Operations
Basic Mode of Operation
This power supply is designed to operate as a constant voltage source or as a constant current source. Automatic crossover
to either mode of operation occurs when the load condition changes as following:
Constant Voltage (CV), Automatic crossover & Constant Current (CC)
The power supply functions as a constant voltage source (CV) as long as the load current is less than the preset current limit
-
ing value. When the load current is equal to or greater than the preset current limiting value, the power supply will automati-
cally cross over to the constant current mode, voltage will drop, (CC) will show on the LCD display panel and it will operate as
a constant current source.
When the load current drops below the preset current limiting value, the supply returns to constant voltage (CV) mode.
Set the Output Voltage and Presetting Current Limiting Value (CC)
Turning the voltage or current knob to set your desired values.
Quick pushes on the knobs will move the decimal place for fast tuning.
Turn the knob when the desired number column is flashing otherwise you need to repeat quick pushes again.
One quick push on the current knob to see the preset current limiting value.
Aux. output 1 voltage selection
Move the switch (4) at the back of power supply for selection of 3.3 or 5 VDC.
At 3.3VDC setting, indicator (15) is Off
and at 5VDC setting indicator (15) is On.
Connection and Operation Procedure
1. Check the rating label and plug in to AC mains.
2. Switch on the power supply and the LCD display should be on at the same time.
3. The (CV) icon should be shown on the display.
4. Turn to current volume knob (6) to maximum clockwise if you do not require lower Current limiting value, otherwise do the
preset the (CC) limiting procedure.
5. Set your desired output voltage and then turn off the output terminal by push button (7).
6. Connect to your load positive to positive and negative to negative.
