12V or 24V Dual-Power Automatic Transfer Module

Switch between compatible main and backup DC sources within a custom power assembly. This relay module provides a source-transfer component for a matched low-voltage project.

✅ Add automatic source selection - The module handles a supported transfer function between the connected DC sources.

✅ Choose the voltage version - Separate twelve and twenty-four-volt options let you match the board to the project.

✅ Keep the backup arrangement modular - A board-level component can join suitable sources and controls in a designed assembly.

A Transfer Component, Not a Complete Backup Supply

Select the module around the actual source voltages and load to be supplied. The relay and wiring arrangement must match the selected board's ratings for the transfer function.

Batteries, charging equipment and other required protective components are separate parts of the complete system. The module alone does not provide stored energy or a finished uninterruptible power supply.
