Hi Everyone, hi @refectio SIR. Sometime when i turn On iphone wth DCPS, the two lights (check the image plz) CC AND CV blinking alternating (both lights) and then turn off.. ITs not happen with all phone, anybody plz explain me what does it mean? I know its mean Constant Voltage And Constant Current, but i dont understand why the light blink with some iphone and with other iphone not blink ??
Your DCPS should be in either CV or CC mode, never both at the same time. So when you set the voltage (let’s say 4.2V), it will stay in CV mode until the current limit has been exceeded; that’s when it will switch to CC mode. Perhaps there is an issue with your power supply, you could try to test it with a dummy load to see how it behaves under “real-world” conditions. You can also use two multimeter to confirm voltage and current through the load. The DCPS you have is an inexpensive model and it is quite possible that it is not behaving in a standard way so I would fully test it. If it tests fine, then whatever blinking light issue is caused by t load, in this case a phone.
