Working Characteristics:
Operation Guide:
Voltage regulation:
When the power supply is unloaded, use a flat-blade screwdriver to adjust the output "CV-ADJ" potentiometer (marked in the figure below) to increase clockwise and counterclockwise to reduce the output voltage by the output capacitor. When the high voltage is adjusted to a low voltage, the reaction will be slower. The adjustment of the instrument is smaller.
Current regulation:
Adjust the "CC A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the load such as the LED battery, and adjust the "CC A-ADJ" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, it is connected to the output, and adjust the CC A-ADJ to the current you need. When charging, be sure to use the discharged battery to adjust the battery. The more the charge, the smaller the charge current.
New: Enter low battery protection
The low battery protection is mainly for preventing the battery from being over-discharged when the input power is the battery, the power supply module and the battery are damaged when the battery voltage is too low, and the low voltage protection is also set when the input is the switching power supply. Undervoltage protection is 10V.
