Huawei NetSure 212 C23 description
Huawei EPS30-4815AF power supply system is an AC/DC embedded power supply system that provides -48Vdc DC supply voltage output.
Huawei EPS30-4815AF system configuration
1-2 rectifier modules (PSUs) that support hot-swapping, and rectifier modules have a working range of up to 90-290Vac. System configuration monitoring module (PMU) with battery management function and power system monitoring function, equipped with appropriate sensors to achieve environmental monitoring, and provide a number of sets of backup monitoring capacity, can provide RS232, RS422 communication interface, easy to achieve remote monitoring and unattended.
Huawei EPS30-4815AF works
Huawei's EPS30-4815AF power system is powered by electricity from all the way. AC power supply through the AC socket and then through EMI filtering processing, into the rectifier module, the DC output of the rectifier module by the distribution unit summary is divided into 2 branches to the load power supply, the two branches are controlled by FU-1 (10A), FU-2 (20A) fuse, to provide users with each way of overload, short-circuit protection. The user's battery is connected to the DC output side of the power system via the battery fuse FU-BT (20A) and the down-electric contactor KM1, which provides overload and short-circuit protection to the battery.
Huawei EPS30-4815AF system under normal circumstances, the rectifier module, power distribution unit of various parameters are controlled by the monitoring module, according to its predetermined parameters or user commands to work. If there is a power failure, the system will be replaced by battery power, with the discharge of the battery, the battery end voltage began to drop, when the battery voltage dropped to 45V (this is the default value, the background can be set), the monitoring module escalates the DC undervoltage warning signal; When the voltage drops to the battery protection voltage point (43V (this is the default, the background can be set), the monitoring module controls the contactor KM1 action, disconnects the power system from the battery, protects the battery from discharge, and the power supply system will stop working. When external power is restored, the system returns to normal operation at the same time (the monitoring data above is the system default and can be reset by the user).
Huawei EPS30-4815AF In addition to battery discharge protection, the system is also designed with battery over-temperature protection: if the battery temperature exceeds the protection point for 30 consecutive seconds, the monitoring module unconditionally controls the battery power until the battery temperature is below the recovery point, and alerts. Battery over temperature protection is allowed by default. The battery over temperature protection point is set from 40 to 70 degrees C (default is 53 degrees C), and the recovery point is fixed to be 5 degrees C lower than the protection point.
In addition, the power system can collect and report the status of various sensors (temperature, humidity, door magnetism, flooding, smoke, etc.) and backup detection volumes via an external signal transfer box.
Huawei EPS30-4815AF function
The EPS30-4815AF power system enables 1 AC input to 2 DC outputs, dc power distribution, and supports the connection of 1 battery set to manage the battery through the monitoring module.
The EPS30-4815AF power system can also collect and report the status of various sensors and backup detections via an external sensor transfer box.
