Chapter 1 Introduction
The PowerWalker VFI 3/3 Series VFI 20000-80000TAP 3/3 BE/BI uninterruptible power supply (UPS) is a
true online, continuous-duty, transformer-free, double-conversion, solid-state, three-phase system,
providing conditioned and uninterruptible AC power to protect the customer's load from power failures.
The PowerWalker VFI 3/3 Series VFI 20000-80000TAP 3/3 BE/BI online power protection system is used to
prevent loss of valuable electronic information, minimise equipment downtime, and minimise the adverse
effect on production equipment due to unexpected power problems.
The PowerWalker VFI 3/3 Series VFI 20000-80000TAP 3/3 BE/BI UPS continually monitors incoming
electrical power and removes the surges, spikes, sags, and other irregularities that are inherent in
commercial utility power. Working with a building's electrical system, the UPS system supplies clean,
consistent power that sensitive electronic equipment requires for reliable operation. During brownouts,
blackouts, and other power interruptions, batteries provide emergency power to safeguard operation.
The UPS is housed in a single free-standing cabinet, with safety shields behind the door for hazardous voltage
protection.
This manual is for PowerWalker VFI 3/3 series UPS, refer to Table 9-1 for product models.
