Power Supply
■ Overview
The finisher AC power supplied to this equipment passes through the filter PCB, and the filtered AC power is converted to 24
VDC. The 24 VDC is supplied to the folder control PCB from which it is supplied to the load-related parts (motors, solenoids, fans,
and clutches) as it is or converted to 5 VDC or 3.3 VDC by the DC-DC to be supplied to logic-related parts (sensors).
■ Protection Function
The 24VDC circuits (used for driving solenoids, etc.) on the controller PCB of the connection machine are provided with a fuse
or a motor driver with an overcurrent protective function. The 24VDC input circuit of each controller PCB is also provided with a
fuse which is blown when an excessive current flows.
Power supply unit is provided with an overcurrent/overvoltage protective function to shut off the output voltage automatically when
an excessive current or voltage occurs due to a problem on the load side (e.g., short-circuiting), thus protecting electric circuits.
Each circuit is provided with a fuse which is blown when an excessive current flows in theAC line, thus shutting off the excessive
AC current.
