HUAWEI OLT Power Supply Power Converter ETP48100-B1-50A
ETP48100B1 is a Modualar AC/DC Converter with as many as 4 Power Inputs
Each with Max 25A, it is capable of converting 200V/110V AC power to 48V DC Power
The device had two R850G2, making its total output power can be 100A
HUAWEI ETP48100B1 had many protections, so the rectifiers show very high effieiency
