Negative sense.
The -SENSE signal should be connected to -V on Power Supply or Load side.
Positive sense.
The +SENSE signal should be connected to +V on Power Supply or Load side.
Input 0~5V. Provides Vout programming by Voltage.
Refer to Section 3.2.4, Section 3.2.5 and Section 3.2.6.
Input 0~5V. Provides Current programming by Voltage.
Refer to Section 3.2.7 and Section 3.2.8.
Variable when Voltage/Current programming is done with PMBus option. Refer
to Instruction Manual
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).
DC OK signal. LOW when the output voltage is higher than 85~95% of Vout set.
Open collector type (15V, 10mA).
Turns ON the main output by electrical signal or dry contact (0~0.6v or short).
Return for the following control signals: ENABLE supervisory signals TEMP
ALARM, AC FAIL, AUX and PMBus signals: SCL, SDA, SMB ALERT,
SIGNAL RETURN and mentioned signals are isolated from the output terminals
and -SENSE.
Negative Output Voltage (Can't supply load current)
Positive Output Voltage (Can't supply load current)
Refer to Section 3.2.4.
5V fix output for standard option unit.
AC FAIL Signal; LOW when the input voltage is 85Vac<Vin<270Vac;
HIGH when the input voltage is Vin<85Vac or Vin>270Vac.
Open collector type (15V, 10mA).
Current sharing signal should be connected when Power Supplies are connected
in parallel to allow accurate current share between units.
11.2~12.5V Auxiliary Voltage Output. Maximum load current is 0.5A.
This output has a built in O-Ring diode.
Not affected by the ENABLE signal or any other fault.
PMBus Address lines. Refer to the PMBus interface description RFE Instruction
Manual Section 5.1.3.
