Current Sink Function
Function
Description
When the test circuit is an active circuit, and the
manifested voltage in the test circuit is greater than
the output voltage of the power supply, the power
supply will automatically disipate current from the
external power supply. When this function is in the
normal operating state, the power supply outputs
the setting voltage, which is equivalent to a
constant voltage load rather than constant current
load.
The current disipation from the power supply
output flows from the positive terminal out to the
negative terminal. The amount of current sunk is
not controlled from the power supply.
Connection
Connect the positive terminal of the external power
supply to the positive terminal on the high-speed
power supply. Connect the negative terminal of the
external power supply to the negative terminal on
the high-speed power supply.
