Benefits •Easy to install •5.5" wire leads •7 position switch makes it easy to choose the shut-off voltage or "always on" LVD override ◦Disconnect voltage is selectable every 0.2V from 11.2V to 12.4V ◦Voltage is reconnected 1 Volt higher than the selected disconnect voltage. The circuit can be used with any type of batteries for example 12V, 9V, 6V, 5V etc. Discharging batteries beyond a critical low voltage can damage the batteries and/or load, and require a longer recharge interval. As a result, transistor Q1 is in ON and transistor Q2 gets switched off. Think of them as similar to circuit protection devices, but instead of terminating connection when voltage spikes, they disconnect when voltage drops too low, preventing damage to the batteries and load. Only you have to change the 5.1V zener diode value according to the battery voltage type. Fast, FREE delivery, video streaming, music, and much more. Fast, FREE delivery, video streaming, music, and much more. LOW VOLTAGE CUT-OUT This particular circuit will probably identify once the voltage of a 12v battery extends to a minimal level. Low Voltage Disconnects Low voltage disconnect switches are designed to protect batteries from excessive draw. Accuracy of the voltage display and Disconnect/Reconnect set points is more than adequate for MY needs. It's obvious purpose is to protect against draining a battery, however I used it to prevent overcharging a battery in a small / medium engine charging system (lawnmower, snowmobile). Adjust VR1 until LED1 turns off. My control works as described and as I expect it to for disconnecting batteries from a load at a predetermined minimum voltage. As well this one was priced very competitively. ❀Designed with a LED indicator to show if battery is under-voltage.

Waterproof 20A Low Voltage Disconnect w/Remote ON/Off and Alarm, 12V/24V Auto Detect. where V low is the low-voltage shutoff threshold. It has low power consumption when monitoring, and by switching its own power off upon low voltage detection, zero current draw once tripped to avoid further discharging your battery. An onboard LED indicates whether the 12V battery is enabled (on) or disabled (off). It reads about 2volts low and I assume it can’t be recalibrated. I used another relay as well for this purpose but it seemed to work well. Protection against load short-circuit & overload ...
