An uninterruptible power supply, commonly known as UPS Power Supply is easy to install a device that is designed to provide power to your computers, servers, server rooms and data centres in case of main energy failure, electrical surge or unexpected energy cut off. These devices contain a battery that guarantees power to your computer system for a certain period of time, creating an extended run long enough to shutdown software or for saving the current task and shutting off the computer.
What Types of UPS Uninterruptible Power Supplies Are There?
There are several types of UPS system solutions available:
- Online UPS - A system of supplying power by converting AC input (utility power) to DC and reconverting it to stable AC by the inverter while constantly charging the batteries. Supplies power without momentary power breaks in the event of a power outage.
- Standby UPS - A system where, normally AC input (utility power) is output as is to connected devices and when a power outage or abnormal voltage is detected, the inverter starts feeding using power from the batteries. In the event of a power outage, a few milliseconds of momentary break occur in AC output.
- Parallel processing UPS - While power from AC input (utility power) is supplied, the bidirectional inverter connected in parallel corrects voltage and absorbs noise. Because this is the online inverter (parallel) system, it has both high efficiency and high reliability.
- Hybrid UPS - This system consists of three modes: double conversion mode, economy mode, and active filter mode. The UPS automatically selects the power feeding mode to best suit the power situation and load conditions. It is possible to shift between the respective modes with no momentary break in output voltage. Double conversion mode is selected when the power situation is poor and economy mode is selected when the power situation is good.
How Do Uninterruptible Power Supplies Work?
Uninterruptible power supplies work by maintaining a continuous supply of electrical power to connected devices through one or more methods depending on the type of UPS. In the event of a power outage or significant power variation, the UPS instantaneously switches to battery power to provide uninterrupted electricity. This transition allows traffic control and telecommunications systems to continue functioning at optimal levels without interruption.
Benefits of Uninterruptible Power Supply Systems (UPSs)
For sectors in Singapore that rely heavily on uninterrupted power, such as data centres, healthcare facilities, and government operations, implementing a robust uninterruptible power supply (UPS) system is crucial. These systems provide a reliable power backup solution, ensuring that essential services and operations are maintained during power outages, brownouts, and voltage fluctuations, with significant benefits:
- Continuity in Critical Services: UPS systems are vital in maintaining the operation of critical infrastructure, preventing any disruption in services that could affect the public and economic activities.
- Enhanced Operational Safety: By providing a consistent power supply, UPS systems help avoid potential safety hazards that can arise during electrical failures, particularly in healthcare settings where power reliability is non-negotiable.
- Data Integrity and Security: For data centres and IT operations, UPS systems protect against data loss and hardware damage caused by sudden power disruptions, securing both operational data and customer information.
- Cost Efficiency and Reduced Downtime: By minimising the downtime caused by power disturbances, UPS systems help reduce the economic impact associated with outages and improve overall operational efficiency.
