Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of alarm circuits, and in particular relates to a UPS alarm circuit. Background Art
[0002] In existing power supply systems, uninterruptible power supplies (UPS) are widely used to ensure the continued operation of critical equipment in the event of a power outage. UPS power outage alarms, as crucial auxiliary devices, can promptly issue an alert upon detecting a utility power outage, alerting management to take countermeasures. However, mainstream UPS power outage alarms currently on the market suffer from the following shortcomings: some are prone to malfunction during extended operation or in complex environments, leading to false or missed alarms and compromising emergency response efficiency. Traditional alarm designs often overlook the need for low power consumption, resulting in high energy consumption during extended standby periods, increasing operating costs. Most alarms offer only simple audible and visual alarm functions and lack integration with remote monitoring systems, limiting their application in modern management. Different UPS system models have varying interfaces, making existing alarms incompatible with all models and increasing deployment complexity and cost. While UPSs continue to operate after a utility power outage, some unattended systems may continue operating until their batteries deplete, potentially leaving critical data on computers unattended. This can lead to significant inconvenience for businesses and users, leading to data loss.
