Brand: QSKJ
Model: QS-2448CCBD-600W
Features:
Small size and high power, increase undervoltage protection.
Sampling high-quality aluminum substrate PCB, the heat dissipation effect is very good, and the output power is larger.
The new original chip has stable performance.the input and output are all imported capacitors, with low output ripple, low heat generation and long life.
It adopts imported 100A high-power MOS tube, which has large power margin and good dynamic response.the large-size iron-silicon-aluminum magnetic ring is made of four 0.8 pure copper enameled wires and has low heat and high efficiency.New design with up to 96% conversion efficiency (see the data sheet efficiency conversion curve below for details)
The brand 3296W multi-turn potentiometer has high adjustment precision and small drift.the alloy resistance output current is sampled, and the constant current is stable and the temperature is small.With undervoltage protection, it can effectively protect various batteries and can also be used for solar cells.With constant current function, it can be used for battery car boost, battery charging and so on.With indicator light: power indicator, the working status is clear at a glance.

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.
