Hybrid Telecom Power System 48VDC 300A/600A

Description

OD-TRSS series telecom power system is an integrated solar telecom power supply that can be directly used outdoors.

 

Working Principle:

Normally,the power system runs in a parallel floating charge state,that is,the rectifier module,solar module,load,and battery work in parallel.Solar modules and rectifier modules provide floating charge current for power communication devices and batteries.If the output power of the solar module is insufficient to feed all the loads,the rectifier module will provide supplementary power for the communication devices.

When the mains power is off,the rectifier module stops working.If the solar power supply is normal,the solar module will feed the communication devices and charge the battery.If the output power of the solar module is insufficient to feed all the loads,the battery will provide supplementary power for the communication devices.

When the mains power is off,the rectifier module stops working.If the solar energy fails at the same time,the communication devices will be powered by batteries.When the battery discharge continues for a period of time to the point of the generator start,.the monitor sends start signal to the generator.Generator provides AC input power for the rectifier module,then the rectifier can supply power to the communication devices again and charge the battery to compensate for the consumption.When reaching the stop point of the generator,the monitor unit sends out a stop signal to the generator,and the generator turns off.
