Power Supply Start-up Time and Hold Time Measurement

     JT63 series electronic load has timing measurement function, which can achieve the power supply start-up time and hold time measurement. The trigger can be made either by the voltage level trigger of the current/ voltage rising/falling edge or by the TRI external trigger. The electronic load can count out the time interval of two signals occurring. When the starting trigger signal is made by the TRI external trigger and the ending trigger signal is made by the voltage level trigger of the voltage rising edge, if TRI signal can synchronize the opening of the input AC signal of the power supply, the measurement made at this time is the start-up time of the power supply. When the starting trigger signal is made by the TRI external trigger and the ending trigger signal is made by the voltage level trigger of the voltage falling edge, if TRI signal can synchronize the closing of the input AC signal of the power supply, the measurement made at this time is the hold-up time of the power supply.

Some power supplies have a high requirement to the response time of the power supply programming. At this time, the response time of the power supply programming need to be tested.

JT63 series electronic load has timing measurement function which can test the response time of the power supply programming. The electronic load can make the trigger by triggering the voltage level of the voltage/current rising/falling edge and count out the time interval of two signals occurring. When the starting trigger signal and ending trigger signal are made both by triggering the voltage level of the voltage rising edge, it can measure the rising time of the power supply. When the starting trigger signal and ending trigger signal are made both by triggering the voltage level of the voltage falling edge, it can measure the falling time of the power supply.
