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 order 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 current.
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.
▌
When occurs OCP trip, "OCP TRIPPED" message appears on the display
▌
In order to clear tripped OCP, increase the OCP Level.
LCD Display
Protect> 1.ovp
▌
Press the right cursor key in other to enter the OCP.
LCD Display
PROTECT> 2.OCP
▌
In the "protect> 2.ocp ", press the "Protection" key one more time.
LCD Display
OcP SET> 50.00a
▌
Move the under bar cursor where you want to change the level.
▌
Re-adjust the OCP level by using the encoder knob.
▌
Finished to change the level, press the "Protection" key.
LCD Display
CHANGED
After displayed above message, return to before state that tripped OCP.
