4.2.7 Load Effect

The load effect mode can carry out loading under 3 different load conditions (10%, 50%,
and 100%), and continue the load for a preset time (5s), and then record the voltage under
different loads. Finally, calculate the load regulation rate Regulation, △V and other values
according to the formula.
Parameter Setting in Load Effect Mode:
Parameter
Rate Voltage
Rate Current
Formula: Vmax=Vdc@Imin, Vmin=Vdc@Imax, △V=Vmax-Vmin, Regulation=△V/Vset
Before the load effect test, input the rated voltage and rated current, and then press ON to
enter the test. At this time, the load will be loaded according to 3 different loads in turn, and
the values of △V and Reg will be detected. During the test, the ON button can be used to
control the load switch.
