6-12 6 Hardware
24V Board:
①.Converting the 390V into 24V.The 24V of this board is output under the control of the
Power of the analyzing unit;
②. Transferring AC to the heater and controlling the heater;
12V Board:
①. B12V/10A out;
.② C12V/4.7A out;
.③ The 5V/12V board converts the 390VDC from the PFC board to 12V (10A), 12V
(4.7A) and 5V. The 12V (4.7A) and 5V are controlled by the switch of the analyzing unit;
The structure of the power supply unit make it manufactured and maintained easily;
The power supply unit is cooled by fans;
