Note: AWG (American Wire Gage), that is X line (the mark is on conductor). The above
list is the load flow of a single conductor when it works on temperature 30
℃
This is for your reference only.
2. Power supply can not be set as CC mode
Power supply with constant voltage/constant current can automatic switch. Through this
function, the power can maintain uninterrupted operation while the load change and
produces constant voltage mode to the constant current mode conversion.
In view of the current load, the power supply working in constant voltage mode, it will
provide a controlled output voltage which output voltage drop constant along with the
load resistance decreasing, until the current increase and limited to the default current
value, and then conversions. By this time,the power supply into constant current output
while the output voltage will scale reduce which is according to the load resistance get
smaller.
When the current value is less than set value, power go back to constant voltage mode.
The power supply’s work mode can be indicated by the mark area of VFD. If the
VFD displays CV, the power supply IS in the constant voltage mode. If the VFD
displays CC, the power supply is in the constant current mode.
3. Test battery , how to prevent flint when Joint battery
？
when Joint battery,it strikes fire that is because power supply positive and negative
terminal capacitance discharge. The method of avoiding flint as follows: Please
connect a switch to the wire, and parallel a charging current limiting resistor to the
