Description
Main Negative Output Voltage
Main Positive Output Voltage
Return for the following control signals: ENABLE, INHIBIT;
supervisory signals TEMP ALARM, AC FAIL, AUX, DC OK, PS EXIST;
and PMBus signals: SCL, SDA, 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" when connected to SIGNAL RETURN.
11.2~12.5V Auxiliary Voltage Output referenced to SIGNAL RETURN. The
maximum load current is 0.5A. This output has a built in ORing diode, and
is 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 the PMBus interface description HFE
Instruction Manual Chapter 3.
Current sharing signal should be connected when Power Supplies are
connected in parallel to allow accurate current share between units in
Parallel operation.
Turns ON the main output by electrical signal or dry contact (0~0.6v or short).
Input (0~5V) referenced to –S. Provides Vout programming by Voltage.
Refer to Instruction Manual Chapter 1.5, 1.6 & 1.7
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 (0~0.6v or short). SIGNAL RETURN
Serial Clock signal.
Refer to the PMBus interface description HFE Instruction Manual Chapter 3.
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 the PMBus interface description HFE Instruction Manual Chapter 3.
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).
5V fix output for standard option unit. Variable when Voltage
programming is done with PMBus option. Refer to Instruction Manual
Chapter 3.
PMBus INTERRUPT signal.
Refer to the PMBus interface description HFE Instruction Manual Chapter 3.
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 connection.
