FAQ
•
The power supply won’t let me change the mode (C.V. mode ↔ C.C.
mode).
•
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 power supply won’t let me change the mode (C.V.
mode ↔ C.C. mode).
To set the power supply to CC or CV mode, the Function key must
be held when the power is turned on to enter the Power On
Configuration Mode. See page 114.
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.
