This module measures the time taken to get to the steady output

voltage of the power supply after the input voltage is applied

(turn on time) and for the output voltage of the power supply to

turn off after the input voltage is removed (turn off time).

Turn on/off time analysis

Power supplies are subject to transient conditions, such as

turn-on and turn-off transients, as well as sudden changes in

output load and line input voltage. These conditions lead to one

of the key specifications of the power supplies: load transient

response. This module measures the load transient response of

the DC output; namely, the time taken for the DC output to

stabilize during a load change.
