The Multi Sentry series is ideal for protecting data centres and telecommunications systems, IT networks and critical systems in general, where the risks connected with poor energy supply can compromise the continuity of activities and services. The Multi Sentry series is available in 10-12-15-20 kVA models with threephase/ single-phase input and single-phase output, and 10-12-15-20 kVA models with three-phase input and output and on-line double conversion technology in accordance with VFI-SS-111 classification (as set out in standard IEC EN 62040-3). Multi Sentry is designed and built using state-of-the-art technology and components. It is controlled by a DSP (Digital Signal Processor)microprocessor, to provide maximum protection to the powered loads with no
impact on downstream systems, and optimised energy savings.
ZERO IMPACT SOURCE
MULTI SENTRY UPS are easy to install, especially on sites where there is limited power capacity available, a standby generator and potentially harmonic compatibility issues:
• 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
MULTI SENTRY also performs the role of a high specification filter, protecting its power supply sources (mains or generator) from any harmonics and reactive power generated by the loads it is powering.
BATTERY CARE SYSTEM
The MULTI SENTRY 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: MULTI SENTRY 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.
