Adjustable 30A Over Discharge Control Module for 10V to 60V Batteries What this module does and why you need it Protects batteries from deep discharge and overcharge by automatically disconnecting loads and stopping charging when preset voltages are reached. Supports a wide range of battery systems, including lithium and storage batteries, making it suitable for many mobile and stationary power setups. Precise control and reliable memory retention reduce the risk of battery damage and the need for frequent manual intervention. Key benefits Accurate voltage control: Adjustable protection with 0.1V resolution lets you fine tune overvoltage and undervoltage thresholds for safer battery management. current handling: Rated for 30A continuous current to support moderate loads without overheating or premature failure. Stable operation: Builtin 6 second delay on disconnection prevents nuisance trips during brief voltage fluctuations. Durable and reliable: Constructed on a thick circuit board using quality components, with nonvolatile memory to retain your settings after power loss. Important features Wide input range: Works with battery systems from 10V to 60V. Useradjustable settings: Set overvoltage and undervoltage points using the S1 input and front key buttons. Example typical settings are charge stop at 14.4V and load disconnect at 10.5V. Automatic functions: Module controls charging and load circuits automatically to prevent deep discharge and overcharge. Simple operation: Module is powered from the battery. Configure values in real time via the display and keys while in the field. Materials and performance Thick printed circuit board and quality components for long service life under repeated use cycles. Retains configuration parameters in memory after power off, ensuring consistent behavior after shutdown or battery replacement. Designed for reliable switching within the 30A rating and stable voltage control with 0.1V accuracy. Installation and use Wiring is straightforward: connect the battery first, then the charger. The module draws power from the battery to run its controls. Use the S1 input and onboard keys to set and adjust overvoltage and undervoltage thresholds as needed. Six second delay on load disconnect improves stability when voltage swings occur, reducing false disconnects. Practical applications Solar battery systems: Prevent deep discharge of battery banks in offgrid or smallscale solar installations by automatically disconnecting nonessential loads. Recreational vehicles and boats: Protect house batteries from overdischarge during extended periods of use or storage. Backup power and energy storage: Manage charge and discharge cycles for standby batteries used in telecom cabinets, UPS systems, or remote equipment sites.
