How does EPS overvoltage protection for fire emergency power supply work？
The overvoltage protection mechanism of fire emergency power supply EPS is as follows:
Mains voltage overlimit detection
The EPS system continuously monitors the input mains voltage. When the mains voltage exceeds a certain percentage of the rated input voltage (usually ±15% or ±20%), the system considers this to be an overvoltage situation.
Intercasting device action
Once an overvoltage is detected, the intercasting device of the EPS system will immediately act to cut off the mains supply to prevent the overvoltage from causing damage to the EPS system and the connected load.
Inverter power supply
In the case of mains overvoltage, the EPS system will switch to the inverter power supply mode, DC energy is provided by the battery, and the inverter will convert the DC power to AC power, and continue to provide stable power for the load.
System controller protection
EPS's system controller monitors the status of the entire system, including voltage levels, in real time. When an overvoltage is detected, the controller sends an alarm signal and takes measures to protect the system, such as cutting off the input power or adjusting the output to reduce the voltage.
Protection function
EPS system has perfect protection function, including input/output over-voltage protection, input surge protection and so on. When an overvoltage occurs, these protection functions are activated, ensuring the safety of the system and load.
Intelligent digital control technology
EPS uses intelligent digital control technology to achieve circuit control, parameter setting and operation management through high-speed microcontrollers and programmable logic devices. The system is capable of advanced self-testing and self-detection, fault analysis of all individual circuit connections, thereby effectively preventing and responding to overvoltage events.
Restore power supply
When the mains voltage recovers, the EPS system controller sends a signal to automatically shut down the inverter, and switches from the inverter power supply to the AC bypass power supply through the interthrow switch to restore the normal power supply.
CONCLUSION
Through the above mechanism, the fire emergency power supply EPS is able to protect the system and load from damage in case of overvoltage and ensure a reliable power supply in case of emergency.
