High Power DC Electronic Load 63200 Series Operation & Programming Manual
Set Von point. Von is the conduction voltage level when the Electronic Load starts to sink
current and the UUT output reaches the Von voltage. The default setting of Von voltage is
1V.
Set Von latch. There are two operation modes for Von control. Von latch ON means that
Load will sink current continuously when it reaches Von voltage. Von latch OFF means that
Load will stop sinking current when UUT voltage is under Von voltage. The default setting
of Von latch is OFF. Figure 4-4 and 4-5 show the Von LATCH ON and OFF current
waveform respectively.
CAUTION
If Von is set to 0V, the Load circuit will be ON in spite of no UUT. This will get overshoot
spike. If a UUT is applied, the overshoot may damage the UUT even though the Load
current sets small. So, do not set Von to 0V.
