About this item

  • DUAL PROTECTION: Still troubled by low battery life? This low voltage disconnect device, designed for 12V, 30A rated currents ystems like vehicles, solar, and alarms, acts as a dual protector between the 12V battery and the load. It not only increases battery life by three to four times but also protects the load from low voltage damage
  • DUAL MODE: This device features automatic and manual modes to intelligently manage battery and load connection based on your preset cut-off and reconnect voltages. Additionally, for enhanced battery protection, the device will immediately disconnect once the cut-off voltage is reached. Upon reconnecting the system power, it will wait for 5s to ensure voltage stability before re-engaging, thereby enhancing system stability
  • PRECISE ADJUSTMENT: Unlike similar products on the market that only allow selection among a few factory-set values, our freely adjustable voltage thresholds can be set with precision up to 0.1V, offering true intelligent customization. This not only allows the voltage settings to best meet your specific needs but also provides more accurate voltage testing capabilities, protecting your devices and battery
  • UPGRADED ALARM SYSTEM: To ensure you are promptly informed when the battery is at a low voltage, the buzzer will emit a slow warning alert when the voltage is within 0.5V of the disconnection threshold. After disconnection, it will sound a rapid alarm until the voltage drops by 0.3V, at which point the alarm will stop to prevent excessive power consumption. Additionally, you can manually cancel the alarm sound at any time
  • INTUITIVE INFORMATION: To facilitate your understanding of the battery and load conditions, we have incorporated an LED screen that displays various information including voltage, current, mute status, high temperature alerts, short circuit warnings, high current alerts, and abnormal temperature sensor readings, ensuring clarity at a glance



Product Description

1

Our low voltage disconnect template has four major functional innovations, adding a display screen that displays a variety of information, free adjustment (accurate to 0.1v), five-second delay access, and an improved alarm system.

1

It can prevent deep discharge when the battery is at low voltage, and will not be reconnected until 5s after the voltage returns to normal, ensuring circuit stability

3

Our freely adjustable voltage threshold can be accurate to 0.1V, which is truly intelligent customization, allowing the voltage setting value to meet your needs to the greatest extent possible

3

The device has automatic and manual modes. In automatic mode, it can intelligently manage battery and load connection or disconnection according to your preset cut-off and reconnection voltages. You can also manually connect or disconnect with one button

3

The information on the display will tell you what faults have occurred in your circuit (high temperature, short circuit, overcurrent, temperature sensor abnormality, etc.) so that you can solve the problem in time and protect your property

4

The bottom of the template is made of sheet metal with excellent heat dissipation performance, and heat dissipation holes are designed to prevent high temperature. In addition, we have also added measures to deal with high temperatures. When the temperature is higher than 80°C, the connection between the load and the battery will be automatically disconnected, When the temperature is below 70°C, it will automatically connect to avoid circuit accidents

Works great for shutting off direct wired ham radio in truck to save battery if I forget to turn it off at night.

Using this to prevent undervoltage on a lithium battery powered project. Seems to work well. It provides plenty of adjustment and I like the ability to bypass protection if needed.
