Life Racing Master Relay | High-Current Solid State Isolator

The Life Racing Master Relay is a professional-grade solid-state battery isolator designed to provide ultimate reliability and safety for vehicle electrical systems. Capable of handling massive current loads without the failure points of mechanical relays, this unit integrates directly into the vehicle's CAN-bus network for real-time diagnostics and automated safety shutdowns.

Extreme Power Handling

Engineered to manage high-demand electrical systems and heavy engine cranking:

• 200A Continuous Current: Robust enough for the most power-hungry race car architectures at 25 degrees Celsius.

• 1000A Peak Current: Effortlessly handles the extreme in-rush currents required for high-compression engine starting.

• Solid-State Reliability: No moving parts means no contact arcing or mechanical failure due to high vibration or G-loading.

Intelligent Safety & Diagnostics

• CAN-bus Integration: Transmits critical data over the vehicle network for logging and diagnostics, allowing for intelligent monitoring of the main power supply.

• Automated Safety: Can be integrated with ECU or PDU logic to perform emergency power cuts based on crash detection or fire suppression triggers.

• Built-in Short Protection: Integrated circuitry protects the vehicle’s main electrical branch from catastrophic failure.

• LED Status Indicator: Provides immediate visual confirmation of the relay state and system health at a glance.

Efficiency & Construction

• Ultra-Low Draw: Consumes just 0.001A in standby mode, ensuring minimal parasitic drain on the battery during vehicle storage.

• Motorsport-Grade Chassis: Housed in a CNC-machined aluminium case for superior heat dissipation and durability.

• Heavy-Duty Terminals: Features copper-plated M6 studs for high-conductivity battery connections and a 6-Way Deutsch Autosport connector for signal and logic wiring.

• Compact & Lightweight: Measuring just 99 x 70 x 28 mm and weighing approximately 115 grams, it is significantly smaller and lighter than traditional mechanical isolators.

Reliable Performance

• Wide Operating Voltage: Compatible with 8V to 30V DC systems.

• Sealing: Rated to IP63 for protection in professional racing environments.
