  1. Italy
    second time to order AC/DC converter with SMU01A from Thunder, really fast response and good service, highly recommended.
  2. Colombia
    Before we bought ETP48100 50A converter, but in some rural area, power supply is not stable, I know ETP4890 support battery, but can we install 4pcs 12V 100A batteries on the device?
  3. Global
    Compared with ETP48100, it is much more expensive, but this time my customer needs the function of WebUI Remote Manage, so only can choose it with SMU01A modules. Next time i will choose ETP48100.
