Outstanding performance and efficiency

 

Multi Sentry (MST) is a transformer-free UPS designed to handle capacitive loads without any reduction in active power, making it ideal for data centres or mission-critical telecommunications and IT networks.  

 

Space-Saving Design

MST enjoys one of the most compact footprints in its category, making it a winning choice if you’ve got restricted space or under commercial pressure to optimise your floor space. Delivers high efficiency of 96.5% and near unity power factor.

Scalable Solution

Parallel a maximum of 8 MSTs together to scale up your power or build in redundancy (N+1). Parallel configurations run on a closed-loop system, guaranteeing continuous operation even if there’s an interruption to the connection cable.

Technical specifications of the model

A transformerless UPS offering you high efficiency in a compact footprint, the Multi Sentry is a superb solution for sites that have limited power, loads that generate harmonic currents, or where the UPS is supported with a generator.

Designed to power capacitive loads like blade servers without any reduction in active power. Range of battery cabinet sizes depending on your runtime requirements.

 

Because 1 Size Doesn’t Fit All…

Multi Sentry is available in 160 and 200 kVA power ratings to suit your specific power requirements.

It’s a proven solution for protecting everything from small telecoms and ICT networks through to sizeable data centres.

 

Zero Impact On Power Source

Whether the input is the mains or a generator, the MST has zero impact. It ensures an input power factor (pf) of 0.99 and low current distortion (< 2.5%), while it deploys a power walk-in function that ensures progressive rectifier start-up.

The MST also offers filtering and power factor correction in the network upstream of the UPS.

 

Exceptional Efficiency

Developed using advanced transformerless technologies including a 3-level inverter and fully-controlled IGBT rectifier, the MST delivers you high efficiency of up to 96.5%, with a flat efficiency curve that minimises waste even at partial loads.

 

Scalable Solution

Parallel a maximum of 8 MSTs together to scale up your power or build in redundancy (N+1).

Parallel configurations run on a closed-loop system, guaranteeing continuous operation even if there’s an interruption to the connection cable.

 

Compact Footprint

The MST enjoys one of the most compact footprints in its category, meaning it’s an ideal choice if you’ve got restricted space or under commercial pressure to optimise your floor space.
