The BST900W supports two primary operational modes, as explained in various product manuals. The method to activate them can be found by holding the button for 10 seconds to enter the startup menu.

The BST900W features 10 built-in memory registers to quickly save and recall frequent profiles. Saving a Profile

After setting your desired Voltage and Current, press and hold the SET button until the display shows a blinking memory slot identifier (e.g., M-0 ). Use the arrows to select a slot, then press OK to save. Illuminates when the module is successfully regulating a

The BST900W does not have built-in reverse polarity protection on the input side. Accidentally swapping positive and negative inputs will immediately destroy the board. Always double-check connections with a multimeter.

Input voltage is too low, or input polarity is reversed.
