Ecumaster Battery Isolator Rev2 M8 Ring Terminal Autosport

Ecumaster Battery Isolator Rev2 - M8 Ring Terminal Autosport

The Ecumaster Battery Isolator Rev2 Autosport is the definitive solid-state master relay for professional motorsport. Engineered to exceed FIA and Motorsport UK safety regulations, this ultra-lightweight (83g) device replaces unreliable mechanical kill switches with a high-performance, vibration-proof electronic solution. This specific Autosport version is upgraded with a genuine Deutsch ASX series connector, providing a military-grade interface for signal wiring in the most demanding environments.

Equipped with heavy-duty M8 Nickel-Plated Ring Terminals, this isolator ensures maximum conductivity and a high-torque mechanical connection for primary power cables. With a continuous current rating of 300A (and 1000A peak), it is designed to manage the electrical loads of high-compression engines and complex racing electronics while offering built-in alternator load dump protection to prevent catastrophic voltage spikes during emergency shutdowns.

Technical Authority & Key Features

• Solid-State Architecture: Zero moving parts ensures total reliability under extreme vibration and G-forces.

• Deutsch ASX Connector: Features a high-density Deutsch ASX202-06PN signal connector (mating plug included) for superior environmental sealing compared to the standard Club version.

• CAN BUS Configurable: Fully programmable via CAN BUS, allowing for integration with Ecumaster PMU16 units for automatic shutdown upon impact or other logic-driven events.

• Integrated Load Dump: Safely dissipates alternator energy during a "kill" event without the need for external resistors or complex wiring.

• Advanced Diagnostics: Sends real-time data over CAN, including current draw (±10% accuracy), battery voltage, and internal temperature.

• Multi-Colour LED Status: Bicolour LED provides instant visual feedback for states such as Overheat (80°C), Overvoltage (>19V), and Power Save mode.

• Ultra-Low Draw: Consumes less than 1mA in power-save mode, preserving battery life during vehicle storage or between race heats.
