The external DC power supply must be able to withstand up to 10 A of “in rush
current” for a few microseconds.
The 15 V to 24 V requirement is the voltage needed at the
DC
IN
connector site. The
length of the cable has an impact on the power supply’s nominal value. For example,
with a nominal value of 15 V and 30 meters of cable, the voltage at the connector site
could be lower than 14 V which is too low for the instrument to start up.
