Panel Operations
Using the PWX as a CV or CC Power Supply
When the PWX is in CV mode, the set current is the
limit of the current that can flow through the load.
When the PWX is in CC mode, the set voltage is the
limit of the voltage that can applied to the load. If the
limit is reached, the PWX automatically switches the
CV/ CC mode.
1Press SET to change to the setting display.
2Turn the VOLTAGE knob to set the voltage,
Turn the CURRENT knob to set the current.
Voltage range: 0 % to 105 % of the rated output
voltage
Current range: 0 % to 105 % of the rated output
current
3Press OUTPUT to turn output on.
The output turns on and off each time you press
OUTPUT.
Locking Panel Operations (Key lock)
When the keys are locked, the key and rotary knob
is invalid. There are three levels of key lock. Use
CONFIG parameter CF03 to set the level.
●Loc1: Lock all keys except the OUTPUT and
memory A, B, and C keys.
●Loc2: Lock all keys except the OUTPUT key
●Loc3: Lock all keys and the rotary knob.
Hold down LOCK key until the LOCK LED
lights. To unlock the keys, hold down LOCK
key again until the LOCK LED turns off.
To set the PWX to the Factory Default
Hold down LOCK+LOCAL while you turn the
POWER switch on.
Protection Functions
The PMX is equipped with the following protection functions. When a protection function is activated, an alarm
occurs, the output is turned off, and the cause of the alarm is indicated.
Press OCP • OVP key for setting the OVP trip point, the OCP trip point.
There are two methods to clear alarm.
●Press ALM CLR (SHIFT+SET)
●Turn the PMX off, fix the problem that caused the alarm, and then turn the PMX on.
Unless you fix the problem that caused the alarm to occur, the alarm will occur again.
Overvoltage protection (OVP) Activated when the output terminal voltage exceeds the set voltage (OVP trip point).
setting range
10 % to 110 % of the rated output voltage
Overcurrent protection (OCP) Activated when the output current exceeds the set current (OCP trip point).
setting range
10 % to 110 % of the rated output current
Overheat protection (OHP) Activated when the internal temperature rises to an abnormal level.

PRESET
A, B, C
Lights when the memory A, B or C values
are being recalled or saved
Preset Memory Function
You can stores three sets (A, B or C) of the voltage
and the current.
Saving setting to preset memory
To save a preset memory, press SHIFT+the
memory key (A, B, or C) to which you want
to save the settings until their LEDs turn on
(Hold the keys down).
Recalling preset memory entries
1Press SHIFT+the memory key (A, B, or C)
from which you want to recall the preset
memory entry.
※If you hold down, the present values in use will
be saved to the preset memory entry instead.
2Check the displayed settings, and then
press SET.
Measured Value Display and Setting Display
• Measured value display
When the SET key LED is off, the present output
voltage and output current are displayed. You
can change the output voltage and output cur-
rent while the measured value displayed.
• Setting display
Press SET to light its key and display the present
output voltage and output current settings.
Press SET again to return to the measured value
display.
OUT PUT LED
Lights when output is
turned on

External Control
You can use the J1 connector of external control.

remote sensing is not being performed, this is connected to the negative
output.
*2. Open collector output: Max. voltage of 30 V and max. current of 8 mA.
The status common is floating (isolation voltage or less), it is isolated
from the control circuit.
Output voltage control
Set the CV control using an external
voltage or an external resistance in
the CONFIG settings so that external
voltage control is enabled (CF05:VoLt/
rES).
• Control using an external voltage
(Vext)
Use pins : 4, 5
• Control using an external resis-
tance (Rext)
Use pins : 6, 7
Output current control
Set the CC control using an external
voltage or an external resistance in
the CONFIG settings so that external
voltage control is enabled (CF04:VoLt/
rES).
• Control using an external voltage
(Vext)
Use pins : 14, 15
• Control using an external resis-
tance (Rext)
Use pins : 16, 17
Output on and off control
To use an external contact to control
the output on and off states, set the
appropriate CONFIG parameter (CF06:
on)
Use pins : 18, 19
External monitoring
• External monitoring of the output
voltage and output current status
Use pins : 1, 2, 3, 5, 15
• External monitoring of the status
Use pins : 11, 12, 13, 23, 24, 25
For Rext, use a resistor that is rated
at approx. 10k Ω, 1/2 W or greater,
that has a low temperature coefficient,
and that will change little over time.
Examples of such resistors are metal
film or wire wound resistors.
CONFIG Settings
Press CONFIG and use the VOLTAGE knob to select the parameter
that you want to set, and the CURRENT knob to change its value.
：Indicates a parameter that is applied immediately.
r：Indicates a parameter that is applied when the PMX is turned on.
¯：Indicates a parameter that is applied when CF34 is executed.

Sensing
• Local sensing
This method when the
load current is small or
when you do not need to
consider the load effect
voltage.
• Remote sensing
This is a feature that sta-
bilizes the output voltage
across the load by reduc-
ing the influence of volt-
age drops and other ef-
fects caused by the load
cable resistance.
