The SRNE DB12 Distribution Box is an intelligent 12-way DC power distribution and switching system designed for campervans, motorhomes, caravans and other recreational vehicles. It provides a centralised solution for distributing battery power to onboard equipment while allowing individual electrical circuits to be monitored and controlled.
Featuring 12 independently switchable DC outputs, the DB12 can manage equipment including lighting, water pumps, refrigerators, fans and entertainment systems. Each circuit has its own fuse, providing a convenient alternative to traditional distribution boards and separate switches.
With built-in Bluetooth, RS485 and CAN communication, the DB12 integrates with compatible SRNE control displays, including the RM12, RMA4 and RMA7, allowing electrical circuits to be operated from a central touchscreen or compatible smartphone application.
• 12-Way DC Distribution – Provides 12 individually controlled outputs for campervan and motorhome electrical equipment.
• Multiple Output Ratings – Three 30A circuits, three 20A circuits and six 10A circuits.
• Smart Circuit Switching – Switch individual electrical loads on or off through compatible SRNE displays or the mobile app.
• Built-in Bluetooth – Wireless monitoring, parameter adjustment and load control using a compatible smartphone.
• Integrated Fuse Protection – Each output features a replaceable fuse for electrical circuit protection.
• Permanent Power Option – Selected circuits can be configured for continuous power rather than normal electronic switching.
• Inverter Remote Control – Dedicated connection for remotely switching a compatible inverter on or off.
• Battery Protection – Provides battery overvoltage, over-discharge and total load overcurrent protection.
• RS485 & CAN Communication – Supports integration with compatible SRNE monitoring and control equipment.
• 12V/24V Compatibility – Supports both 12V and 24V electrical installations on the applicable model version.

The SRNE DB12 is designed for fixed installation in a dry, protected and adequately ventilated location within the vehicle.
The distribution box connects to the leisure battery system and provides individually fused DC outputs for compatible electrical appliances. Appropriate cable sizes, upstream protection and correctly rated circuit fuses must be selected according to the installation requirements.
The DB12 distributes DC battery power to up to 12 separate electrical circuits while providing electronic switching and monitoring. It is designed to replace or simplify conventional DC distribution arrangements in campervans and motorhomes.
Yes. The DB12 can control compatible 12V or 24V DC appliances, including lighting, water pumps, fans, refrigerators and other onboard equipment. Each circuit must remain within its specified current rating.
Yes. The DB12 features built-in Bluetooth connectivity, allowing compatible smartphones to access circuit switching, monitoring and parameter settings through the SRNE mobile application.
Yes. The DB12 supports communication with compatible SRNE control displays, including the RMA7, RMA4 and RM12. These provide a convenient central interface for operating connected electrical circuits.
Yes. The DB12 includes a permanent-power arrangement that allows selected circuits to remain powered independently of normal electronic switching. This can be useful for equipment requiring an uninterrupted DC supply.
Yes. All 12 output circuits feature individual replaceable fuses. The outputs are divided into three 30A, three 20A and six 10A circuits, allowing different electrical loads to be connected according to their requirements.
Yes. The DB12 includes a dedicated inverter remote switching connection. This can be used with compatible inverters that support the required external on/off control arrangement.
The DB12 does not convert battery power into 230V electricity. A separate inverter is required.
Yes. The DB12 supports compatible lithium and lead-acid battery systems. Battery protection voltage settings should be configured to suit the battery manufacturer's recommendations.
The DB12 is a power distribution and control device, not a battery charger or battery management system.
