Battery Isolator AS-SR Radlok Rev.2

AS-SR Radlok Rev.2 Battery Isolator

The Ecumaster AS-SR Radlok Rev.2 Battery Isolator is a motorsport master relay designed for FIA-compliant battery isolation and engine shutdown. Engineered for demanding racing environments, it features an all solid-state design with no mechanical components, ensuring a long lifespan and high reliability. The device weighs only 83g.

The isolator includes integrated alternator overvoltage protection without requiring external components, eliminating the risk of damage to expensive electronic equipment during an emergency shutdown. It is controlled by two external switches and can also be shut off via a CAN-bus message, which can be sent from an Ecumaster PMU16 unit in the event of an impact or other incident. The device is configurable via CAN-bus and transmits diagnostic information that can be used by other equipment, facilitating setup and troubleshooting. It is fully protected against overheating and overcurrent. The device status is indicated by a multicolor LED.
