ZL4830SA type rectifier module

Applied to ZBD48240/30 intelligent communication power system, detailed introduction is as follows:

I. Overview of the system

ZBD48240/30 intelligent communication power system is an unattended power supply designed for the demand of domestic communication power market. The system is composed of 48V30A high frequency switch rectifier module, the module adopts power factor correction, PWM pulse width modulation, current averaging and high reliable and fast protection and other advanced technologies, and AC distribution unit, DC distribution unit, ZLPM-C01 type monitoring module, ZL4830SA type rectifier module. ZLPM-C01 monitoring module can realize the local automatic management of the power system, and has RS232, RS485 communication port, can communicate with the remote monitoring center, realize the remote monitoring of the power system, management, monitoring and control of the system at any time, and can check the relevant working status parameters and fault history records at any time. With "telemetry, remote message, remote control" function.

The rectifier module and monitoring module of the ZBD48240/30 power system can be configured based on the capacity requirements. The monitoring module can detect the on-off of the eight-way output fuse or air switch, and has the function of secondary power-off protection and battery lower limit protection. The DC power distribution can connect to two batteries.

ZBD48240/30 power supply system is suitable for small and medium-sized program control switch, mobile communication, satellite communication ground station, microwave communication, but also for the corresponding other communication equipment power supply.

Second, the main functions and characteristics of the system
