EX Series Operating Manual
If the real output current is higher than OCP level value, "
OCP TRIPPED
" message
appears on the display. And output voltage and current is dropped to near zero.
In other to output the voltage and current, at first remove the DUT from load wire and clear
the tripped OCP as like below method. The reason of tripped OCP occuring,
First, OCP setting level is lower than rear output current level. Therefore, increase the
OCP level.
Second, Maybe the DUT is like a coil, motor and as like a source that make an in rush
curren.To avoid this, a UF-diode must be connected in series with the output as
shown below.
Third, In case of using the DUT as like source. If external voltage source such as a battery
is connected across the output, feedback current level is higher than OCP level and
it occurs tripped OCP. A diode must be connected in series with the output as
shown below.
Forth, If you can't control the tripped OCP, turn off the OCP function.
Enter the "Factory mode" and move to "6
.OCP USE
" and then disable this function.
