• Low input current distortion - less than 3% • High input power factor 0.99 • Power walk-in function to achieve progressive rectifier start-up • Delayed start-up on mains power supply return
The DS 3 LEVEL Battery Care System optimises battery performance, to help extend their working life and ensure that the UPS can deliver its full-rated back-up time when called upon in an emergency. Battery recharge: DS 3 LEVEL is designed to work with VRLA AGM and GEL lead-acid batteries including open-vented types, in addition to Ni-Cads. Specific management features include:
• One-level recharge to meet the requirements of the most common VRLA AGM batteries • Two voltage level recharge meeting the IU characteristic • Restricted charging to reduce electrolyte consumption and extend the life of VRLA batteries Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient
Battery test: to detect performance degradation and predict battery failure. Deep discharge protection: to prevent the batteries being discharged below a level from which they cannot be recovered (especially when discharged over long periods with very low loads). Low AC ripple current: from a high-frequency battery charger, to ensure the batteries are not subjected to this damaging element commonly experienced with some other UPS and power supply designs. Wide input voltage range: from a rectifier that can work down to less than 40% of its nominal supply rating (at half load), removing the need to discharge the batteries
DS 3 LEVEL can be used for a wide range of applications, thanks to its configuration options, flexibility, accessories and performance levels: • Suitable for powering capacitive loads, for example Blade servers - without any reduction in active power, from 0.9 leading to 0.9 lagging • Modes of operation include: On-Line, Eco, Smart-Active and Stand-By/Off • Frequency conversion mode • Power Share connections for priority-based load shedding when the mains power supply has failed • Cold-start facility to switch the UPS on even without a mains power supply present • Extensive back-up time options using battery extension cabinets • Optional battery cabinet temperature sensor to assist the temperature compensating charger • Optional battery chargers to optimize recharge times • Optional dual input supplies • Optional isolation transformers for Galvanic isolation and neutral connectivity
The DS 3 LEVEL design provides exceptional performance and efficiency levels, within a very compact footprint and overall case design: • Lowest footprint in its category - 0.26m² for the 20kVA DS 3 LEVEL with internal batteries. • High efficiency up to 94% - saving up to 35% in dissipated energy in one year compared to a more traditional UPS (91%) resulting in a faster payback period of four years. • High output power factor which at 0.9pF provides up to 15% more active power compared to a more traditionally sized UPS - providing greater system expansion margin for further load increases.
