: A built-in fan ensures the module stays stable during long-term high-power operation. Status Indicators : Dedicated LEDs for (Active Output), (Constant Voltage), and

High voltage differentials (e.g., boosting 12V to 100V) naturally reduce efficiency and increase heat.

The BST900W can operate in a standard manual mode or utilize an automated special mode for advanced configurations. 1. Basic Operation: Setting Voltage and Current

If the website search fails, email or call support. Provide:

Long press SET for 10 seconds in normal mode. Select the slot and press OK to load. Automatic Startup

Usually on a silver sticker near the input terminals, or underneath a rubber footpad. The manual shows a diagram of the exact location.

Illuminates when the load exceeds the set current limit, forcing the unit to throttle voltage to maintain constant current.

Always double-check your connections before applying power. This is a step-up converter; the input voltage must always be lower than or equal to your desired output voltage. Step-by-Step Wiring

To access these, hold the button while powering on the unit. Function 0: Auto-output after power-on. (Default is OFF).

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.

Passive cooling via the stock aluminum heatsinks is generally sufficient if the ambient air is circulating.

The BST900W contains memory storage locations (0 through 9) to save frequently used configurations (e.g., specific profiles for charging 36V, 48V, or 72V battery packs).
