increase the value. Long press right button again to save and exit setup mode.
3>.Calibrate output current:
Long press right button when display output current into calibrate output
current, then the screen will flashing.
Short press left button to decrease the value, short press right button to
increase the value.
Long press right button again to save and exit setup mode.
6.Protective function:
1>.Over-Voltage Protection: Module will turn OFF output voltage automatically
if output voltage is more then 30.5V.
2>.Over-Current Protection: Module will turn OFF output automatically if output
current is more then 2A.
3>.Over-Power Protection: Module will turn OFF output automatically if output
power is more then 15W. It will display ‘-OP-’. User need reduce load power
and then press ‘ON/OFF’ button.
4>.Current error: Large display error when output current is less than 0.05A. It
can not display output current if current is 10~40mA.
5>.Over Temperature Protection: Module will turn OFF output automatically if
temperature is more then 100℃. It will display ‘-OT-’. User need reduce load
power and then press ‘ON/OFF’ button.
7. Using Steps:
1>.As an ordinary step down power module:
1.1>.Connect right input voltage at input terminal;
1.2>.Adjust CV constant voltage potentiometer to set output voltage
according to require.Rotate CV potentiometer counterclockwise more than 10 turns
if the output voltage can not be adjusted.
1.3>.Rotate CC potentiometer counterclockwise more than 10 turns at first.
1.4>.Test Output short circuit current by multimeter at 10A or 20A (Connect
two Test Probes to output terminal on module)
1.5>.Rotate CC constant current potentiometer clockwise to set output
current according to require over-current protection value.
1.6>.Test and using(E.g:Module’s maximum output current is 1A if display
1A on multimeter.Red LED indicator will turn on if output reach to 1A.Otherwise LED
is OFF.)
