Input Control

Turn On/Off the Input

Once you power on the load, it will not sink the current immediately, and you need to

press the ON/OFF key to control the input of the load. When the input of the load is

enabled, the ON/OFF key is illuminated. At this time, when the load reaches the

starting voltage (Von), the load starts to sink the current. Then, "LOAD" at the top of

the main interface is highlighted and active. When the input of the load is disabled,

the ON/OFF key is not illuminated. At this time, the load stops sinking the current.

Then, "LOAD" at the top of the main interface is inactive and grayed out.

Von Latch Function

When the load is used to test the power supply product whose voltage rises or falls at

a relatively slow rate, latched protection may occur. The load provides the Von Latch

function. You can set Von to control the sinking function of the load, thus protecting

the DUT. The starting voltage is set in CC, Battery, OCP and OPP modes. The default

unit for Von is V, and it ranges from 0 V to 150 V.

 Enable the Von Latch Function

When the input voltage is greater than the set starting voltage (Von), the load

starts to sink the current. When the input voltage decreases and reaches below

the set starting voltage (Von), the load will not stop sinking the current. As

shown in Figure 2-44.

Tip

Enabling or disabling the input does not affect the set values of the current

parameters.
