Overview
Sentryum is our third generation transformerless ONLINE UPS designed to maximise availability, efficiency and performance in small data centres and similar critical applications. Delivers 96.6% efficiency and unity power (pf 1).
Active (ACT) - 2 battery strings in 0.35m2² footprint
Enhanced Performance
Highlights
- Sentryum builds on previous transformerless series such as Multi Sentry (MST) with an optimised card layout that reduces the number of components, cables, and interconnections. This means your UPS needs less space and is far more cost-effective to maintain.
- Choice of 3 cabinet sizes (Compact, Active, Xtend) to maximise battery runtime
- 96.6% operating efficiency (ONLINE mode) reduces energy waste
- High overload and short circuit capacity guarantees availability
- Designed to handle non-linear loads so ideal for blade servers
- Reduces harmonic voltage distortion (<1% at resistive load and < 1.5% at non-linear load)
- Parallel up to 8 UPS for extra capacity or redundancy
- Large 5-inch colour touchscreen display shows UPS status, load, and battery level
- LED indicator automatically changes colour depending on the UPS's status
