Product Specifications: The Product Size: 57×42×19 mm ;Input: DC 12-36V ;Accuracy: ±0.1V ;Power Consumption: <1.5W ;Max Current: 20A
Product Operation: To reset: Power off, hold both buttons while powering on until "888" appears. Defaults: 12V protection voltage, 2V hysteresis (the voltage range between battery disconnect and reconnect). Settings are saved automatically during power loss.
Over-Discharge Protection: Set a voltage threshold to automatically cut off the circuit when battery voltage drops too low, preventing over-discharge and extending battery life. (Note: The relay itself does not cut power; manually turn off after disconnect to avoid power drain.)
Application: A protective switching module (battery not included) that uses a relay to control the output circuit. Suitable for lead-acid, lithium, and solar cells. Not for battery packs.
Note: Due to compact PCB design, use under 8A (under 12V: 10A max) to protect relay contacts.
