New compact UPSs with both performance and aesthetics
September 2006
Electrical Power & Protection
The series 9 uninterruptible power system from Meissner Uninterruptible Power Supplies, combines style and a small footprint of 305 x 702 mm with high performance.
Introduced earlier this year to South Africa, Powerware 9155 and 9355 UPSs have a strikingly modern appearance that sets them apart from the computer-grey masses of older equipment usually found in offices and server rooms. Instead, they have an elegant black casing and user-friendly, fully graphic, light blue backlit LCD display.
The 9155 is a single-phase model and the 9355 is a three-phase UPS, providing centralised power protection for industrial automation, server farms, networks, building systems, PC work stations, telecommunication systems and other mission-critical systems.
Such systems rely on a high level of power availability against all nine of the most common power disturbances - power failure, sag or surge, under- and over-voltage, switching transients, line noise, frequency variation, and harmonic distortion.
The new UPSs feature Hot Sync technology which enables precise load sharing, and allows parallel for redundancy and parallel for capacity configurations of UPS without a system level single-point-of-failure.
They have a high output power capability of 0,9 Pf specifically for compensated servers and communications devices, or more power for no extra cost. The standard battery configuration provides 10 to 15 minutes of backup time at 10 kVA computer load. This can be extended to well over an hour by adding extra battery packs.
Another of the product's features is an active IGBT rectifier for controlling the input power factor, without requiring an additional, expensive input filter to be 'mains friendly' or 'generator compatible'. This feature results in a THD factor of less than 5%.
The new range from Meissner also includes intelligent software and connectivity capabilities that enable monitoring and management of power systems from a desktop, from mobile devices, or through integration with network and building management systems.
Standard features include an advanced battery management (ABM) capability that actively controls the battery charging process, extending the lifespan of the battery system by up to 50% by charging batteries only when necessary, instead of the constant float charging method.
Meissner supplies the units complete with an external maintenance bypass facility that eliminates unnecessary downtime during UPS service and maintenance.
Other options include X-slot expansion cards for enhanced connectivity, ConnectUPS SNMP adapters, 12-pulse rectification, and isolation and voltage adaption transformers.
