Modular UPS Systems

Modular UPS Systems

Modular UPS allow you to right-size your uninterruptible power supplies for your current load and resilient level requirements and prepare for future expansion at a later date.

The Modular UPS sytems are high efficiency systems achieving 96% or greater efficiency. They can also be run in Eco Mode and have energy saving characteristics including module hibernation (at low load) and battery charger disconnect. Compared to traditional Mono-block uninterruptible power supplies, the other advantages for modular systems include: a compact footprint and floor space saving for comms rooms and datacentre environments, right-sized battery packs, reduced service times and maintenance contract prices.

When planning a Modular UPS the first step is to select a frame size to meet your current and expansion needs and ensure that surrounding electrical switchgear is suitably sized. The frame size will incorporate a suitably sized static switch and maintenance bypass arrangement and allow future UPS modules to be added a later date. The smallest UPS modular system typically runs from 25kVA/20kW (Unity Power Factor rated) and can be extended to 1MVA total capacity or in an N+X configuration. For each of the Modular UPS systems we offer we have provided sizing tables at the end of this page.
