Sentinel Dual SDU
Sentinel Dual is the best solution for powering mission critical applications and electro-medical devices requiring maximum power reliability.
The Sentinel Dual range is available in 4 kVA and 5-6-8-10 kVA/kW models with ON LINE double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of voltage, form and frequency.
Reduce your power consumption using ECO and SMART ACTIVE modes. Prioritise your most critical loads with EnergyShare sockets that enable easy load-shedding. Load-controlled fans minimise noise disruption (<48 dBA).


Sentinel Tower
Sentinel Tower is the ideal solution for protecting mission critical systems such as safety devices, telecommunications equipment but also IT systems to ensure maximum power reliability.
Sentinel Tower is designed and built using state-of-the-art technology and components to provide maximum protection to the powered loads with no impact on downstream systems and optimised energy savings.
The series includes 5-6 kVA single/singlephase and 8-10 kVA single/three-phase input single-phase output models with ON LINE double conversion technology (VFI):
the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of form and frequency. Input and output filters provide significant further immunity from mains disturbances and lightning strikes.
Sentryum
Our third generation of transformerless ON LINE UPS systems, the 10-40 kVA Sentryum rewrites the concept of flexible power by offering a choice of three compact cabinet sizes to suit the needs of any small data centre or mission-critical application.
Enhanced overload and short circuit capacity guarantee maximum availability. Incorporating a 5-inch colour touchscreen display and intuitive LED status indicator that automatically changes colour based on the UPS’s current operating state.


Multi Sentry
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 output.
