All programmed parameters (limits, delays, functions) are automatically saved to internal memory and will not be lost during a power failure.

Answer: No. The DVB01 automatically saves all its settings to its internal memory. The settings are not lost when the power is turned off.

From , press and hold [SET] (long press) to enter the menu. You will now be in Parameter Setting Mode , where the relay is deactivated while you make changes.

The display will show P- 0 .

Power supply for the module (must match the rated 5V, 12V, or 24V). The target voltage source you want to measure/monitor. Relay Output Terminals: Common interface. Normally Open (shorts with COM when the relay is active).

Press and hold the button for roughly 2 seconds until the screen changes to display something like F-1 .

) allow for a delay in the relay action to prevent flickering caused by sudden, temporary voltage fluctuations. dvb01 user manual

The is a multifunctional voltage monitoring controller used for tasks like battery charge/discharge protection, over-voltage/under-voltage alarms, and automated load control. It features an industrial-grade microcontroller and a three-digit LED display for real-time voltage monitoring. Core Specifications

): Relay activates when voltage rises above the set upper limit and deactivates below the lower limit. Discharge Monitoring ( The settings are not lost when the power is turned off

: Positive power supply input (Connects to the operating voltage required by the module: 5V, 12V, or 24V). V- : Negative power supply input / Common Ground (GND).

: Triggering warning buzzers, cooling fans, or hazard lights during extreme overvoltage or undervoltage faults. Mode F3: Overvoltage Protection Mode (Threshold Drop Relay)

: Increase the numerical window size between V1 and V2. In modes like F3 and F4, the gap between V1 and V2 acts as software hysteresis. If they are too close together, natural ripple voltage causes the system to oscillate. The display will show P- 0

The DVB01 user manual is not just a startup guide; it’s a diagnostic tool. By systematically following its sections—setup, scanning, daily use, and troubleshooting—you can resolve 90% of issues without external help. Always keep a digital copy on your phone, and remember that even a poorly translated manual contains specific steps (e.g., “press 1111 for factory reset”) that no general advice can replace.

The DVB01 is an incredibly versatile and precise tool for voltage monitoring and control. With this guide, you should be well-equipped to set it up and put it to work in your own projects.
