Overview
The highest-capacity model in the Fortress range: three-phase online protection at data-center scale.
The Fortress 3P/3P 120KVA is a true online UPS with three-phase input and output, a built-in output isolation transformer, and pluggable power modules that can be serviced from the front. It combines unity output power factor and active power factor correction on all phases with parallel redundancy capability, so you can scale or add fault tolerance as your facility grows, all monitored through a 7" touch LCD.
Why the Fortress 120KVA
- Built-in output isolation transformer: full galvanic isolation between the UPS and your load for the most demanding environments.
- Pluggable power module design with front access: faster servicing and reduced mean time to repair (MTTR).
- Parallel redundancy capability: add units for extra capacity or fault tolerance, with a common battery.
- Output power factor 1: more real power (kW) from every kVA, supporting more load without oversizing.
- Active power factor correction on all phases: efficient, balanced mains draw with lower stress on cabling and generators.
- Dual-mains inputs: separate mains and bypass supplies for greater resilience.
- Four built-in switches: mains input, bypass input, output, and maintenance bypass for safe, uninterrupted servicing.
- Power walk-in function: gradually ramps load back onto the mains after an outage, protecting generator-backed sites from sudden surges.
- Flexible battery configuration and adjustable charging current: match the UPS to your battery bank type and capacity.
- 7" touch LCD screen: comprehensive status, load, and battery information on a clear display.
- 50Hz/60Hz frequency converter mode: supply equipment designed for a different frequency from your local grid.
- Generator compatible and emergency power off (EPO): reliable on generator sites, with immediate shutdown for safety situations.
Who it's for
Data centers, large industrial plants, hospitals, and critical infrastructure that need maximum single-unit three-phase capacity with isolation and redundancy options.
