Sentryum
The Sentryum (also marketed as Multi Sentryum or Multi Sentry depending on input/output configuration) is Riello’s tower-mount online double-conversion UPS at 10, 15, and 20 kVA — kVA equals kW so the unit power factor is 1. Three configurations are available: single-phase input/single-phase output (1:1, RPS Sentryum), three-phase input/single-phase output (3:1), and three-phase input/three-phase output (3:3). All configurations are parallelable and offered with internal or extended VRLA battery options.
The source page positions the range as a flagship for African deployments where utility supply (notably Eskom’s grid) is unreliable and load shedding is routine — efficiency is emphasised as the lever that reduces total cost of ownership over the unit’s lifespan. Note that the Standby URL slug sentrym is a shortened form; the manufacturer-side branding is Sentryum / Multi Sentryum.
