The best solution will be the one that best meets the requirements of the end system.įor further information on MEAN WELL buffer modules, please contact ADM. Of course, a UPS and a buffer module each have their own advantages and disadvantages. When reliability, size, noise, cost, operating temperature, or maintenance aspects are considered, a MEAN WELL buffer module could be more advantageous, and is a smart choice for most users. When the AC fails, the built-in relay is activated, giving an alarm so that preventative action can be taken, whilst the buffer module is supplying the power. MEAN WELL buffer modules also feature a relay output. The overall MTBF (meantime between failure) rate is also slightly higher than that of a UPS. This means it is more compact and its reliability is relatively higher. If the equipment being powered requires a larger load, or longer buffer time, multiple buffer modules can be used in parallel as shown below:Ĭompared with a UPS, a MEAN WELL buffer module has a simpler design. Video of DBUF20/40 20A/40A DIN Rail Buffer Modules Function Illustration These are an ideal low cost solution for when you need a short term UPS system. To mitigate these shortcomings, MEAN WELL has introduced buffer modules as an alternative. The large size of a UPS, its noise, and required maintenance schedule can be an inconvenience. Some batteries need to be fan cooled, which can be noisy. Moving parts are also known to increase the likely failure rate of a device. The operating temperature of batteries is typically around 0℃~ 40℃. When the AC does fail, the UPS needs about 2 to 10 milliseconds to switch over to battery output. UPS power supplies are commonly used in areas with frequent power failure, or to power critical infrastructure. When the grid’s AC power is available, the UPS charges itself. If the grid power fails, the UPS supplies electrical energy to the load from its battery. One of the key requirements for a data center is power stability. Typically, an uninterruptable power supply (UPS) is used to ensure system stability.Ī UPS is composed of battery packs, inverters and control circuits, with one end connected to the power grid and the other end connected to the load. The growing demand for services such as online conferencing means that larger data centers and cloud storage capacity is needed. This means that there is evermore voice, video, and email data being transmitted via electronic devices. The other functions bring huge additional value to organisations trying to achieve net-zero, reduce electricity bills and gain greater control of their energy usage.Working from home and remote learning are becoming more commonplace. To date it is the only system that the NHS has approved for use in this way. Uniquely for a UPS that is connected Behind-the-Meter, a Powerstar system can be used for other functions while it is in standby, awaiting a power disruption. A Powerstar system consumes about 95% less electricity, saving carbon emissions and cost. For example, a 1MW UPS system could consume around £200,000 worth of electricity every year. If we use our 1500VA UPS, it provides us with approximately 192VAh (the provided specifications state that the unit houses 2 x 12V/8Ah batteries). Typically, large UPS systems consume significant amounts of energy to remain powered up and on standby for a possible power disruption. For example, a manufacturing site will need all of its production lines, machine tools, robots and PLCs to remain live, as well as its compressor and production management software. This is essential where there are multiple critical electrical systems, or where they are interacting with each other. This means that no equipment will shut down, reset or fail in the event of a disruption. Ranging from around 300kW to 10MW, Powerstar UPS solutions are large enough to support an entire commercial or industrial site. For example, a company’s computer server will typically have a UPS connected to it, so that in the event of a power failure it does not switch off. The majority of UPS system are small and protect a specific piece of equipment. We design and manufacture a very specific kind of UPS which has three significant benefits over others: 1. UPS systems come in many shapes and sizes.
