Voltage Sensitive Split Charge Relay 24v/100A

The 24V 100A Voltage Sensitive Relay (VSR) is a heavy-duty relay designed for dual battery management in 24V automotive electrical systems. Perfect for trucks, buses, vans, and commercial vehicles, it automatically links the auxiliary battery to the main battery when the charging voltage rises, and disconnects when voltage drops—protecting the starter battery from being drained.

With a 100A continuous current rating, this VSR is ideal for powering high-demand 24V accessories such as inverters, fridges, and lighting systems. Featuring MCU smart detection, it automatically identifies the main and auxiliary batteries and charges accordingly. The compact screw-fit base design ensures straightforward installation and reliable performance in demanding environments.
