The Delta RT-6K is a 6KVA (6000W) online double-conversion UPS built for high-demand commercial and industrial environments running multiple critical systems at once. With external batteries (192VDC), it supports scalable runtime through additional battery packs, and delivers the same true double-conversion protection, pure sine wave output, and zero transfer time found across the Delta RT Series. It's suited to environments where several servers, security systems, or medical devices need to stay online no matter what happens on the grid. Suitable equipment includes multiple servers, network cabinets, security control rooms, medical equipment, small data centres, and telecommunications systems. On light load, expect up to 1 hour of backup on 7Ah batteries or 1+ hour on 9Ah batteries (extendable with external battery packs). Additional features include LCD display with intelligent monitoring, overload and short circuit protection, and high efficiency operation. Price excludes VAT.
