If you are looking to create a reliable and efficient electrical system for your 12 volt application, then you need to take a closer look at the wiring diagrams for Durite VSR (Voltage Sensitive Relay) split charge relays. These relays are designed to switch power between two batteries and are commonly used in applications such as caravans, boats and off-grid solar systems.
The Basics of 12 Volt Wiring
Before we dive into the specifics of Durite VSR split charge relays, let’s take a quick look at the basics of 12 volt wiring. In a 12 volt system, power is supplied from a battery or bank of batteries. The battery is connected to the load (such as lights, appliances or a motor) through a series of wires that make up the electrical system.
In order to create a reliable 12 volt system, it is important to understand the principles of electrical resistance and the need to use appropriate wire sizes for the load being carried. It is also vital to use quality components that are designed to handle the demands of a 12 volt system.
What is a Voltage Sensitive Relay?
A Voltage Sensitive Relay is a type of relay that is designed to automatically switch power between two batteries or banks of batteries. In a 12 volt system, this is typically a primary battery (such as a car battery) and a secondary battery (such as a leisure battery).
The Durite VSR split charge relay is a popular choice for this application due to its reliability and ease of installation. It is also a cost-effective solution that can greatly increase the efficiency and performance of any 12 volt system.

FAQ
What is a split charge relay?
A split charge relay is a type of relay that is designed to automatically switch power between two batteries or banks of batteries. In a 12 volt system, this is typically a primary battery (such as a car battery) and a secondary battery (such as a leisure battery).
What is a Durite VSR split charge relay?
A Durite VSR split charge relay is a specific type of split charge relay that is designed and manufactured by Durite, a leading supplier of electrical components for the automotive, marine and industrial sectors. Durite VSR split charge relays are known for their reliability and ease of installation, making them a popular choice for 12 volt applications.
Why do I need a split charge relay?
If you are running multiple batteries in your 12 volt system (such as a car battery and a leisure battery), then a split charge relay is essential for ensuring that both batteries are being charged and maintained properly. Without a split charge relay, one battery may become depleted while the other remains fully charged, leading to premature battery failure and reduced overall system performance.
How do I choose the right size of wire for my application?
The size of the wire you choose for your application will depend on a number of factors, including the amperage load, the length of the wire run and the type of insulation used. It is important to consult a wire size chart or consult with a qualified electrician to ensure that the wire you use is appropriate for your specific application.
Can I install a Durite VSR split charge relay myself?
Yes, a Durite VSR split charge relay is designed to be installed by anyone with basic electrical knowledge and skills. However, if you are unsure about any aspect of the installation process, it is always best to consult with a qualified electrician or mechanic.
What are the benefits of using a Durite VSR split charge relay?
Using a Durite VSR split charge relay can greatly increase the efficiency and performance of your 12 volt system. It ensures that both batteries are being charged and maintained properly, leading to longer battery life and reduced risk of system failure. It is also a cost-effective solution that is easy to install and maintain.
Conclusion
In conclusion, if you are looking to create a reliable and efficient 12 volt electrical system, then you need to consider the use of a split charge relay such as the Durite VSR. By following the wiring diagrams and guidelines provided in this article, you can ensure that your system is properly wired and functions at optimal performance.
