Automatic switching to a redundant power source

Scheduled switching on/off

Security functions for switched off system

Control System:

  • Isolated (500V) from input and output control interface: RS232 or RS422 (38400 bit/s)
  • Programmable output voltage switch on/off schedule
  • Watchdog timer switching the output voltage off in case of system hang up
  • Integrated temperature sensor
  • Integrated RTC with battery backup (for scheduled operation support)
  • System events signals routed to additional connector (input voltage below the limit, switching to power backup)
  • Switch system events signals to IRQ5, IRQ6, IRQ10, IRQ11 interrupts of PC/104 connector
  • Cold start at temperatures below –40°C an external heater can be used to preheat the system to the specified temperature. Output voltages are switched on when the temperature reaches –40°C
