Huawei EPS30-4815AF Works
Huawei EPS30-4815AF power supply system is powered by electricity from completely. AC power supply through AC outlet and then through EMI filter transforming, into rectifier module, DC output of rectifier module through distribution unit summary is divided into 2 branches to load power supply, both branches are controlled by FU-1 (10A), FU-2 (20A) fuse, to provide users each way of overload, short circuit protection. The user’s battery is connected to the DC output side of the power supply system via FU-BT (20A) battery fuse and KM1 down-electric contactor, 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 parameters or user predetermined orders to work. If there is a power failure, the system will be replaced by battery power, with the battery discharge, the battery end voltage began to drop, when the battery voltage dropped to 45V (this is the default, the bottom can be set), the monitoring module will escalate the DC undervoltage alarm signal; When the voltage drops to the battery protection voltage point (43V (this is the default, the bottom can be set), the monitoring module controls the action of the KM1 contactor, disassembles the battery power supply system, protects the battery from overdischarge, and the power supply system will stop working. When the external power supply is restored, the system returns to normal operation at the same time (the above monitoring data is the system fault and can be reset by the user).
Huawei EPS30-4815AF in addition to battery discharge protection, the system is also designed with battery overheat 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. The battery over temperature protection is allowed by default. The battery over temperature protection point is set from 40 to 70 degrees C (the default is 53 degrees C), and the recovery point is set 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, flood, smoke, etc.) and backup detection volumes through an external signal transfer box.
Function of the Huawei EPS30-4815AF
EPS30-4815AF power supply system allows 1 AC input to 2 DC outputs, DC power distribution, and supports connecting 1 set of battery to monitor the battery by the monitoring module.
The EPS30-4815AF power system can also gather and report the status of various sensors and backup detections through an external sensor transfer box.

Huawei EPS30-4815AF 1U Rectifier Modules Included 48V 30A Power Supply: A Comprehensive Review
The Huawei EPS30-4815AF is a 1U rectifier module included 48V 30A power supply system that provides -48Vdc DC power voltage output. This system is designed to convert 220V/110V AC power to -48V DC power, with a maximum output of 30A [[3]]. In this article, we will explore the features, configuration, and working principles of the Huawei EPS30-4815AF power supply system.
System Configuration
The Huawei EPS30-4815AF system consists of 1-2 rectifier modules (power supplies) that support hot-swapping, with a working range of up to 90-290Vac [[2]]. The system also includes a monitoring module (PMU) with battery management and power system monitoring functions, equipped with appropriate sensors to realize environmental monitoring. The PMU provides RS232, RS422 communication interface, making it easy to realize remote monitoring and unattended operation.
Working Principles
The Huawei EPS30-4815AF power supply system is powered by electricity from the AC power supply through an AC outlet, which is then filtered and transformed into a rectifier module. The DC output of the rectifier module is distributed into two branches to load power supply, with each branch controlled by FU-1 (10A) and FU-2 (20A) fuses, providing users with overload and short circuit protection. The user’s battery is connected to the DC output side of the power supply system via FU-BT (20A) battery fuse and KM1 down-electric contactor, providing overload and short circuit protection to the battery.
Battery Protection
The Huawei EPS30-4815AF system is designed with battery discharge protection and battery overheat protection. In the event of a power failure, the system will switch to battery power, and when the battery voltage drops to 45V (default, adjustable), the monitoring module will trigger a DC undervoltage alarm signal. When the voltage drops to the battery protection voltage point (43V, default, adjustable), the monitoring module will control the action of the KM1 contactor, disconnecting the battery power supply system and protecting the battery from overdischarge.
Battery Overheat Protection
In addition to battery discharge protection, the system is also designed with battery overheat protection. If the battery temperature exceeds the protection point (default 53°C, adjustable between 40°C to 70°C) for 30 consecutive seconds, the monitoring module will unconditionally control the battery power until the battery temperature is below the recovery point (5°C lower than the protection point), and trigger an alarm.
Environmental Monitoring
The Huawei EPS30-4815AF power supply system can collect and report the status of various sensors, including temperature, humidity, and other environmental factors.
Conclusion
the Huawei EPS30-4815AF 1U rectifier module included 48V 30A power supply system is a reliable and efficient power solution for various applications. With its hot-swappable rectifier modules, advanced monitoring module, and robust battery protection features, this system is ideal for providing -48V DC power voltage output in a variety of environments.
Where to Buy
The Huawei EPS30-4815AF power supply system is available for purchase from various online retailers, including Elecok [[1]].
