Bst900w Manual ((link)) [2026 Update]

The is a high-power DC-DC CNC boost converter designed to step up voltages from 8V–60V to a regulated 10V–120V output. It features a digital interface for precise adjustment of both voltage and current, making it popular for battery charging and LED driving. 🛠️ Technical Specifications Input Voltage: 8V – 60V Output Voltage: 10V – 120V Input Current: 0 – 15A Output Current: 0 – 15A (Maximum power is 900W) Efficiency: ~85%

Press the OK button to activate the output. Ensure your target voltage is configured higher than the supply voltage. The module shuts down unexpectedly under load.

A "rotation display" mode can be enabled to automatically cycle through all real-time parameters. bst900w manual

At high power outputs, the module can become very hot. Ensure adequate ventilation or use an external fan.

The (or B900W) is a high-power numerical control DC-DC boost converter designed to step up voltages from 8-60V to 10-120V . While it offers advanced features like memory storage and digital precision, user reviews suggest its real-world performance often falls short of the "900W" marketing claim. 💡 Core Specifications Input Range: 8V to 60V DC. Output Range: 10V to 120V DC. Max Current: 15A (Input/Output).

4-digit LED or LCD showing Volts (V), Amps (A), Watts (W), and Capacity (Ah) Cooling: Built-in fan for thermal management 🕹️ Basic Operation Guide Primary Controls SET Button: Toggles between setting voltage and current. Up/Down Arrows: Increases or decreases the selected value. OK Button: Turns the output ON or OFF . Indicators: OUT: Active output. CV: Constant Voltage mode. CC: Constant Current mode (active during current limiting). ⚙️ Advanced Programming Data Storage and Recall The device can store up to 10 groups of settings (0–9). Ensure your target voltage is configured higher than

[ Power Source ] ---> ( IN+ ) [ BST900W ] ( OUT+ ) ---> [ Your Load / Battery ] [ (e.g., 12V / 24V) ] ---> ( IN- ) [ Module ] ( OUT- ) ---> [ (e.g., 48V / 72V) ]

By default, the BST900W requires you to manually press to output power every time it boots. You can change this behavior so it outputs power automatically upon receiving input voltage: With the module powered off, press and hold the OK button. While holding OK , turn on your input power source. The screen will display a code such as 0-F0 , 0-F1 , or 0-F2 .
