UPS Sizing, UPS Sizing Guide, UPS System Sizing and Capacity Tips

UPS sizing and UPS system sizing is extremely important to get right before you even consider which UPS system is best for your application. There are various UPS sizing guides available online that can help you plan and cost your installation but when it comes down to it nothing can beat good, old fashioned experience, which you can only get from a detailed survey. Uninterruptible Power Supplies Ltd offers site surveys free of charge (see below for details). You can closely match your installation requirement by selecting UPS frame size, UPS module size and number of modules. The installation requirement itself depends on a number of factors, including:

• the maximum possible load
• the maximum likely load
• power factor
• the level of redundancy required
• Battery backup time autonomy may also be a factor

Remember that the more closely the UPS sizing and capacity matches its load, the more efficiently it will operate. Try our online tools to estimate an approximate configuration.
