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:

    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

 Operation details                                               LCD display

  Step 1         Press “I-set”                                                                           ENTER PASSWORD

  Step 2         Enter the password ( Or jump to step 4 if the                       ENTER PASSWORD

                     keypad is unlocked)

  Step 3         Press “Enter” button ( it will return to step 2 if your            ENTER PASSWORD

                      password is wrong for reentering)                                                      ****

  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

                      It will return to step 4 for reentering if the current                  NEW= 15.0

                       value exceeds the maximum output current.

         It will exit the setting up current operation at any procedure by press ESC button
