１－４Caution for handling
WHEN TOUCHING LOAD AFTER TURNING OFF A HIGH VOLTAGE
1. Make the setting of an output voltage to zero (0). Turn off the OUTPUT ON/OFF switch.
2. Make sure that the output voltage is zero with the output voltage meter of this unit.
3. Turn off the POWER ON/OFF switch.
4. Ground the output for more than 10 seconds, and make sure that the output voltage is
zero at another HV voltmeter. It is especially dangerous when a capacitive load is
connected or a long cable is attached there to.
5. Make it a rule to touch loads with right hand.
HOW TO GROUND
・For safer operation, be sure to ground the ground terminal of power supply at one point on
the ground.
・Make sure to connect the GROUND terminal correctly as shown above. Improper grounding is
dangerous and may cause an electric shock or damage the power supply.
・In case output short circuit or discharging is expected, use shorter and thicker grounding wire.

１Introduction
1. It would be rather safe if the power supply is operated on an insulation board, which is
withstand the voltage used.
2. Try to handle the power supply or load with your right hand, and try to keep the left hand, for
example, putting it pocket.
3. Ground the output more than 10 seconds before touching the load after turning off the
power supply even long time has past after turning off the power supply.
１－５ Troubleshooting
・In case there is no output voltage
１．Check if the proper input voltage is supplied to the power supply.
・Power supply input voltage, AC100-240V±10%, 50/60Hz single phase
・Control voltage for external voltage control is 0 to +10V
２．Check if the connection of control on the rear panel is correct.
３．Check if the function of option is properly operated.
If “E01”is appears, firstly stop the power supply and contact our sales agent from where you
purchased. Abnormality has occurred in this unit.

３－２ Operation method
1. Upon confirming the connection made with this unit as specified (Refer to 1-4[HOW TO
GROUND]), operate it. Be sure to connect the earth with the ground terminal of the unit.
2. Connect the attached AC input cord with AC input connector on the rear panel (INPUT
AC100V-240V) and plug socket.
3. Connect the interlock. (Refer to P12. 3-4-6 Door switch (Interlock))
4. Turn on the POWER Switch. The unit gets in stand-by mode.
No high voltage is generated on the output terminal when unit is in this mode.
5. Pressing the output voltage/current preset switch and keeping it pressed shows the voltage
and current settings on the display. Turn the output voltage dial to adjust the voltage as
desired. Then turn the output current setting dial to adjust the current as desired.
6. Press the OUTPUT switch to output the set value. The red lamp lights on.
7. For ending the operation of the power supply, be sure to return the output voltage setting
dial to 0 (if the same voltage is to be used again, leave it as it is), turn off the switches in the
order OUTPUT switch, POWER ON/OFF switch.

３-３ Description of Operation Modes
The EPR Series power supply units are provided with two operation modes (constant voltage
and constant current modes) and two control modes (local and remote modes).
This section describes the constant voltage and constant current modes in the local modes.
The operation mode is determined by the following:
・ Output voltage setting V
set
・ Output current setting I
set
・ Load resistance
R
L
3-3-1 Constant Voltage Mode
The power supply unit operates in the constant voltage mode when the load current
I
L
is less
than the current setting I
set
( I
L
< I
set
; I
L
= V
set
/ R
L
).
In the constant voltage mode, the voltage is constant at the set value ( V
set
) and the load
current I
L
changes according to the load.
When using the power supply unit in the constant voltage mode, turn the current setting
knob clockwise all the way to the maximum or ensure that it is set to the required current,
which allows setting to the desired voltage.
3-3-2 Constant Current Mode
The power supply unit operates in the constant current mode when the load resistance is
low enough to make the load current
I
L
more than the current setting ( I
L
> I
set
). In the
constant current mode, the current is constant at the set value ( I
set
) and the load voltage
changes according to the load.
R
L
= Load resistance
V
set
= Output voltage setting
I
set
= Output current setting
3-3-3 Crossover Mode
The automatic crossover system functions to automatically switch between the modes as
the load response changes. For example, the mode is changed from the constant voltage to
constant current when the load current exceeds the current setting. The mode is brought
back to the constant voltage when the resistance becomes high enough.

３－４ Other function
3-4-1 Over voltage protection (O.V.P)
This unit has an over voltage protection. Even at the time of abnormality, it is limited at
approx. 110% of the maximum rated voltage, protecting power supply and load from damage.
3-4-2 Over current protection (O.C.P)
This unit has an over current protection. When over current, the output current is limited by
decreasing the output voltage.
3-4-3 Power failure protection
This unit integrates a circuit to stop the output when it is recovered from power failure.
During the operation, when recovered from power failure, unit does not resume the output.
Resume the output by OUTPUT ON/OFF switch.
When power failure protection is not in use, set “0” (OFF) for “4” of starting menu.
(Please refer to 4 for starting menu.)
Then, when recovered from power failure, or when turn on POWER ON/OFF switch, power
supply shall get back to the status when power failure is happened.
(If power is failure when OUTPUT ON/OFF is ON, then the unit resume the output
automatically. When power is failure when OFF, power supply keep off.)

About the operation with the OUTPUT switch on the front panel or a remote switch, and the indication of
OUTPUT LED
The procedure of operation for an output is different with whether the remote switch is set to ON or OFF at
the time of POWER ON.
About the difference arising from the state of the remote switch at the time of POWER ON
When a blackout protection is ON
When the POWER switch is turned off during output preparation or an output, a blackout protection operates.
When the POWER switch is turned on again, it will be in an output halt condition.
① In the case of the remote switch OFF and the POWER switch ON
② In the case of the remote switch ON and the POWER switch ON
*EPR series is high voltage power supply. Therefore, for the safety of users, at the time of factory shipments,
it is a setup switch is not outputted unless the OUTPUT switch is turned on. When a blackout protection is
OFF, output can be done only with the operation of the remote switch even if the OUTPUT switch is not
turned on.

When a blackout protection is OFF
When the POWER switch is turned on again after being turned off during output preparation or an output, EPR
series starts in a state before turning off the POWER switch. An output is started by making the remote switch
short-circuit in an output preparatory
If the POWER switch was turned off during the output, please be careful that the output is reopened
immediately when the POWER switch is turned on again.

3-4-6 Door switch (Interlock)
High voltage output can be cut off with external switch off. For safety reason, once the
output is cut off, the unit shall not resume the output even turning the external switch
back on.
To reset this status, turn the Power switch on after shorting the interlock terminal.
3-4-7 External voltage control
In the remote mode, 0-10Vdc external voltage can control the output voltage within the
range of 0-100%.
