Power Input
AC main power input:
This is a AC main input with bias
±
15%. It supports multiple rated voltages configuration with
100V/110V/120V/200V/220V/230V/240VAC (RMS).
Secondary side of main transformer:
Another input comes from the secondary side output of main transformer. The rated voltage is 220V (RMS)
and 28V (RMS) for up-down board and mainframe.
Power On Board
+24V
When the main input power is ok with no gross over and under voltage condition, the relay K6 is activated
and the AC voltage of secondary side of start_up transformer (BT2) is applied at the D7 (2W06), then the
rectified DC voltage connected to the input pins of U4 (LM317T) and the output voltage is about +24VDC by
the configuration of R10 and R8. The +24V voltage is mainly to drive relays and get other necessary DC
power on board.
VCC_+12V
To make sure the WKS on/off control relay (K7) work properly in AC main power lost condition, the VCC_+12V
DC power use dual power method by the simple parallel of 12V and +12V. 12V is
connected the +12V power from computer and +12V is generated from the conversion of low dropout
regulator LM2940CT-12(D26).
+10V, +5V, +3.3V
To get more accurate voltage reference in voltage comparison circuit, the +10V power is achieved by the
+10V precision voltage reference REF01SC3 (D9).
+5V power is generated by the LM2940CS-5.0 (D8) and +3.3V power is generated by the LM1084-3.3.(U5)
