Backup Power Systems for Mission Critical Applications

10 Jan 2024
Since year 2000, APECUS has been in the business of providing Power Backup Systems to data centres, healthcare industries and government sectors as well.

The customer is looking to replace 14 sets of existing Backup Power Systems island wide for one of the ministries in Singapore. The existing systems had been in operation for about 7 to 10 years, 24 hours 7 days a week. As Power Backup Systems supports an important infrastructure, it is vitally important for the system to be reliable and efficient. After a thorough consideration and evaluation on the condition of the existing Uninterruptible Power Supplies (UPS), a technical refresh is being called for
The Challenges:
The footprints of all the existing Backup Power Systems are fixed and there are little rooms for changes. This limitation posed a great challenge in the recommendation of UPS models and their re-cabling works from the incoming supply to the distribution boxes as well as the outgoing supply and their distribution boxes. The difficulty is also heightened by the limited downtime caused by the essential activation of supporting loads.
Our Approach:
Upon reviewing our product catalog, the project team suggests implementing a modular UPS featuring 20kVA power modules for this deployment. This approach enables the team to optimize efficiency based on the available incoming power and space constraints.

To address the challenge of limited downtime, the project team devised a strategy for scheduling and installation. They planned to install and activate the new UPS units with partial battery connections to ensure immediate power backup in the event of a power outage, thereby reducing downtime to just one day instead of five. Once the UPS is operational, the team proceeds to configure the remaining batteries that contribute to the required backup time.
The Result:
Drawing upon the expertise of our skilled core team and adept project management, we have the capability to wrap up and deliver the installations ahead of the planned schedule, all the while upholding top-notch quality standards without any compromise.
