Undervoltage Battery Cut-Off Module

Backup power units and battery power supplies need to stay in a happy middle ground between charged and discharged to ensure they are not damaged. Total discharge occurs when a battery has lost all its stored up voltage and energy. Batteries are always discharging whenever they are plugged out of a charger. But running completely flat can decrease your battery's future lifespan and render them useless in time. Clever makers find ways to prevent this by using intelligent Cut-Off Modules like this one that cuts the power of the battery to prevent total discharge.

This Undervoltage Battery Cut-Off Module operates with 5A at 12V DC and will cut off the power of your battery when the battery voltage falls to 10.6V. This protection is especially useful for standing backup power units in any alarm or access control system. The battery will become permanently damaged if allowed to totally discharge. This Cut-Off Module provides connection points for both battery leads and battery terminals. It features automatic restoring of power when the battery is once again connected to a charger voltage. In addition to being a great protection to your battery’s long life, the Undervoltage Battery Cut-Off Module lets you know exactly when your battery is running low with an LED indicator. This Cut-off Module’s small size makes it an easy little module to install and a great helper to maintaining the health of your backup batteries.

Please note: The Undervoltage Battery Cut-Off Module is supplied in two versions, as seen in the product photos above. You may receive either module board in your order, but rest assured, both are equal in quality and function.
