Overview

The RED3310S-E is the 10 kVA standard (S) model in the RED3300-E Series of three-phase in / three-phase out, true double-conversion online UPS, rated at 380/400/415 Vac for the UK and other IEC markets.

The standard build carries its batteries internally for short autonomy, in a 250 mm-wide tower cabinet.

Battery autonomy, string configuration and battery cabinet selection are sized per project — contact us with your load and runtime requirements. Figures are typical values for reference only; specifications are subject to change without prior notice.
