FAQ

• The OVP voltage is triggered earlier than expected.

• Can I combine more than 1 cable together for the output wiring?
• The accuracy does not match the specification.

The OVP voltage is triggered earlier than expected.

When setting the OVP voltage, take into account the voltage drop
from the load cables. As the OVP level is set from the output
terminals and not the load terminals, the voltage at the load
terminals may be slightly lower.

Can I combine more than 1 cable together for the output
wiring?

Yes. Cables can be used together (in parallel) if the current capacity
of a single cable is insufficient. However the withstand voltage
should also be taken into account. Ensure the cables are twisted
together and are the same length.

The accuracy does not match the specification.

Make sure the device is powered On for at least 30 minutes, within
+20°C ~ +30°C. This is necessary to stabilize the unit to match the
specification.
