freezing, environment exposed to direct sunlight, environment exerted vibration
or shock, dust-rich environment Water, various types of oil, (including detergent) chemicals,
can not be used in corrosive gas consuming environment.
・The diameter of the electric wire, but you have to display the cross-sectional area, when mm2

2-6-3 In case of connecting load which has frequent discharge
When connecting to a load which has large ripple current such as plasma discharge, it could affect the
lifetime of the power supply, and recommend to have a protection such as putting low pass filter between
power supply and load as shown below.
When used for a load which has arc or short circuit of faster than 1 per second without such additional
protection, there is a possibility of smoke or liquid leakage from power supply. In such case contact our
sales office for a solution before operation.

2-6-4 When connecting to a capacitive load with energy
When connect to a capacitive load with energy such as battery, there shall be current flow from load to
inside circuit of power supply, which can damage the power supply or cause the shorter lifetime of power
supply.
In the R4K series, besides the case where the diode is not connectable in series or where that is
connected in series, the suction current function of the body turns off by turning on the NSC (Not Sink
Current) switch of starting menu. Note that fall time becomes slow when turning output off.
(Please refer to 5-4 for starting menu.)
Selecta protection diode to protect load or powersupply from countercurrent with following criteria.
Selecta diode with reverse voltage rating is 2 times more than rated output voltage of power supply.
Selecta diode with rated currentis 3 to 10 times more than rated output current of power supply.
Selecta diode with less loss.
Consider the heatof protection diode for countercurrent. Poor heat dissipation can burn the protection
diode for countercurrent connected.
Operation with remote sensing function is not possible.
