If none of these options work, I can try to help you find an alternative solution. Can you please tell me a bit more about what you need from the manual? Are you trying to troubleshoot an issue or learn how to use the amplifier?
OUT (Output), CV (Constant Voltage), CC (Constant Current).
I can provide custom wiring configurations or target parameters for your exact project. Share public link
: Do not exceed the maximum current threshold of 15A on either the input or output side. For high-load configurations running continuously over 10A, ensure the module is placed in a well-ventilated enclosure so the active cooling fan can control heat generation.
: You have likely hit your Constant Current limit. Increase your current ceiling limit or reduce the power demands of your connected load. bst900w manual
Use the and [-] buttons to adjust the voltage to your desired value.
: Illuminates when the module is actively regulating the voltage to your set limit.
Digital microprocessor with 4-digit LED/LCD display. Efficiency: Rated at ~85%. Protection: 20A fuse and active fan cooling. 📖 Manual & Operation Highlights
Is the module displaying a specific ?
Indicates that voltage is actively flowing to the output terminals. 3. Wiring and Installation
Do not block the cooling fan. If running above 10A continuously, add an external cooling fan.
Select AUTO-ON in the same menu to make the module output automatically upon power-on. 2. Setting Voltage and Current
Ensure the internal fan is spinning freely. Reduce the current limit or lower the ambient temperature surrounding the enclosure. If none of these options work, I can
A: Yes. The manual confirms "pass-through" charging is allowed. However, note that total output wattage may be reduced by 20% when input AC is connected.

Note: Because this is a converter, the output voltage must always be set higher than the input voltage ( ). It cannot step down voltages. 2. Hardware Layout & Interface
