Description
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.
