What is hold up time
It is the amount of time, measured in milliseconds that a power supply unit (PSU) can maintain output within the specified voltage range after a loss of input power. The hold-up time is the amount of time that the system can continue to run without resetting or rebooting during a power interruption.
Test Setup:
- Connect the 6813B output to PSU’s AC input
- Connect the 6813B Trig Out to scope’s channel 1
- Connect power supply output to scope’s channel 2
- Setup scope to negative edge trigger, trigger source = channel 1
- Setup 6813B AC Power analyzer to supply proper AC voltage to PSU, turn on the PSU.
- Connect 6813B to computer/PC using GPIB cable.
Command to be send to 6813B
- -> *RST
- -> VOLT 240;outp on //turn on the PSU @ 240Vac
- -> volt:mode step; volt:TRIG 0 //Setup 6813B to step mode, and set output voltage to 0V when trigger is fired
- -> trig:sour bus
- -> outp:TTLT:STAT ON //enable the Trigger Out
- -> INIT:SEQ1
- -> *TRG
