Set Over-Voltage Protection - Cal Power IT-M3400 Series User Manual

6.1 Set Over-Voltage Protection

Over-voltage protection function allows the user to enable the protection and
set a over-voltage limit (Level) and delay time (Delay). This function prevents
the output voltage from being higher than the limited output voltage and
protects the connected DUT so it this is not over-voltage and possibly damaged
due to an excessive voltage.
An over-voltage protection will occur if:
•
Enable OVP;
•
The output voltage value is greater than the set voltage protection point
Level and the period is greater than the set protection delay time Delay.
Enable OVP
1. Press [Shift]+[R-set](Protect) to enter Protect menu interface.
2. Rotate the knob to select OVP and press [Enter] key to confirm.
3. Rotate the knob to select On and press [Enter] key to confirm.
4. Rotate the knob to adjust the over-voltage limit Level and press [Enter] key
to confirm.
5. Rotate the knob to adjust the delay time Delay and press [Enter] key to
confirm.
6. Press [Esc] to exit.
Delay Time
You can specify an OVP delay to prevent momentary output settings, DUT and
status changes from tripping the over-voltage protection. In most cases these
momentary conditions would not be considered an over-voltage protection fault,
and having an OVP condition disable the output when they occur would be a
nuisance. Specifying an OVP delay lets the OVP circuit ignore these
momentary changes during the specified delay period. Once the OVP delay
time has expired and the over-voltage condition persists, the output will shut
down.
