1.7>.The output voltage will decrease due to the current sampling resistor
at the output. The higher the current, the more the voltage is reduced.
1.8>.Output current can not keep fix value output.It changes with load.But
It can not exceed set output current value.
2>.As a charger:
2.1>. Tops: Power supply module can not be used as charger module if it
does not support constant current function. The voltage difference between the
battery with insufficient voltage and the charger is very large. Causes excessive
charging current even damage the battery. So it need keep charging in constant
current mode to reaching a certain level. Then automatically switch back to constant
voltage charging.
2.2>.Make sure floating charge voltage and charge current for battery. If
the lithium battery’s parameter is 3.7V/2200mAh, then the float charge voltage is
4.2V, and the maximum charging current is 1C, which is 2200mA.
2.3>.Connect right input voltage at input terminal.(Note:Please don ’ t
connect load during set parameter).
2.4>.Test output voltage by multimeter and adjust CV potentiometer to
make sure output voltage reach to require floating charge voltage.(If charge a 3.7V
lithium battery, adjust the output voltage to 4.2V)
2.5>.Rotate CC potentiometer counterclockwise more than 10 turns at first.
2.6>.Test Output short circuit current by multimeter at 10A or 20A
(Connect two Test Probes to output terminal on module)
2.7>.Rotate CC constant current potentiometer clockwise to set output
current according to require charge current value.
2.8>.Connect battery at output terminal and start to charging.
3>.As a high power LED constant current driver:
3.1>.Make sure LED working current and maximum working voltage.
3.2>.Connect right input voltage at input terminal.(Note:Please don ’ t
connect load during set parameter).
3.3>.Test output voltage by multimeter at output terminal and adjust CV
potentiometer to set output voltage to LED’s maximum working voltage.
3.4>.Rotate CC potentiometer counterclockwise more than 10 turns.
3.5>.Test Output short circuit current by multimeter at 10A or 20A(Connect
two Test Probes to output terminal on module)
3.6>.Rotate CC constant current potentiometer clockwise to set output
