the front panel indicates normal operation. The LED will flash if in parallel operation V
ok, but the unit is disabled.
Overcurrent signal which can be used for synchronous startup of units in parallel or to
recover from an overload condition. (See application note).
LEDs: DC OK (green), AC OK (green); fan fail and overtemperature (amber)
Contact closure to logic ground ( internal pull-down resistor of 1 kΩ)
TTL compatible signal, inhibited when open contact, high or at TTL logic “1”
Signal referenced to logic return (LRTN)
AC OK & DC OK & no overcurrent & no overtemperature & fans working
Overcurrent on I
Provides a warning that the input power has failed at least 5 ms before the
output falls out of regulation (<90% V
Open collector signal with 20 mA pull-down capability, referenced to logic
return (LRTN). AC fail will go high or open during power fail condition
and will go low when input is within the operating range. A Power Fail
warning will turn off the green AC OK LED.

shutdown. Open collector signal with 20 mA pull-down capability, referenced
to logic return (LRTN). The OC-output will go low 100 ms before an over-
temperature condition shuts down the unit. An amber LED on the front panel
indicates overtemperature or fan fail.
Monitors the voltage V
Accuracy ± 0.45 V over setting range, temperature and load.

Setting accuracy over I
Two fan speed levels automatically set depending on the internal temperature.
The fan speed can be set to full speed or automatic control.
Indicates if the fans are operating or have failed.
