DU2L3B158 BOARD
The Power Supply Board (DU2L3B158) of this scanner is a universal feature power
supply, and supports the AC input voltages of 100V to 240V at the rated input.The
Power Supply Board is also equipped with the Power Switch.
NOTE:
Inrush current = 40A (100VAC)
= 30A (240VAC)
Leakage current = 0.25mA or less (100VAC)
= 3.5mA or less (240VAC)
The DC power generated and output is supplied to each mechanism as indicated below.
