*1. During remote sensing, this is the negative (-S) of sensing input. When
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.
¯

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.
