The Delta RT-10K is the flagship of the Delta RT Series - a 10KVA (10000W) online double-conversion UPS built for enterprise-level power protection where equipment failure is not an option. With external batteries (240VDC) for scalable runtime, and the same true double-conversion protection, pure sine wave output, and zero transfer time as the rest of the range, it's engineered to keep mission-critical infrastructure online through any power event. This is the right choice for data centres, large server rooms, and industrial control environments. Suitable equipment includes multiple servers, large networking infrastructure, industrial control systems, medical equipment, data centres, and security monitoring centres. 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.
