LED INDICATORS
2 provided are clearly visible up to a 45 degree offset from vertical with ofce environment ambient lighting. The status is reected in the
indicator color.
The DC_OK LED LED shall light green if the DC output is within specication, and should be off if the output falls out of specication.
The AC_OK LED LED is green if the AC is within specication and off when out of specication. Note: With 5 V standby, Green also
indicates that PSU is in standby mode/output off.
CONTROL SIGNALS
AC_OK Open collector 0.5 V maximum at 10 mA. Both emitter and collector access provided.
DC_OK Open collector 0.5 V maximum at 10 mA. Both emitter and collector access provided.
