The customer required a fully redundant solution for their updated server room that would last at least 2 hours from a mains outage and be provided by a professional company which could supply, install and maintain the complete solution from distribution board input to the PDU’s the racks fed by the new UPS protected distribution board.


Critical Power Supplies proposed an APC 20KVA rack mounted N+N solution in comprehensive fixed price turnkey package which delivered a maintained solution which provided all the features the customer require within the budget available. This gave the IT department complete redundancy in case of failure at any point and allowed batteries to be replaced in years to come without having to switch off the load by utilizing the bypass system and APC’s hot swap battery technology. Combing the APC UPS efficiency and reliability with our ability to deliver a turnkey installation with comprehensive project management allowed us to deliver costs savings though a quick-roll out and integration, that traditional procurement methods would not have been able to manage.


The installation was completed in 3 days and consisted of 2 feeds into two new bypass switches, two new DB’s and then each rack had 2 feeds, one from each UPS. The IT dept now have a fully redundant 3 hour runtime system. The Installation is designed to the latest standards in critical power and electrical circuits. The project was delivered on time and on budget.
