5.5. Adjusting the output voltage and display the preset current limiting value
1.)
Set to the desired values by turning the voltage or current regulator.
2.)
By briefly pressing the buttons will move the decimal place for rough adjustment.
3.)
Turn the knob when the desired decimal flashes, otherwise you have to dial again by a
short press.
4.)
A short press on the current controller and the display will show the current preset
current limit.
5.6. Setting the output current (CC)
1.)
Turn on the instrument
2.)
Adjust the output voltage to approximately 3V
3.)
With the output on/off button the output jacks with switch (3)
4.)
In the LCD display appears
5.)
Short circuit the black (-) and the red (+) output socket.
6.)
Turn ON the output again with the on / off switch (3).
7.)
The LCD display shows
8.)
Now set the desired current limit value with the Current knob (8). (By pressing the knb
you can choose between coarse and fine adjustment).
9.)
Turn off the output and remove the short circuit at the output jacks.
10.) The current limit has now been set to the value you set.
5.7. Overvoltage protection of the output
Output Over Voltage Protection (OVP):
This is to protect the connected load in the event that the output voltage control circuit mal-functions,
the maximum output voltage will not exceed 30% of the adjusted voltage value at the time of the
operation.
5.8. 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 65°C then the power
supply will automatically return to operation again.
