Power Supply Board
The power supply board converts the AC voltage supplied through the power cord to
DC voltage to power the relays and microprocessor. It is an open-frame, dual output
(5VDC and 12VDC) voltage power supply. If the power supply board is not operational
or defective, the LCD Display will not power on, and the biosafety cabinet will not
function.
The power supply board contains an integral fuse rated at 2.5 amps at 250VAC. It is a
5 x 20 mm barrel fuse. See Figure 13-3.
