Product Description

VSR 12/24v – 140amp Dual Sense

The 140A 12/24V Voltage Sensitive Relay (VSR) is the ultimate solution for efficient and safe battery management in dual-battery systems. Designed for use in marine, caravans, camper vans, and RVs, this intelligent relay ensures seamless charging and power distribution without compromising your starting battery’s reliability.

Key Features:

• Automatic Battery Separation: When the engine starts, the VSR isolates the starting and auxiliary batteries, ensuring only the starting battery is charged initially.
• Smart Charging Activation: At 13.2 volts, the VSR engages, enabling both batteries to charge simultaneously.
• Protective Disengagement: When the voltage drops below 12.8 volts, the VSR disconnects the auxiliary battery to protect the starting battery from being drained.
• No Voltage Loss: Ensures maximum power efficiency.
• Intelligent Battery Monitoring: Prevents unnecessary switching and optimizes battery life.
• Starter Battery Priority: Gives precedence to the starting battery for enhanced reliability.
• Bipolar Switching & Voltage-Dependent Functionality: Adapts seamlessly to 12V or 24V systems for versatile application.

Applications:

Ideal for vehicles and setups requiring dual-battery systems, including:

• Marine vessels
• Caravans
• Camper vans
• Recreational vehicles (RVs)
