An Emergency Power Supply is a backup system designed to provide electricity during power outages. It ensures that essential devices, such as lights, medical equipment, and communication tools, continue to function when the main power source fails. This can be achieved through various means, including batteries, generators, or uninterruptible power supplies (UPS). These systems are crucial for both homes and businesses, especially in areas prone to natural disasters or unreliable power grids. By maintaining power during emergencies, an Emergency Power Supply helps prevent disruptions and ensures safety and continuity in daily operations.
