How Rectifier module works?

Hi Experts, what is the use of Rectifier module?
How many we need to have on site?

Example: ZTE rectifier module, Huawei rectifier module.

Can we run site without rectifier module? If yes, How?

Kindly answer this please.
Or you have link to these special questions

Normally Telecom equipments require DC supply of -48 V. That’s what rectifier do conversion of AC to DC supply.
Rectifier modules come with different current rating 25, 50, 80, 100 A and so on.
Your requirement depends on site load.
Normally for a BTS site with 400 AH battery set with site laod of 50 A and 40 A for battery charge, 100 A capacity will do.
Hope it helps.
