§ Over current protection
All outputs (+24VDC, +5VDC, +3.3VDC) of LV/HVPS stop outputting when short circuit occurs with
earth or ground.
When the power of the printer is turned off after releasing short-circuit and the power is turned on after
a certain duration passes, each output recovers.
When current exceeding 16A flows, over current protection reacts for each output.
§ Over voltage protection
All outputs of LV/HVPS stop outputting when over voltage occurs.
Operating voltage of over voltage protection for each output is as shown below.
+24VDC: 36VDC
+5VDC: 7VDC
+3.3VDC: 5VDC
