Modular & Three-Phase UPS Systems
Scale capacity in place with modular power modules, or protect a three-phase distribution board directly — sized to your facility, not a fixed catalogue unit.
Modular and Three-Phase, for Different Reasons
Modular UPS systems are built from hot-swappable power modules inside a shared frame, so capacity can be added as your load grows — and a failed module can be replaced without shutting the whole system down. That flexibility matters for facilities whose power demand is expected to change over time.
Three-phase UPS systems, separately, are sized for larger and three-phase-fed loads — industrial equipment, facility-wide distribution boards, or any installation where the incoming supply itself is three-phase rather than single-phase. We supply both, and in some cases the same modular platform, depending on your facility's actual load profile.
Modular & Three-Phase UPS Scope
- Modular UPS platforms with hot-swappable power modules
- Three-phase input/output UPS sized to your distribution board
- Capacity planning for facilities expecting load growth
- N+1 redundant configurations where the application calls for it
- Installation, integration and commissioning
Frequently Asked Questions
When does a modular UPS make more sense than a fixed-capacity unit?
Modular makes the most sense when your power demand is expected to grow, or when you can't tolerate downtime to swap a failed component — modules can be added or replaced without shutting the whole UPS down. For a stable, well-defined load, a fixed-capacity unit is often simpler and more cost-effective.
Do I need a three-phase UPS, or is single-phase enough?
That depends on your incoming supply and load size. If your facility's distribution board is fed three-phase, or the load itself is large enough to need balanced three-phase power, a three-phase UPS is the correct match. We confirm this during the load assessment rather than assuming based on facility size alone.

Maintenance and support after handover
Our work does not end at commissioning. We keep your systems running with a maintenance plan built around your site.
1, 2 or 3-year maintenance contracts
Planned preventive maintenance visits, inspection and test reports, and recommendations, on a contract length that suits your site.
Emergency visits
Emergency call-outs are part of the maintenance contract and are handled with priority according to the criticality of your site.
One team for every system
We maintain every system we supply and install, and we can take over the maintenance of existing systems on your site.
Visit frequency, emergency arrangements and spare parts are agreed with each client based on the site and the systems covered.
