Protect 24V Alternators from Voltage Surges and Load Dump Damage

Developed for 24V charging systems, this alternator shield helps protect high-output alternators from damaging voltage spikes caused by battery disconnects, load dump events, and lithium battery BMS shutdowns. It clamps excess voltage and safely diverts it to ground, reducing the risk of diode failure and helping maintain the reliability of marine, commercial, and heavy-duty electrical systems.

Key Features

• Optimised for 24V Charging Systems – Provides alternator protection with a 30V to 90V operating protection range, making it suitable for 24V electrical installations.
• Protection Against Voltage Spikes – Helps prevent alternator damage resulting from battery disconnects, load dump events, and sudden over-voltage conditions that can damage internal components.
• Supports Lithium Battery Installations – Reduces the impact of voltage spikes associated with battery management system (BMS) shutdowns in modern lithium battery systems.
• Helps Extend Alternator Life – Minimises electrical stress on alternator diodes and internal circuitry, contributing to improved long-term reliability.
• Integrated LED Status Indicator – Features a built-in LED that provides an immediate visual indication of the shield's operating condition.
• Straightforward Installation – Mounts directly to the alternator terminals for quick integration into existing charging systems.
• Engineered for High-Output Alternators – Built to support modern high-amperage alternators used in demanding marine, commercial, and industrial applications.
• IP68 Waterproof Rating – Sealed against water and environmental contaminants, making it suitable for harsh operating conditions.

Installing dedicated voltage protection helps reduce the risk of costly alternator failures while improving the resilience of 24V charging systems.
