3200W 60A Rectifier Used In Telecommunication

3200W 60A Telecom Power Supply Rectifier Input 220VAC Output 48VDC

Two 30A Rectifier Module One Monitoring Module

Model: GPE4860G

I. System configuration

The system consists of distribution unit, rectifier module (up to 2 sets) and 1 monitoring module. The configuration is optional, as following table:

II. Operating principle

Under normal conditions, every parameter of rectifier modules and distribution unit are all under control of the monitoring module, operating according to the pre-set parameter or user’s commands. If AC mains fault, the system will be powered by the battery. With the battery discharge, the terminal voltage of the battery starts to descend. When the battery voltage is under 42V±0.5V, the monitoring module reports battery under voltage alarm signal and cuts off the load output, then the power system stops working. When the external AC mains recovers, the system will resume to the normal work state. (All above monitoring data are system default values that users can reset).

Except for battery over-discharge protection, battery or load over-temperature protection is prohibitive under default, users can send command to activate or inactivate according to the demanding. When the operating temperature is 55°C or more, power de-rating will be employed by system (at 65°C,system output power is 2600W).

III. Application

■ Small scale program controlled exchanger

■ Access network

■ Transmission equipment

■ Mobile communication

■ Satellite communication ground station

■ Microwave communication
