Samlex Protector 40A 12-24V

SAMLEX Protector 40A 12-24V: Ultimate Battery & System Protection

Ensure the longevity and reliability of your entire electrical system with the SAMLEX Protector 40A. Designed for demanding applications in the Electronics and Electrical connections field, this intelligent device is the ultimate safeguard against the two most common causes of battery failure and equipment damage: excessive discharge and over-voltage. By investing in this advanced protector, you prevent costly battery replacements, protect sensitive connected loads, and guarantee that you always have enough power for critical functions like engine starting.

The SAMLEX Protector 40A is an essential component for any 12V or 24V DC system, from recreational vehicles and marine vessels to off-grid solar installations and commercial fleets. Its core function is to intelligently monitor your battery´s voltage. Before the battery is completely drained to a point that could cause permanent damage, the Protector automatically disconnects non-essential loads. This action preserves the battery´s health and ensures sufficient charge remains for vital operations.

Key Benefits:

* Extend Battery Lifespan: By preventing deep discharge cycles, which are a primary cause of premature battery failure, the Protector significantly extends the service life of your expensive lead-acid or lithium batteries.
* Protect Sensitive Electronics: The integrated over-voltage protection instantly disconnects loads if the voltage exceeds a safe threshold , shielding your valuable onboard electronics from irreversible damage.
* Ensure System Reliability: Prioritize power for critical systems. The Protector ensures that non-essential devices don’t drain your battery, giving you the peace of mind that starting power or emergency communications will be available when you need them most.
* Fully Automated Operation: "Set it and forget it" functionality. The microprocessor-controlled unit handles all monitoring and switching automatically, requiring no user intervention during operation.
* Enhanced Efficiency: Engineered with advanced MOSFET technology instead of mechanical relays, it offers extremely low voltage drop and silent operation, ensuring your appliances receive maximum power without energy loss or annoying clicking sounds.

Main Features:

This protector is engineered for superior performance and flexibility. It features automatic system voltage detection, seamlessly adapting its protection parameters for both 12V and 24V systems without manual configuration. It offers multiple, easily selectable programs for disconnect and reconnect voltage thresholds, allowing you to customize the protection level to match your specific battery type and application needs. An ultra-low quiescent current consumption means it draws a negligible amount of power while on standby, preserving your battery’s charge. For enhanced system integration, it includes a dedicated alarm output, perfect for connecting a visual (LED) or audible (buzzer) warning before a disconnect event occurs. Furthermore, a terminal for a remote on/off switch provides convenient external control, allowing you to manually bypass or disable the unit from a dashboard or control panel.
