The data center's power, cooling and standby power supply must be able to adequately support current and future needs. Whether IT is building, refreshing or moving the data center, it is important to understand these requirements. Accurate estimates of facility requirements are a critical input to the project's final budget.

For example,If the power requirement is 1000W, then a 1500W rated unit with 12 battery blocks will deliver more runtime than a 3000W unit with 6 battery blocks. So in order to get the longest amount of runtime for your given application, the best solution is not necessarily to opt for the highest powered UPS within your budget, but to opt for an extended run UPS System that
