Description
Positive output voltage
+V Signal
-V Signal
Negative output voltage.
Differential digital signal for parallel control. (Note.1)
The unit can turn the output on and off by electrical signal or dry contact between ON/OFF and +5V-AUX. (Note.2)
Short (4.5 ~ 5.5V) : Power ON ; Open (0 ~ 0.5V) : Power OFF ; The maximum input voltage is 5.5V.
Not use.
Serial Data used in the PMBus interface. (Note.2)
Serial Clock used in the PMBus interface. (Note.2)
Low (0 ~ 0.5V) : When the input voltage is 87Vrms. ≧
High (4.5 ~ 5.5V) : When the input voltage in 75Vrms . The maximum sourcing current is 10mA and only for output. (Note.2)≦
High (4.5 ~ 5.5V) : When the Vout 80% 5%.≦ ±
Low (0 ~ 0.5V) : When Vout 80% 5%. The maximum sourcing current is 10mA and only for output. (Note.2)≧ ±
High : When the internal fan fail. (4.5 ~ 5.5V)
Low : When the internal fan is normal. (0 ~ 0.5V) The maximum sourcing current is 10mA and only for output(Note.2)
Auxiliary voltage output GND. The signal return is isolated from the output terminals (+V & -V).
AC Ground connection.
AC Line connection.
AC Neutral connection.
Connection for output voltage trimming. The voltage can be trimmed within its defined range. (Note.1)
Positive sensing. The +S signal should be connected to the positive terminal of the load. The +S and -S leads should be
Negative sensing. The -S signal should be connected to the negative terminal of the load. The -S and +S leads should be
High : When the internal temperature (TSW1 or TSW2 open) exceeds the limit of temperature alarm.(4.5 ~ 5.5V)
Low : When the internal temperature (TSW1 or TSW2 short) under the limit temperature. (0 ~ 0.5V) The maximum sourcing
current is 10mA and only for output(Note.2)
Auxiliary voltage output, 4.5~5.5V, referenced to GND-AUX (pin 31). The maximum load current is 0.3A. This output has the
Auxiliary voltage output, 10.8~13.2V, referenced to GND-AUX (pin 31). The maximum load current is 0.8A. This output has
PMBus interface address lines. (Note.1)
