Note:
The surge currents of all outputs can keep 10 seconds maximum .
The output ripple/noise requirements should be met throughout the load range and under
the input voltage from 12Vdc to 20Vdc. Measurements should be made with an
oscilloscope with the 20Mhz bandwidth output bypassed with a connector with a
0.1uF ceramic capacitor and a 10 uF electrolytic capacitor to simulate loading.
The system is full run under auto test.
