What an 80kVA UPS is for
An 80kVA UPS (80 kW at unity pf) protects medium data centres, industrial plant and large commercial installations. Three-phase supply is standard and modular N+1 architecture is the norm. 80kVA is also the top of the Legrand TriMOD HE single-cabinet range.
Modular N+1 at 80kVA
A modular frame — Riello Multi Power or Legrand TriMOD HE (up to 80kVA) — lets you build 80kVA from hot-swappable modules with one spare for N+1 redundancy. Modules can be added or serviced without dropping the load. Sentryum S3T also covers 80kVA in a monolithic cabinet up to 120kVA.
Efficiency and Energy Saving
Modern 80kVA modular UPS reach 96–98% efficiency online. Energy Saving mode shuts down redundant modules at low load, so an 80kVA system running below capacity does not waste energy. This protects PUE and lowers operating cost.
Runtime, redundancy and models
External battery cabinets or lithium banks extend runtime to an hour or more. Build N+1 with a modular frame or parallel monolithic units. Strong 80kVA options include Riello Multi Power, Sentryum S3T and Legrand TriMOD HE.
Frequently asked questions
Is an 80kVA UPS three-phase?
Yes, three-phase is standard at 80kVA.
Can I build N+1 at 80kVA?
Yes. A modular frame (Multi Power, TriMOD HE up to 80kVA) gives hot-swap modules and N+1 redundancy with downtime-free maintenance.
How efficient is an 80kVA modular UPS?
96–98% online, with Energy Saving mode improving efficiency at low load by shutting down redundant modules.
What runtime does an 80kVA UPS give?
Minutes on internal batteries; external cabinets or lithium banks extend this to an hour or more.
