Constant Voltage Output
DP1308A provides two kinds of output mode for each channel including Constant
Voltage Output (CV) and Constant Current Output (CC), which is depends on the
specified voltage and current as well as the loads carried by the instrument. The
instrument will not output voltage or current beyond setting value. In CV mode, the
output voltage equals to the specified value and the output current equals to the
specified value in CC mode.
For example:
Choose the +6V channel; set the voltage to 6V, the current to 5A and the load to 5Ω
separately.
Because 5Ω× 5A=25V>6V and 6V/5Ω=1.2A<5A, so the Constant Voltage Output of
the channel is 6V, 1.2A.
Operation Steps:
1. Power on
