    I bought an ETP-4830-A1 at online, it equipped on SMU1C by default, but my client need an extra SMU01A monitor module, i contact sales, they provide an extra one.

    I need AC to DC power convertor with backup barrties, while ETP48100 doesn not support this function, so I choose ETP4830.

  6. Frantisek

    I bought an Huawei OLT MA5683T bundle with DC power board before, and work well very. Thanks!
    Now my customer required an power convertor for it, but need to support Web UI. I need to look for it.
