Power On Status Signal
Power On Status signal indicates a fault condition in the power supply.
Power On Status signal is a TTL output signal at Pin J2.13 with reference
to COM_ISOLATED (Pin J2.2 or Pin J2.6).
During normal operation, the Power On Status signal will be high. If the
output is disabled for any reason, the Power On Status signal will go low.
The following conditions will set the Power On Status to a low level:
•
AC fail
• Over Voltage protection (OVP)
• Under Voltage Protection (UVP)
• Over Current Protection (OCP)
• Over Temperature protection (OTP)
• Foldback protection
• Interlock
• Output Off
• Shutdown activated (rear panel shutdown).
• Internal hardware malfunction
• Fan failure
