4.1 REMOTE ON/OFF CONTROL
The power supply is turn on/off by TTL signal.
Remote On/Off Signal Characteristics
4.2 AUXILIARY +5Vsb
This power supply is specifically equipped with an independent stand-by +5V
output current, 2.0A max. This output will always provide +5V except when
the AC line is cut-off.
4.3 AUTO RESTART
If the power supply's output dropped out of the regulation, which is caused by
AC line Voltage, the power supply will automatically resumed normal operation
only after the AC line voltage returns to the specified operating range.
