Chloride unveiled its latest UPS which it said is expandable in 200KW modules delivering up to 9.6MW of power at up to 99% efficiency.

A single UPS can consist of up to six 200kW modules to achieve a 1.2MW rating. This can be expanded in parallel up to eight times to achieve 9.6MW.

The system runs in one of three modes: Maximum Power Control (VFI), Maximum Energy Saving (VFD), High Efficiency and Power Conditioning (VI). It monitors the quality of the power supply using an intelligent algorithm and automatically selects the most efficient operating mode to use only the energy required.

Rob Tanzer, technical support manager Chloride told Datacenterdynamics: ‘Each cubicle is a complete UPS. With a central input box this means an extra module can be added to achieve N+1 resiliency. And a single UPS means 200KVA giving 200KW. I don’t think anyone else is handling a unity power factor.’

Tanzer said the Trinergy removed any single point of failure issues as each module within a single cubicle is a rectifier or an invertor and is expandable up to six modules horizontally and up to eight ‘orthogonally’ or at right angles..

‘Each UPS share the load according to the number of modules and within each cubicle modules can be isolated and maintained. You can disconnect each module when needed. Concurrent maintainability means that single power modules can be isolated for safe maintenance, whilst the remaining modules continue to supply conditioned power to the load. Each module is designed with units which are easily withdrawable from the front for easy access and simplified maintenance,' he said. 





An additional function says Tanzer is the capability to correct voltage levels and harmonics and at the same time looking at the load thus acting as a true harmonic filter.

‘And if the load reduces then the modules may be switched off automatically. It actually measures the load. In a traditional UPS, in an N+N environment it is very often running at very light loads This means that it can provide up to 20% more output power than a similar UPS of the same kVA rating.'

An input power factor >0.99 and a Total Harmonic Distortion (THDi) of less than 3% reduces the generator power required to support the UPS system by as much as 25% over traditionally designed UPS systems, allowing further cost savings to be made.

In addition, a unique circular redundancy feature enables Trinergy to switch OFF excess UPS power capacity not being used to meet immediate load requirements.

By offering between 96% and 99% efficiency, Tanzer believes that this puts the Trinergy ahead of any other static UPS on the market. 'The industry is changing and customers are not going to accept 10% losses,' he said.
