Parameter
Conditions/Description
Status Indication
LEDs: DC OK (green), AC OK (green); fan fail and overtemperature (amber)
I
2C digital bus
Monitors alarm functions and sets parameters
PS present pin
Contact closure to logic ground ( internal pull-down resistor of 1 k)
PS remote shutdown / Inhibit pin
TTL compatible signal, inhibited when open contact, high or at TTL logic “1”. Signal
referenced to logic return (LRTN)
Power supply OK (I
2C)1
AC OK & DC OK & no overcurrent & no overtemperature & fans working
DC current fail (I
2C)1
Overcurrent on Io1
AC fail / Power down warning
(I
2C & OC)2
Provides a warning that the input power has failed at least 5 ms before the output falls out
of regulation (<90% Vo1 set).
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.
DC fail / Output voltage fault
(I
2C & OC)2
Internal undervoltage and overvoltage supervision of Vo1.
Open collector signal with 20 mA pull-down capability, referenced to logic return (LRTN).
DC fail will go high or open if Vo1 is < 90% or > 110% of Vo1 set, measured in front of the
ORing FETs.
A green LED on the front panel indicates normal operation.
The LED will flash if in parallel operation Vo1 is OK, but the unit is disabled.
Temperature warning (I
2C & OC)2
I
2C critical temperature warning: Indicates that the operating temperature has reached
[Tshut-down – 10K]
I
2C & OC overtemperature warning: Indicates if the unit is in overtemperature 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 overtemperature condition shuts down the
unit.
An amber LED on the front panel indicates overtemperature or fan fail.
DC voltage monitoring (I
2C)1
Monitors the voltage Vo1 at the output connector.
Accuracy ± 0.45 V over setting range, temperature and load.
DC current monitoring (I
2C)1
Monitors the output current Io1 : Accuracy ± 0.4A over the load range.
DC voltage trimming
(I
2C or external resistor)1
Output voltage trimming Vo1: ± 8 % of Vo set
Setting accuracy over I
2C: ± 50mV at Vo nom, ± 150 mV over setting range
Fan speed control (I
2C)1
Two fan speed levels automatically set depending on the internal temperature.
The fan speed can be set to full speed or automatic control.
Fan OK (I
2C & OC)2
Indicates if the fans are operating or have failed.
Synch. startup pin
Overcurrent signal which can be used for synchronous startup of units in parallel or to
recover from an overload condition. (See application note).
1 Detailed I2C information is available from the model’s I2C Manual found on the Power-One web site.
2 Provided over the I2C interface and as an open collector signal on the output connector (OC).
