More information about 2pcs 12V-36V DC Digital Low Voltage Protector Disconnect Switch Cut Off Over Discharge Protection Module for Lead Acid Lithium Battery Solar Panel Lighting System

VOLTAGE THRESHOLD SAFEGUARD: Over-Discharge Protection: This battery management module provides a wide range of adjustability for discharging modes and parameter configurations. Users can define parameters to automatically disconnect the battery upon reaching a preset voltage threshold, effectively preventing over-discharge and prolonging battery lifespan (Important: The relay lacks an integrated power cutoff mechanism. Always manually cut off the power supply post-disconnection; failure to do so will drain the battery to 0V). Its customizable parameters allow precise adaptation of the power management system to exceptional operational needs and user preferences
SIMPLIFIED FUNCTIONALITY: To reset to factory defaults, turn off the device, press and hold both buttons together, then power it back on. The display will show “888” to confirm factory settings restoration. By default, the protection voltage is preset to 12V, paired with a 2V differential value, which defines the voltage gap required to disconnect and later reconnect the battery. In case of sudden power interruption, the system retains user-configured settings, safeguarding critical data and enabling uninterrupted workflow continuity upon reboot
FUNCTIONAL COVERAGE: This module operates as a voltage controller utilizing a relay-based mechanism to switch output power on/off. The relay serves exclusively as a switching component, maintaining the original voltage level without modification. Designed as a protective switching module, it does not integrate batteries. It is compatible with lead-acid batteries, lithium-ion batteries, and solar panel batteries (single units only)
PARAMETERS: Board Size:Board Dimensions: 57×42×19 mm (2.24×1.65×0.75 in, L×W×H); Input Voltage Range: DC 12–36V; Voltage Measurement Precision: ±0.1V; Energy Consumption: <1.5W under full load; Maximum Load Current: 20A (circuit breaker activation threshold)
NOTE: The miniaturized relay and thin circuit lines implemented in this module are a direct result of PCB board size constraints. To prevent irreversible relay contact damage, operational current must be strictly limited to 10A for systems below 12V and 8A for voltages exceeding 12V. Adherence to these thresholds is mandatory to ensure safe functionality under every conditions
