Emergency battery switching controller Key benefits Ensures uninterrupted DC power: automatically selects the main power source when available and switches to the battery when mains is lost, preventing downtime for critical equipment. Simple installation and reliable connections: screw terminals provide a secure, toolfriendly wiring method for quick integration into existing systems. Broad compatibility: builtin automatic detection supports any DC supply between 12V and 48V, making the controller suitable for a wide range of batterybacked setups. What it does Monitors the main power source terminal and connects to the main supply while it is present. Automatically switches to battery power when the main supply fails, then returns to main power when it is restored. Identifies input voltage in the 12V–48V DC range without manual setting. Important attributes Function: emergency battery switching / automatic DC power switchover. Compatibility: automatic voltage recognition for 12V to 48V DC systems. Connectivity: screw terminals for convenient, secure wiring. Operation: automatic, maintenance switching to prevent service interruption. Typical applications Incubators and small medical or laboratory equipment that require continuous DC power. Laptops and portable workstations using DC backup systems to avoid data loss. Network equipment and small servers where automatic failover preserves connectivity. Why customers choose this controller Minimizes manual intervention: automatic detection and switching reduce the need for monitoring and manual changeover. Versatile across DC systems: supports a wide voltage range so it fits many existing battery and power configurations. Practical and straightforward to wire and deploy using screw terminals. Compatibility note Designed to be connected to a main power source terminal and a battery; will select the main source if present and switch to battery when the main source is absent.
