Xijia 12V/24V DC to DC Charger, Max 60A Buck-Boost Power Controller, Compatible with LiFePO4, Lead Acid & NMC Batteries, for RVs and Trucks Backup Battery Charging

This product is a 4-terminal synchronous rectification BUCK/BOOST automatic buck-boost DC/DC conversion controller. It supports both BUCK (step-down) and BOOST (step-up) operating modes, making it suitable for applications where the input voltage may be higher, lower, or equal to the output voltage. The controller ensures seamless, low-noise transitions between operating modes. With current-mode control and adjustable input and output voltages, it employs a high-side current sensing method for ground-sharing applications. This makes it an ideal choice for regulators, battery, and supercapacitor chargers in automotive, industrial, telecommunications, and battery-powered systems. 1.

• 1. Unidirectional Charging: The charger isolates the main and auxiliary batteries, allowing power to flow only from the main battery to the auxiliary battery. This prevents reverse charging from the auxiliary battery to the main battery, enhancing overall safety.
• 2. Solar Panel Compatible: Equipped with a built-in MPPT controller, it supports solar panel input to charge the auxiliary battery with a maximum output current of 60A and a conversion efficiency of 98%! Note: The battery and solar panel cannot be used simultaneously.
• 3. Compact and Lightweight: Measuring 7.28 inches in length, 4.72 inches in width, 2.83 inches in height, and weighing only 1.3 kg, this charger is easy to install and carry, making it an excellent space-saving solution.
• 4. Quiet Operation: Equipped with a long-life ball bearing fan, it ensures efficient heat dissipation with minimal noise, operating at less than 30dB, providing a disturbance-free experience for users.
• 5. Contact Us Promptly: Installing and using this device requires a basic understanding of electrical circuits. If you are unfamiliar with its principles, lack basic hands-on skills, or do not understand energy conversion, please purchase with caution. For any questions, feel free to contact the seller's customer service.
