The interface features a 4-digit LED display, indicator lights, and four tactile control buttons.

: The module uses a physical 20A fuse for short-circuit safety. If a short circuit occurs, this fuse will pop and must be physically replaced (non-self-recovery).

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

With the output off, press the button repeatedly until you pass the U, I, and Memory address settings.

This menu is used to adjust the output voltage and current limit.

Understanding the precise electrical limits of your module prevents permanent hardware damage.

Connect to the positive terminal of your load (e.g., battery being charged, LED array, or motor controller).

Connect your load or destination battery to the and OUT- terminals using appropriately rated wire gauges. Step 3: Critical Safety Warnings

: If you attempt to set an output voltage lower than the input voltage, the current will pass directly through the diode unregulated, which can damage your load. Common Troubleshooting Steps

To safely charge batteries, set the to the battery's full charge voltage (e.g., 12.6V for 3S Li-ion) and set the Current to a safe charging rate (e.g., 2A). Connect the battery. The unit will start in CV mode, and as the battery reaches full charge, it will switch to CC mode, slowing the current naturally.
