What is a UPS Multi-Power?
The RIELLO UPS Multi-Power is a unique modular UPS system involving three-phase uninterruptible power supply in on-line double-conversion typography. Available in 25kW or 42kW power modules, the specially-designed components and transformer-less technologies of the UPS Multi-Power allow it to offer efficiency levels of 96%.
Development of the modular UPS
The uninterruptible power supply (UPS) was originally developed to provide a continuous supply of clean power to critical machinery. While the underlying functionality of the UPS device remains the same, the UPS system design has had to evolve to keep up with the technological developments within the electronics’ industry. This has prompted an upgrade from the transformer-based UPS (the standalone, monolithic UPS system) to the transformer-less modular UPS system, such as the UPS Multi-Power. These consist of smaller units which are used in parallel, providing safer, more reliable power.
The UPS Multi-Power system is designed primarily to protect:
- Critical, high-density computer and IT environments
- Data centres
- Critical loads
UPS Multi-Power Electricity Savings
As previously mentioned, South Africa is experiencing national shortages in electrical supply which has prompted the re-introduction of load-shedding to ensure the national grid doesn’t fail completely. The result of this shortage is the increased demand for UPS systems and the increase in electrical bills countrywide.
Fortunately, the modular UPS systems are hugely beneficial in terms of cutting your electricity bill. The reason for this is that the RIELLO Multi-Power UPS system’s efficiency increases with loading, with modular units running at 96% efficiency. This is a big improvement on the 91% efficiency of the transformer-based standalone units. By improving efficiency, an organisation reduces direct energy requirements while also benefiting from savings related to cooling costs for data centres.
By replacing your static UPS to a more efficient, power-packed modular Multi-Power system, organisations are able to cut carbon emissions and cooling costs by around 72% a year. The cost-savings related to electricity for bigger operations can average up to R30 000 a year.
Consider the load factor for UPS energy efficiency
As mentioned earlier, the modular UPS efficiency is determined by its load factor which is how much of its power capacity is being used. When a UPS is operating at 100% capacity, it will attain its optimum efficiency raging, however, if it is operating at a lower capacity, there is more energy loss. When the load is below 50% of the UPS capacity, energy efficiency declines, with a substantial drop after 30% capacity.
Additional benefits of a UPS Multi-Power
Beyond energy efficiency, the UPS Multi-Power systems offer significant benefits to businesses, including:
- Scalability: the RIELLO Multi-Power UPS system provides a pay-as-you-grow incentive for businesses which optimises the initial investment.
- Space-saving: the RIELLO Multi-Power UPS system reduces the risk of wasteful oversizing at installation.
- Easy maintenance: the RIELLO Multi-Power UPS system consists of modules which are ‘hot-swappable’, so preventive UPS maintenance can be undertaken without the system going offline.
- Reliability: organisations can be assured of uninterrupted clean power to protect critical loads at all times.
As with most technologically-advanced equipment, the initial cost is somewhat higher than previous models, but the savings on electricity through reduced operating costs, savings related to maintenance, enhanced reliability and efficiency ensure the initial cost is absorbed relatively quickly. UPS systems are also available with ‘eco-mode’ which will further reduce energy consumption.
