The PREMIUM TOWER series uses on-line double conversion technology providing the highest level of reliability and protection for critical servers, network devices and voice/data applications. The PREMIUM range is fully microprocessor controlled providing high efficiency levels and greater configuration options.

Additional matching battery modules are available for extended runtimes.

The PREMIUM RACK series uses on-line double conversion technology providing the highest level of reliability and protection for critical servers, network devices and voice/data applications. The PREMIUM range is fully microprocessor controlled providing high efficiency levels and greater configuration options.

The entire range is based on a 2U design with additional 2U battery boxes available for extended runtimes.

The Starlet M UPS achieves the highest possible level of on-line double-conversion performance (VFI-SS-111) as defined within IEC EN 62040-3 and is designed to sit discreetly alongside traditional comms room equipment.

Zero impact source

The range is the ideal solution for installations where the power supply is limited, where the UPS is supported by a generator or where there are compatibility problems with loads that generate harmonic currents.

• Low Input current distortion < 3%
• High Input power factor 0.99
• Power walk-in and start-up delay functions

The Sirius P UPS uses a Power Factor Corrected IGBT Rectifier with Digital Signal Processors (DSP) to achieve the highest level of on-line double-conversion performance (VFI-SS-11) as defined within IEC EN 62040-3.

The range has a compact footprint (only 0.85m2 for a 250kVA UPS) with an enclosure design that enables maintenance access from the front and “back to wall” installation; combine this a with an integral output transformer providing Galvanic Isolation through the inverter, make this the versatile choice for modern data centres and industrial loads.

Zero impact source

The range is the ideal solution for installations where the power supply is limited, where the UPS is supported by a generator or where there are compatibility problems with loads that generate harmonic currents.

• Low Input current distortion < 3%
• High Input power factor 0.99
• Power walk-in and start-up delay functions
• Optional Generator card enabling inhibit of battery recharge
• Optional UGS and PSJ systems for Synchronisation and Dual Bus systems

The MultiGuard is a scalable three phase UPS providing online double conversion technology that is designed to sit discreetly alongside traditional comms room equipment.

The ‘modular’ solution provides scalability for continued resilience or future capacity when loads increase without the need to find more valuable floor space within your comms room. Based around a 15kVA module which can be supplied in either 30kVA, 60kVA or 120kVA cabinet solutions providing the flexibility to suit both small and large applications

Our Partnership with ELCOS Generators in Italy enables competitive proposals with market leading availability.

• Ratings from 37kVA to 3.3mVA
• Standby and prime rated applications
• Bespoke soundproofing for reduced noise
• Extended integral and external fuel tanks
• Volvo, Cummins, Perkins, Iveco & Mitsubishi Engines
• Manufactured in Italy to ISO9001:2008
