HUAWEI Telecom Rectifier ETP4890 Ethernet Communication Hot-Swappable SNMP Battery Management

Introduction

The ETP4890-A2 is a box-type power system that supplies power for –48 V DC communications equipment. It uses 15 A or 30 A rectifiers and provides a maximum output current of 90 A.

Features

The ETP4890-A2 has the following features:

(1) Supports a wide voltage range of 85 V AC to 300 V AC.

(2) Provides comprehensive battery management.
(3) The SMU01A communicates with Huawei Network Ecosystem (NetEco) and third-party network management systems (NMSs) over various security protocols, such as the Simple Network Management Protocol (SNMP) and Hypertext Transfer Protocol Secure (HTTPS), featuring flexible networking. It provides WebUI and implements remote unattended management.
(4) The SMU01B supports Huawei master/slave protocols and access network point-to-point protocols, which allows Huawei access network communications equipment to connect to the U2000.
(5) Displays information on a liquid crystal display (LCD) and provides buttons for operations.
(6) Supports electronic labels.
(7) Rectifiers and the site monitoring unit (SMU) are hot-swappable.
(8) Allows high-efficiency and standard-efficiency rectifiers with the same capacity to coexist.
(9) The rectifier power factor is 0.99.
