CHAPTER 3. OPERATIONS 4
3.4 Preseing Current Limiting Value (CC)
Switch on the power supply, adjust the output voltage to about 3V, turn o the output terminal with push buon
(8), icon becomes . Short the black and red output terminals and turn on the output terminal by (8), icon
becomes , adjust the current limiting value to your desired value say x Amp by (6) and (7) keypad. Turn
o the output terminal and take out the shorting connection.
The current limiting of power supply has been preset to x Amp for the whole range of output voltage.
3.5 Connection and Operation Procedure
1. Aer checking with the rating label 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. Set the current value to maximum by press (6) keypad 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 o the output terminal by push buon (8) .
6. Connect to your load positive to positive and negative to negative.
7. Turn on the output terminal again and check if display shows (CV).
8. If display shows (CC), either your preset current limiting value is too low or your load requires more voltage
and current. You need to re-access the voltage and current requirement of your load and increase the
voltage or current accordingly until (CV) appears.
3.6 Tracking Output Over Voltage Protection (OVP)
This is to protect the connected load in the event that the output voltage control circuit malfunctions, the
maximum output voltage will not exceed 40% of the adjusted voltage value at the time of the operation.
3.7 Over Temperature Protection
When the temperature inside the power supply becomes higher than a pre-determined value, the output voltage
and current of the power supply will automatically decrease to zero to prevent damage to power supply. When the
temperature inside the power supply returns to about 65C then the power supply will automatically return to
operation again.
