How does EPS short circuit protection for fire emergency power supply work

The short-circuit protection mechanism of fire emergency power supply EPS is as follows:

Intelligent automatic charger

EPS special short circuit protection Intelligent automatic charger uses photoelectric isolation technology, integrated short circuit impedance detection circuit. This design can close the main circuit power device immediately at the moment of short circuit, so as to avoid the impact damage of the power device by the short circuit current.

Over current and short circuit protection

The output circuit of the EPS switchboard has over current and short circuit protection functions, and its protection device will have an alarm contact when it is operated. All contacts should be connected to the indicating and self-checking system to ensure a timely response in the event of a short circuit.

Perfect protection function

EPS system has input and output over and under voltage protection, input surge protection, phase sequence protection, battery over charge and over discharge protection, output overload and short circuit protection, high temperature protection and other system protection and alarm functions. These functions ensure that EPS can quickly cut off power in the face of abnormal situations such as short circuits and protect the system.

Dynamic characteristics and feedback control

EPS adopts a variety of feedback controls such as instantaneous control mode and effective value to achieve high dynamic regulation and reduce the output voltage distortion. This control helps to respond quickly and reduce damage when a short circuit occurs.

Intelligent communication and linkage

EPS system has RS232 and RS485 communication ports to achieve multi-purpose communication and remote monitoring. In an emergency, such as a short circuit, the system can provide feedback signals of the dry contact status and fire linkage signals as required to achieve rapid response.

Static switching technology

EPS uses static switching technology to adapt to computer monitoring equipment and some lamps requiring short switching time. The fast power failure detection software is designed to achieve a conversion time of less than 3 milliseconds, which helps to quickly switch over and reduce the impact when a short circuit occurs.

CONCLUSION

Through the above mechanism, the fire emergency power supply EPS can respond quickly when a short circuit occurs, cut off the power, protect the connected load and the system itself from damage, and ensure the continuous operation of critical equipment and systems in emergency situations.
