3. POWER SUPPLY (Buy in power board)
3.1 Setup the AC I/P at 90VAC, add 2.6A loading to +12V O/P and DC
O/P voltage is 12V +/- 1.2V, 1A loading to 3.3V O/P and DC O/P
voltage is 3.3V +/- 0.165V, 1.5A loading to 5V O/P and DC O/P
voltage is 5V +/- 0.5V (B).
3.2 Check voltage at 3.3V O/P should be within the range 3.3V +/-
0.165V. 5.0V O/P should be within the range 5.0V +/- 0.5V
12V O/P should be within the range 12V +/- 1.2V (B)
