Both uninterruptible power supplies support a load of 96 kW, which equates to 120kVA at a power factor of 0.8. The traditional or legacy system comprises two 120kVA UPS modules operating in a 120kVA N+N redundant configuration. The modular UPS system also provides redundancy in a N+1 configuration, using four 40kVA UPS modules to cover the load.
What factors affect the cost of uninterrupted power supply systems?
The cost of uninterrupted power supply (UPS) systems is influenced by various factors such as capacity, technology, battery backup runtime, redundancy features, and the reputation of the manufacturer. Additionally, considerations like installation, maintenance, and energy efficiency also contribute to the overall cost of ownership. 2.
How to manage the cost of ups implementation?
One of the most effective strategies for managing the cost of UPS implementation is right-sizing the system to match the specific needs of the business. Oversized UPS units not only incur higher upfront costs but also result in unnecessary expenditure on maintenance and energy consumption.
What are the advantages of a modular UPS system?
An added advantage for the modular UPS system is that it delivers nearly twice the power density – 206kVA/m2 compared with 111kVA/m2. To be complete and accurate, calculations of UPS power supply ownership costs should include provision for repair and maintenance.
