Page 6: Description
PV- 5127: Power supply module with UPS Description The Micronix PV-5127 is a high efficiency PC/104 power supply for embedded, vehicular and automotive systems applications. It will withstand extended temperatures and the shock and vibration of mobile equipment. Micronix PV-5127 has an input supply range of 18-35V (PV- 5127A: 10-35V), which is convenient for automotive and low-voltage applications. - Page 7 Users Manual & Installation Guide PV- 5127: Power supply module with UPS The mains supply is continuously monitored. There is hysteresis on the mains monitor so that a mains failure is reported when the mains voltage drops below 16.5V, and mains is reported OK when the voltage rises above 17.5V.

Users Manual & Installation Guide PV- 5127: Power supply module with UPS ATX and Softoff state machines The PV-5127 provides several ways to turn on/off power. ATX compatible CPUs can turn themselves on and off using PS_ON, and UPS monitoring software on CPUs without PS_ON can turn off using either a RS232 handshake signal or a software command through the PC/104 bus. -

SOFT_TEMPBAD. SOFT_ON and SOFT_DELAY are the “on” states, i.e. only in these states can the 5V+12V be turned on. SOFT_OFF and SOFT_TEMPBAD are the “off” states, where the 5V+12V is guaranteed to be off.
