keyword=tech - Left Q3 work during polarity change
Verified that the Left Q3 power supply can be turned ON and OFF remotely.
It will accept a set voltage in either local or remote mode, it just
doesn't ramp up. The spare SE20 module was verified to be of similar
wiring to the one currently in the supply. When the spare was installed
the supply responded to the reset button, but not the power on button.
With the spare SE20 installed the supply could be turned on remotely and
it did accept a set voltage while in remote. The supply would not ramp
up. The original SE20 was re-installed. The spare SE20 was tagged and put
on a shelf in the trailer.
