Technical Detail
Frequently Asked Questions
Q: Can this module charge a 24V battery from a 12V vehicle system?
A: Yes, it is specifically designed to step up voltage from a 12V battery or generator (11-16V range) to charge 24V LiFePO4 battery banks.
Q: Is the unit waterproof for outdoor or marine use?
A: Yes, it features an IP68 rating, making it completely dustproof and waterproof, as well as shockproof for harsh environments.
Q: What happens if the input voltage drops too low?
A: The module has under-voltage protection. It will automatically shut down when the input drops to 13V and restart when it reaches 13.5V to protect your source battery.
Q: Does the output voltage stay constant?
A: During the final charging stage, the module provides a constant voltage of 29.2V to ensure the LiFePO4 battery is fully and safely charged.
Q: What is the maximum operating temperature?
A: The module is designed to operate reliably in extreme conditions ranging from -35°C up to +80°C.
Q: Is this an isolated or non-isolated module?
A: This is a DC-DC non-isolated power module, offering high efficiency and 100% full power stability.
