How does EPS overload protection for fire emergency power supply work?

The overload protection mechanism of fire emergency power supply EPS is as follows:

Output overload protection

If the output load of the EPS device exceeds the rated load of the EPS device in normal operating mode, the EPS generates an audible and visual alarm. In emergency mode, if the adjusted output power exceeds the overload capability of the EPS device, the EPS device automatically shuts down and generates an audible and visual alarm. When the load is restored to the rated load, the EPS should work normally.

Technical indicators of overload capacity

EPS equipment should have a certain overload capacity, such as normal operation for 10 minutes at 110% rated load and 1 minute at 125% rated load.

Automatic transfer Switch (ATS)

ATS is used to detect power outages and seamlessly transfer load from primary power to backup power (i.e. EPS system). This ensures the continuous power supply of critical fire protection equipment, while being able to switch in time in the event of overload, protecting the system from damage.

Monitoring and control

EPS systems are equipped with monitoring and control mechanisms to continuously monitor power status, battery health, and system function. This allows any problems to be detected in a timely manner and ensures timely corrective action, including protection in case of overload.

Regular maintenance

Regular maintenance and testing of EPS systems is essential to ensure their reliability and effectiveness in emergency situations. Regular inspections, battery testing, and system inspections can help identify and resolve potential problems, including inspections of overload protection features.

Audible and visual alarm

In the case of overload, the EPS system will emit an audible and visual alarm to remind the operator or the automatic system to take appropriate measures, such as reducing the load or switching the power supply, to protect the EPS system and connected devices.

CONCLUSION

Through these mechanisms, the fire emergency power EPS is able to respond in time in case of overload, protect the system and load from damage, and ensure the continuous operation of critical equipment and systems in emergency situations.
