Dvb01 User Manual ((hot)) -

5 Programmable modes (Voltage measurement, Charge monitoring, Discharge monitoring, etc.). 2. Wiring Interface The DVB01 features two main terminal blocks: Power & Input Side (4 Terminals): DC+: Positive power supply for the module. DC-: Negative power supply for the module.

Negative terminal of the voltage being measured (Common ground). Relay Output Side (3 Terminals):

The relay closes when the voltage is above the upper limit (V2) and opens when it drops below the lower limit (V1). Ideal for protecting batteries from over-discharge. dvb01 user manual

Are you planning to use the DVB01 for a or a DIY battery charger ?

The relay remains inactive. The screen simply acts as a digital voltmeter. DC-: Negative power supply for the module

Use the SWI button to move the cursor and the NUM+ or NUM- buttons to change the digit.

Disconnects from the load when the relay is triggered. 3. Key Functions & Modes Ideal for protecting batteries from over-discharge

The DVB01 operates using five distinct logic modes (F1–F5). To switch modes, long-press the button.

While the DVB01 can measure up to 100V, the relay is a mechanical switch. Always ensure your load does not exceed the rated amperage (usually 30A), and use an external fuse for high-current applications to prevent fire hazards.
