Main Negative Output Voltage.
Main Positive Output Voltage.
Supervisory signals: TEMP ALARM, AC FAIL, AUX, DC OK and PS EXIST.
PMBus signals: SCL, SDA and SMB ALERT.
SIGNAL RETURN and mentioned signals are isolated from the output terminals
and -SENSE.
Indicates that Power Supply module is inserted into the shelf. "Active Low".
This output has a built in O-Ring diode.
Not affected by the INHIBIT/ENABLE signal or any other fault.
Negative sense.
The -SENSE signal should be connected to -V on Power Supply or Load side.
PMBus Address lines.
Refer to Section 5.1.3 for Addressing.
Current sharing signal should be connected when Power Supplies are connected
in parallel, to allow accurate current share between units.
Turns ON the main output by electrical signal or dry contact.
ON: 0~0.6v or short; OFF: open.
Input 0~5V. Provides Vout programming by Voltage.
Refer to Section 3.2.5 and Section 3.2.6.
Positive sense.
The +SENSE signal should be connected to +V on Power Supply or Load side.
Turns OFF the main output by electrical signal or dry contact.
OFF: 0~0.6v or short; ON: open.
Requires the "ENABLE" signal to be connected to "Signal Return"
Serial Clock signal.
Refer to Section 5.1.4.
DC OK signal. LOW when the output voltage is higher than 85~95% of set Vout.
Open collector type (15V, 10mA).
Serial Data signal.
Refer to Section 5.1.5.
TEMP ALARM signal. LOW when the internal temperature is within safe limit;
HIGH approx. 10°C below Thermal shut down. Open collector type (15V, 10mA).
Variable output for Voltage programming with PMBus option.
PMBus INTERRUPT signal.
Refer to Section 5.1.6.
AC FAIL Signal; LOW when the input voltage is 85Vac<Vin<270Vac; HIGH when
the input voltage is 85Vac>Vin or Vin>270Vac. Open collector type (15V, 10mA).
AC GROUND. Refer to Section 2.1 for Safety Instructions.
AC NEUTRAL. Refer to Section 2.1 for Safety Instructions.
AC LINE. Refer to Section 2.1 for Safety Instructions.
