Fail-safe engineering ensures that any malfunction of a power supply or even a microprocessor should not threaten the load.
AEC UK's T7 UPS system provides multilevel protection against internal failure, making it suitable for critical control applications.
Available from 100 to 650kVA, the three-phase system uses double-conversion online technology to provide clean and reliable power to sensitive IT and telecommunications equipment, improving productivity and lowering power costs.
The T7 comes with a digital IGBT rectifier, ensuring low input THD with a 0.99 power factor.
This ensures higher efficiency, generator compatibility and a cleaner supply without the need for expensive filtering or a rectifier upgrade.
The T7 can be configured to operate in parallel, offering an N+1 configuration.
The parallel control system tightly manages both active and reactive loads, allowing for intelligent load/current sharing between each phase.
When running in parallel, conventional UPS systems work on a master/slave principle, which means that, should the master UPS fail, the whole system fails.
With the T7, each system is connected to the other via a robust CANbus connection and is supplied with its own parallel monitoring system, removing a single point of failure.
The T7 series incorporates Tri Core technology, which includes both DSP and microprocessor applications.
This fail-safe engineering ensures that any malfunction of a power supply or even a microprocessor should not threaten the load.
All crucial components, modules and systems are constantly monitored, allowing predictive maintenance.
DSP, IGBT and Tri Core technology allow the T7 to offer AC/AC efficiency of 93%, which is typically around 8% better than conventional UPS and provides savings of 2.8kW per on hour on a 40kVA installation.
The efficiency of the T7 reduces the heat produced, allowing the air conditioning system to be down-rated.
Intelligent cooling allows the T7 series to be positioned against back or side walls.
Air is drawn through the front and expelled through the top.
All components can be easily accessed from the front for maintenance.
The system is suitable for industrial applications including railway, petrochemical mining and process control.
The T7 conforms to relevant electrical safety standards, carries the CE mark and is supported by AEC UK.
