Wide Voltage Range Telecom Rectifier Module DC Power System With PDU / Rectifiers / SMU

Wide Voltage Range DC Power System With PDU / Rectifiers / SMU

1.System Introduction

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

2. System Features

• Supports a wide voltage range of 85 V AC to 300 V AC.

• Provides comprehensive battery management.

• 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.

• 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.

• Displays information on a liquid crystal display (LCD) and provides buttons for

  operations.

• Supports electronic labels.

• Rectifiers and the site monitoring unit (SMU) are hot-swappable.

• Allows high-efficiency and standard-efficiency rectifiers with the same capacity to coexist.

• The rectifier power factor is 0.99.
