Programming the Overvoltage Protection
E3632A User’s Guide 37
1 Readjust the OVP trip level or the output voltage level.
Lower the output voltage level below the OVP trip point
after pressing
or raise the OVP trip level
by using the knob after pressing .
2 Move to the clear mode.
OVP ON
You will see the above message after pressing
. If you changed the output voltage level,
press the twice. Turn the knob to the right
until the OVP CLEAR message appears on the display.
3 Clear the overvoltage condition and exit this menu.
Now, when you press again, the DONE
message is displayed for a second and the OVP
annunciator will not flash any more. The output will
return to meter mode.

OVP circuit.
NOTE
The power supply’s OVP circuit contains a crowbar SCR, which effectively
shorts the output of the power supply whenever the overvoltage condition
occurs. If external voltage source such as a battery is connected across
the output, and the overvoltage condition inadvertently occurs, the SCR
will continuously sink a large current from the source and possibly damage
the power supply. To avoid this a diode must be connected in series with
the output as shown in Figure 2-1.
