TTL compatible signal, inhibited when open contact, high or at TTL logic “1”. Signal
referenced to logic return (LRTN)
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.
Internal undervoltage and overvoltage supervision of V
Open collector signal with 20 mA pull-down capability, referenced to logic return (LRTN).
DC fail will go high or open if V

Open collector signal with 20 mA pull-down capability, referenced to logic return (LRTN).
The OC-output will go low 100 ms before an overtemperature 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.
Monitors the output current I
Output voltage trimming V

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.
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)
