  • Page 67: Understanding Ups Operation

    Chapter 5 Understanding UPS Operation UPS System Overview The VFI 20000-80000TAP 3/3 BE/BI/BX UPS is a continuous-duty, solid-state, three-phase, true online system that provides conditioned and uninterruptible AC power to the UPS system's output and critical load. The basic system consists of a rectifier, battery converter, inverter, monitoring/operation control panel, integrated communication server, and digital signal processor (DSP) logic.

  • Page 68: Single Ups

    Single UPS A single UPS operates independently to support an applied load from the inverter, providing conditioned and uninterruptible AC power to the critical load from the output of the module. During an outage, the inverter continues to operate, supporting power to the load from the battery supply. If the unit requires service, applied loads are transferred to the internal bypass either automatically or manually.

    5.2.4 Bypass Mode CAUTION The critical load is not protected from voltage or frequency fluctuations or power outages while the UPS is in Bypass mode. The UPS automatically switches to Bypass mode if it detects an overload, load fault, or internal failure. The UPS can also be transferred from Normal mode to Bypass mode manually.

  • Page 71: Battery Mode

    5.2.5 Battery Mode The UPS automatically transfers to Battery mode if a utility power outage occurs, or if the utility power does not conform to specified parameters. In Battery mode, the battery provides emergency DC power that the inverter converts to AC power. Figure 5-4 shows the path of electrical power through the UPS system when operating in Battery mode.
