  • UPS: What kind of UPS?

    Standby power supply - Ideally suited for an individual workstation, the standby power supply, or offline UPS, takes power straight from the wall outlet and passes it through.

When the main power fails, an inverter operating in standby mode converts the battery's DC power to AC to support the load for a limited time.
