Power input
Redundant modules typically receive inputs from multiple power sources, which can be different battery packs, different power lines, or different power devices.
Power monitoring
The monitoring system inside the module will monitor the status of all input power sources in real time, including parameters such as voltage, current, and temperature.
Load allocation
Under normal operating conditions, the main power supply is responsible for supplying power to the load, while the backup power supply is in standby mode. Load distribution can be achieved through static or dynamic switches to ensure smooth switching of power supply.
Fault detection and switching
When the main power supply fails (such as voltage drop, abnormal current, or power failure), the redundant module will automatically detect the fault and activate the switching mechanism to switch the load to the backup power supply.
Redundant mode
Redundant modules can be configured in multiple redundancy modes, such as N+1, N+2, etc., where “N” represents the minimum number of power sources required for normal operation, and “+1” or “+2” represents the additional number of backup power sources.
Power synchronization
In some applications, to ensure that power switching does not cause instantaneous power outages to the load, redundant modules use synchronization technology to ensure that the phase, frequency, and voltage of the power supply remain consistent during the switching process.
protection mechanism
Redundant modules typically include overload protection, short circuit protection, overheating protection, etc., to prevent damage to the power supply or load.
Remote monitoring and control
Many redundant modules support remote monitoring and control, allowing operators to monitor power status through networks or communication interfaces and manually switch when needed.
Maintenance and testing
Redundant modules typically provide maintenance and testing functions, such as regular self checks, load testing, and fault simulation, to ensure that the system can function properly in emergency situations.
