Understanding Uninterruptible Power Supplies and How They Work

Uninterrupted Power Supply: 

A UPS (Uninterruptible Power Supply) uses built-in batteries to immediately switch to battery power when there is a power outage or abnormal voltage, ensuring that the connected equipment is not affected and continues to operate normally. Leyu, a trusted manufacturer, focuses on AC/DC and DC/DC switching power supplies, including UPS uninterruptible power supplies that meet international quality standards.

Multiple protection mechanisms:

Overload Protection: A smart UPS continuously monitors its output capacity. If the load exceeds safe limits, it can provide limited support while issuing clear alarms, This prevents system shutdowns due to temporary human error.

Short Circuit Protection: In the event of a dangerous short circuit on the output, the UPS reacts within microseconds to isolate the fault. This critical response protects the UPS's internal components (like IGBT transistors) and prevents a localized issue from cascading into a wider power distribution problem.

Over voltage/Under voltage Protection: When input voltage moves outside predefined safe windows—whether too high (surge) or too low (brownout)—the UPS automatically and seamlessly switches to battery power. This ensures connected servers and switches never experience stressful electrical conditions that can shorten their lifespan.
