Description

The offered product is a Huawei ETP4860-B1A2 telecom power supply unit, equipped with an SMU11C controller and two R4815G1 rectifiers. It is designed to power various types of telecommunication devices with buffer backup support. It has 5 output connectors (LOAD1 - LOAD5) and 1 connector for connecting external batteries (BATT). The input supports standard AC voltage (full range 85 - 300 V AC). The output voltage ranges from 42 to 58 V DC, with a nominal voltage of 53.5 V DC. The package includes two R4815G1 rectifiers, each with a power output of 1000 W, providing a total power of 2000 W for the entire power system. The device does not support adding an additional rectifier.

The device is equipped with an SMU11B controller featuring signal and alarm connectors. Communication is facilitated through an RJ45 console port and a Fast Ethernet port. It supports management via a graphical web interface.

Embedded power supply with 5 outputs

ETP4860-B1A2 is a telecommunications power system equipped with 5 output connectors for connecting loads. Next to them, there is a battery connector (BATT) for connecting external batteries. By using batteries, you can provide backup power to the entire system. In case of a main power failure, the device will switch to battery operation. The output voltage range is 42 to 58 V DC, with a nominal voltage of 53.5 V DC.

Two R4815G1 rectifiers

In the package, you will find two rectifiers, R4815G1, each with a power rating of 1000 W, totaling 2000 W. The telecommunications power system has two slots for rectifiers, so you cannot add another one. The input voltage range is 85 - 300 V AC, with a nominal voltage of 220 V AC, 50/60 Hz. R4815G1 rectifiers are hot-swappable and feature active cooling with built-in fans. They are distinguished by their high efficiency, which exceeds 95%.

SMU11B module, Web management

The SMU11B control module features input signals (including connections for battery temperature sensor and battery voltage) and alarm outputs. It communicates via one RJ45 console port and one fast Ethernet port (10/100 Mb/s). The module does not include an LCD display and can be managed through a graphical web interface.
