PMX_MULTI
Basic Functions
Using the PMX as a CV or CC Power Supply
When the PMX is used as a constant-voltage power supply, the set current is the limit to the current that
can flow through the load.
When the PMX is used as a constant-current power supply, the set voltage is the limit to the voltage that
can be applied to the load.
If the specified limit is reached, the PMX automatically switches its operation mode. When the PMX
switches its operation mode, the “CV” (green) and “CC” (red) indications in the display area change.
1
Press SET to change to the setting display.
“SET” appears in the display area.
2
Press SELECT to select the channel you want to configure.
The selected channel is indicated with bracketsed.
3
Turn the VOLTAGE knob to set the voltage.
Voltage setting range: 0 % to 105 % of the rated output voltage of each channel
4
Turn the CURRENT knob to set the current.
Current setting range: 0 % to 105 % of the rated output voltage of each channel
5
To set other channels, repeat steps step 2 to step 4.
6
Press OUTPUT to turn output on.
“SET” disappears from the display area, and “ON” appears. When the PMX is operating as a con-
stant-voltage power supply, “CV” (green) is displayed. When the PMX is operating as a constant-
current power supply, “CC” (red) is displayed.
This completes the setting.
Even when the output is on, you can set the voltage and current by carrying out step 3 and step 4 while
checking the actual output voltage or current
(p.26)
.
You can use the CONFIG settings to set the output-on startup state (CF06:
CC
/
CV
)
Set this according to the operation mode that you are using. You can prevent overshoot from occurring
when the output is turned on by prioritizing CV when using the PMX as a constant-voltage power supply
and by prioritizing CC when using the PMX as a constant-current power supply.
When the output is turned on, the internal capacitors are charged. Depending on the set current, the PMX
may enter CC mode for an instant.
