External Resistance Control Of Current Output - TEXIO PSW-A Series Instruction Manual

Panel operation
steps Step instructions
1 Connect the external resistance according to the connection
diagrams above.
2 Set the configuration setting when
powering on the F-90 to 2 or 3. (Voltage
setting: external resistance control 1 or
2)
Be sure to cycle the power after the power on configuration has
been set.
3 Press the Function key and confirm the
new configuration settings.
F-90: 2 or 3
4 Press the Output key.
The voltage can now be controlled with
the External resistance.

5.1.4. External Resistance Control of Current Output

External resistance control of the current output is accomplished using the
MIL-26 connector on the rear panel. A resistance of 0kΩ~10kΩ is used to
control the full-scale current of this product.
There are two ways to set the output current (0V to rated current).
External resistance control 1 (Ext-R
Output current = full scale current × (external resistance / 10kΩ)
External resistance control 2 (Ext-R
Output current = full scale current × (1 – (external resistance / 10kΩ))
Ensure the resistor(s) and cables used exceed the
isolation voltage of the power supply. For example:
insulation tubes with a withstand voltage higher than the
power supply can be used.
When choosing an external resistor ensure the resistor
can withstand a high degree of heat.
When using external resistance control, Output ON/OFF
Delay Time (F-01, 02) and V-I mode slew rate select
(F-03) are disabled. Refer to Normal Function Settings on
page 66.
