2.3.2 Set up current
3600 Series power supply can be set up for a constant current or a maximum current, please see
the following example.
Conditions: voltage=24V, load R=12Ohm, then V/R=2 A, it represents the power supply pro-
vide the load with 2A current. If the current value is set to 2.50A, the power supply works in CV
mode, the actual current value should be displayed on the screen as 2.00A. If the load resistor
becomes lower, the current will increase. When the current exceed 2.5A, the power supply will
change to CC mode, and the output voltage will drop down to maintain the actual current value
to 2.5A.
Set up current procedure as follows:
2.3.3 Enable/disable the output
By default, the power supply is disabled after power on, users can change the output status
by using ON/OFF button. The button is a turnover button. When the original output is ON, press

Step 4 Press “I-set” . Set up a constant current or a maximum SET CURR=0mA
current by using number key or the rotary knob. NEW=3
Step 5 Press “V/A” or “mV/mA” to confirm the set. SET CURR=0mA

value exceeds the maximum output current.
It will exit the setting up current operation at any procedure by press ESC button
