Overview

This highly acclaimed modular UPS delivers the highest levels of critical load availability, total flexibility, energy efficiency and the lowest total cost of ownership (TCO) in the industry.

Maximum availability - Kohler PW 9000DPA provides class leading ‘Six nines’ (99.9999%) availability by uniquely combining the benefits of decentralised parallel architecture (DPA™), parallel redundancy and ‘hot-swap’ modularity to ensure 24/7 power availability. 

Total flexibility - Kohler PW 9000DPA’s true ‘hot-swap’ modularity enables power to be added in cost-effective incremental steps as power requirements grow, thus right-sizing the UPS to the actual critical load and without increasing the footprint.  Additionally, the ability to ‘hot-swap’ modules online significantly reduces the system’s mean time to repair (MTTR) and simplifies system power upgrades.

Key Benefits

• Paralleable up to 1MVA N+1
• ‘Six nines’ (99.9999%) availability
• Up to 250kVA (200kVA N+1) is a single frame
• Decentralised Parallel Architecture (DPA™) assures exceptional reliability, availability and maximum uptime through critical component and circuitry duplication
• ‘Hot-Swap’ modularity provides total flexibility ensuring the UPS can be ‘rightsized’ to the critical load at initial installation, reducing initial costs, optimising operating efficiency and reducing the total cost of ownership.   
• Quick and simple power upgrade or repair by ‘Hot Swapping’ modules while the UPS is online maximises availability and simplifies system upgrades
• High operating efficiency across a wide load range (95% to 96% efficiency from 25% partial load to 100% full load) reduces system running costs and site air conditioning costs, reducing system carbon footprint.
• Small footprint – only 0.43m² at 250kVA (200kVA N+1) delivering a power density of up to 342kW/m^{2 –}allowing substantial and valuable space savings even at the highest power ratings
• Near unity power factor at partial and full loads (PF>0.99 @ 100% load)
• Low input harmonic distortion (THDi<3%)
• Blade server friendly – provides fully rated output power to power factors between 0.9 leading and 0.8 lagging
• Transformerless technology
• Easy front access for operation and maintenance
