Battery backup times

To determine backup times, the load power needs to be a known value. If the load and time requirements need an external battery added, it is indicated with the “1+1” designation.

Replacement batteries are the commonly available Panasonic UP-VW1220P1 modules. Two are required for the UPS, and two are required for the external battery module.

Signaling and communications

The TRIO AC-UPS is capable of providing diagnostic information in regards to the condition of the battery backup system. As shown in figure 5, there are terminals for multiple outputs and control inputs.

Using these terminals allows for a forced shutdown/startup from the battery bank, indication of the battery readiness, indication of battery mode, and alarm conditions.

LEDs provide localized indication of the present condition of the UPS including:

  • AC input condition
  • Battery operation
  • Battery failure
  • Battery charging
  • Service mode
  • Overload in battery mode
  • Many others
