  • Modified the UPS input waveform detection scheme sub routine. This repaired a unique case in the firmware that delayed the UPS transfer time to battery operation when utility dropped down from 100 volts to 60 volts under certain conditions.
  • Modified the Advanced Voltage Regulation (AVR) detection scheme by reducing the number of cycles required to detect an out of tolerance voltage condition. This repaired an issue in the firmware that allowed the UPS to stay in its current AVR mode and not perform a buck or boost cycle quick enough.  This issue resulted in the output voltage falling outside of the output voltage specification when utility dropped down from 100 volts to 60 volts under certain conditions.
