Includes input voltage protection and a 20A fuse for short-circuit protection.

is a powerhouse for hobbyists, capable of stepping up voltages from 8V all the way to 120V with a 15A current limit. However, its digital interface can be tricky if you don't have the manual handy. This guide breaks down everything from basic wiring to those "hidden" special functions. Quick Specs at a Glance 8V – 60V Output Voltage: 10V – 120V (Adjustable) Maximum Current: 15A Efficiency: ~85%

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 the internal fan is spinning freely. Reduce the current limit or lower the ambient temperature surrounding the enclosure.

While the output is active, pressing the (or the designated navigation arrow) allows you to cycle through different real-time data readouts:

The digital interface is the control center of the BST900W. While the exact button layout may vary slightly, the standard configuration uses a multi-function button and UP/DOWN arrow buttons.
