How often should the power supply be calibrated?
The PPX should be calibrated by an authorized service center at
least every 2 years. For details regarding calibration, see your local
dealer or GWInstek at www.gwinstek.com /
[email protected].
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.
