Operation Instruction
Step 1. Presetting Constant Current Value.
a. Turn on the power supply, and adjust the output voltage to about 3V by
turning the coarse &/or fine Voltage knobs.
b. Turn off the device.
c. Short the positive °+”and negative “-” terminals using the leads. Then turn
on the power supply. and remove the test lead.
d. Adjust the current to the desired amps by turning the coarse or fine
Current knobs.
Please do not adjust the Current knobs once the current limit has been set as
above. Current limiting has now been set for the whole range of output
voltages.
Step 2. Presetting Constant Voltage Value.
a. Adjust the output voltage by turning the coarse or fine Voltage knobs.
b. Turn off the device.
Please do not adjust the voltage knobs once the voltage has been set as above.
Step 3. Now connect your load: positive to positive and negative to negative.
Note: If the display shows (CC), either your preset current limiting value is
too low or your load requires more voltage or current. You need to adjust your
current and voltage settings using the above steps.
About CC &CV
The power supply functions as a constant vollagefsource (CV) as long as the
load current is less than the preset “urrent limiting value. If the load
current becomes equal to or greater than the preset currant limit, the power
supply will automatically cross over to the constant current mode and the
voltage will drop. (CC} will display on the LED panel indicating the supply is
now operating as a constant current source.
If the load current drops below the preset current limit, the power supply
retums to constant voltage( CV) mode.
Frequently Asked Question (FAQ)
1. Q: When | power it on, the current displays show zero, is it normal?
A: If itisn't connected to a load it should read zero because no current is flowing. This DC power supply requires manual current and voltage settings.
2. Q; How do | get it to stay in constant current mode?
A: CC is attained when the rated set current is exceeded. It would stay in that mode till the current drops back to the preset.
3. Q:How to set the current value without load connecting?
A: Please short the +/- outputs together, set the current, and remove shorting cable. You could also refer to the operation instruction.
4.Q: Does it remember the last settings when turned off and back on again?
A: Yes, because it's on a dial. If you don't adjust it and just flip the on and off switch in the front it will remain the same.
5. Q:How to switch between Constant Voltage (CV) and Constant Current (CC)?
A:The supply will do it automatically. Turn the current down or up to adjust the limit. When the mode CC shifts to CV, the CV indicator light turns on. You can adjust it to any value. It automatically switches to CC when the set current value is exceeded.
