Power Distribution Board (PCB) Theory of Operation

Purpose

Line AC voltage is supplied to the F5 fryer from the power cord and then converted to 24 volts DC by four separate power supplies. Four power supplies then independently feed 24 volts DC to the Power Distribution PCB which is used to operate all of the MAP system electronic components. The Power Distribution PCB distributes 24 volts DC from two power supplies for controls (Control Panels and OMS) and two power supplies for logic (PMU or GMU).

(4) Power supplies convert line AC voltage to 24 volts DC
Power supplies feed 24 volts DC to Power Distribution PCB
(2) Power supplies for controls (Control Panels and OMS)
