LED INDICATORS

2 provided are clearly visible up to a 45 degree offset from vertical with office environment ambient lighting. The status is reflected in the

indicator color.

The DC_OK LED LED shall light green if the DC output is within specification, and should be off if the output falls out of specification.

The AC_OK LED LED is green if the AC is within specification and off when out of specification. 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.

PS_INHIBIT/ENABLE Signal 0.0 - 0.5 V contact closure, output OFF (output ON for LCM300U-T-4-401)
