Common Concerns Answered
What is the current rating for the Blue Sea 7635 m-LVD?
The Blue Sea 7635 m-LVD is rated for 10A continuous current. For high-draw systems, users may consider alternative solutions if this rating is insufficient for their specific load configuration.
Does this unit come with an audible alarm?
The Blue Sea 7635 m-LVD features an alarm output for an audible warning, but an optional alarm module is required for this functionality. This allows users to customize their alert system.
Is this product suitable for complex battery systems?
This m-LVD is specifically designed for single battery systems. For more complex configurations involving multiple battery banks and automatic charging, other Blue Sea Systems products like the ML-ACR might be more appropriate.
Frequently Asked Questions
What is the Blue Sea 7635 m-LVD Low Voltage Disconnect?
The Blue Sea 7635 m-LVD is an automatic device that disconnects electrical loads from a battery when the battery voltage drops to a pre-set low level, preventing over-discharge and ensuring starting power.
How does the m-LVD prevent a dead battery?
It monitors the battery voltage and, upon reaching the designated low voltage threshold, opens the circuit to the connected loads, thereby preserving the remaining battery charge for critical functions like engine starting.
Can the disconnect voltage be adjusted?
Yes, the disconnect voltage threshold can be adjusted using the included Remote Control Switch, offering flexibility to match specific battery types and usage requirements.
What is the override function on the remote control switch?
The override function on the remote control switch allows for temporary reconnection of loads, even if the low voltage threshold has been met, which is useful for specific operational needs.
What is the California Proposition 65 warning for this product?
The California Proposition 65 warning indicates that this product contains chemicals known to the State of California to cause cancer or reproductive toxicity. It is advised to consult the product manual or manufacturer for specific details.
