Bst900w Manual ((install))

: Press the SET button. When the voltage digits flash, press the Up (▲) or Down (▼) arrow keys to achieve your target voltage level.

Typically, the four buttons are:

From the main idle screen, press and hold the button for 3 seconds. The screen will display the last loaded memory slot prefix. Use ▲ or ▼ to locate your desired slot.

The 4-character seven-segment LED display shows parameters in real-time. By default, it alternates between and Current , but it can be configured to cycle through Power (W) and Capacity (Ah) . bst900w manual

: Enabled. Output turns live instantly when input power is connected. F2: Display Cycle Mode

: Never exceed 15A on either the input or output side. For prolonged tasks over 10A, place an external cooling fan blowing directly over the inductors.

Save/recall parameters + display power (W) and capacity (Ah). : Press the SET button

Check the ON/OFF indicator. If it is off, press the ON/OFF button. Ensure input voltage is connected correctly.

Quickly set voltage (V) and current (I) for basic tasks.

The module allows storing frequently used settings (voltage/current profiles). The screen will display the last loaded memory slot prefix

The manual highlights a "10 groups memory" feature, allowing users to store and recall specific parameters instantly—a critical function for repetitive testing or multi-stage projects. Dual Operating States: It outlines the transition between Constant Voltage (CV) Constant Current (CC)

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

Constant Voltage mode. The module is maintaining the set voltage, and the current is within safe limits.
