Complete range 60-200 kVA
High efficiency up to 96.5%
Flexibility of use
Exceptional performance and efficiency.
Multi Sentry is a state-of-the-art uninterruptible power supply, achieving the highest possible level of on-line double-conversion performance (VFI-SS-111) as defined within IEC EN 62040-3.
The UPS has been designed to protect critical information and telecommunications systems, networks, services and processes whose operation could be disrupted by poor power quality and/or breaks in their mains power supply.
The sizes available include: 60-80-100-120-160-200 kVA all with a three-phase input and utput.
The Multi Sentry UPS is one of the most efficient UPS available with a minimal impact on its environment and power sources.
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:
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:
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.
Multi Sentry can be used for a wide range of applications, thanks to its configuration options, flexibility, accessories and performance levels:
Multi Sentry has a large front panel graphic display providing information including: real-time measurements, operating status and alarms conditions - in eight different languages
LOW MANAGEMENT COST
The Multi Sentry design provides exceptional performance and efficiency levels, within a very compact footprint and overall case design:
