4.11 Von Operation
The Von voltage value can be set to control the voltage turn on state for the electronic load. When the input voltage
exceeds the Von voltage value, the electronic load’s input state turns on.
This function can protect a DUT when its voltage goes below a specified level. For example, when testing a power
supply’s discharge, you can set the voltage level for the power supply to begin and end discharging.
There are two different modes of Von operation, set by the Von LATCH parameter. When Von LATCH is disabled, the
electronic load will begin sinking current if input voltage exceeds Von voltage. When the input voltage drops below the
Von voltage value, the electronic load will stop sinking current and the input will turn off.
Figure 4.14 Von LATCH Load’s Working Range
When Von LATCH is enabled, the electronic load will begin sinking current if input voltage exceeds Von voltage. When
the input voltage drops below the Von voltage value, the electronic load will still continue to sink current and the input
remains on.
Setting Up the Von Function
The following is a quick tutorial of how to set up the Von function for your electronic load. In this example, Channel 1
Von is enabled and set to 5 V.
