This is an under-voltage switch controller designed to disconnect the load when the voltage drops below a predefined level. Once the battery voltage rises to a specified threshold, the module will automatically reconnect the load. This controller serves to protect batteries from over-discharge, thereby extending their lifespan. Both the turn-off and turn-on voltage settings are easily adjustable with the push of buttons. It is suitable for various 12V-48V storage and lithium battery discharge protection modules. Specifications include: - Battery voltage: 12V-48V - Input voltage: DC 9-60V - Control Precision: 0.1V - Power consumption:
