supply (see the table above). In this case, the programmed OVP trip level,
shown in OVP menu does not change!
OVP Clear option is used to clear to OVP condition (for more information
about how you get back to normal mode after OVP level was tripped, please
refer to the next section).
After you select the desired option, a message will be displayed.
If you didn’t change anything of the previous set parameters, the power
supply will display No Change message.
If you did change a single parameter from the previous set parameters Done
message will be displayed.
After one of these messages is displayed for several seconds, power supply
returns to normal mode.
Important note!
If you enter in the OVP menu and no action takes place for approx. 20 seconds,
the power supply will leave the OVP menu. No Change message is displayed
and the power supply returns to the previous state (the state before entering
OVP menu).
If the output voltage value becomes equal or greater than OVP programmed
level and the overvoltage protection circuit is enabled, the power supply will
display:
And the output voltage value will be 0 V (output is disabled).
There are three ways of clearing the OVP condition:
Ø By increasing OVP trip level and clearing the OVP condition
Ø By decreasing the output voltage and clearing the OVP condition
Ø By disabling OVP circuit and clearing the OVP condition
Important note!
When you turn on the power supply, the overvoltage protection circuit is
enabled and the OVP trip level is equal to the one saved in power_up state
(factory setting: maximum available value).
