Figure 10 Protection Setting
When the output voltage/current is higher than OVP/OCP set value, N3410 will shut
off output, and alarm OVP/OCP will be displayed on the screen. At this time, users
can press
for three times continuously to clear the protection.
When overvoltage/overcurrent protection occurs, please also check whether
OVP/OCP setting value is lower than output voltage/current. If this is not the case,
please contact our authorized distributor or NGI.

Figure 11 Active load wiring diagram
Note: When overvoltage/overcurrent occurs, the protection circuit inside N3410
will shut off output. If an active load such as a battery is connected to N3410
output interface, when overvoltage/overcurrent occurs, the current from the active
load such as the battery is poured into the internal circuit of N3410, which will
damage N3410. To avoid this situation, users can connect a diode in series with the
output interface, as shown in the figure below.
