Emergency Power Supply Unit Testing & Inspection


As the name suggests, an emergency power supply unit is a critical electrical component of every building. Also called an Uninterrupted Power Supply, the unit is aimed at providing emergency power to load your equipment and systems during power failure. Contrary to a stand-by generator or auxiliary power system, this unit offers better and instant protection from mains power interruptions through one or more in-built batteries. For buildings that usually require high wattage, the unit can also be linked to flywheels or generators.

International Fire Codes require that the system should be able to efficiently run for about 5 to 15 minutes after power failure to allow time for bringing an alternative power source or proper shutdown of critical equipment. Emergency power supply units were originally used in naval ships during World War II. Today, emergency power supply units serve a wide range of applications including homes, offices, telecommunication centres, data processing enclosures, hospitals, shopping centers and factories.

While emergency power supply units are not limited to protecting specific electrical equipment, it typically protects vital devices like computers, machinery and other devices that could cause accidents, serious loss of data or disruption to critical business activities during unexpected power outages. However, the unit can only perform these functions if it is kept in proper condition at all times. Regular emergency power supply unit ensures that the system remains in better state for optimum performance at any time of need.

Emergency power supply units, especially the smaller ones rely on batteries to power equipment in case of power failure. Similar to other common batteries, these ones also lose charge and wear out after a period of time. Whenever that happens, the unit will not be able to function as required during a power failure, putting you and your devices in danger. Regular inspection and testing will ensure that the batteries and any issues that may hinder the performance of the unit are identified and fixed on time.
