Cllena DC to DC Converter, Waterproof Power Supply

The input power should be connected from the battery's positive (BAT+) to the converter's positive input (INPUT+), and the battery's negative (BAT-) to the converter's negative input (INPUT-). The output of the converter should then be connected from the positive output (OUTPUT+) to the load's positive terminal (LOAD+), and the negative output (OUTPUT-) to the load's negative terminal (LOAD-).

It is crucial to note the following: * Never connect the converter to a solar panel, PWM/MPPT charge controller, inverter, or wind turbine. * Never attempt to charge the battery using the converter. Ensure proper air convection for cooling. * Never reverse the polarity connections. * Use sufficiently large cables to minimize voltage drop.

The converter is designed for use with 12V or 24V DC battery systems, providing a regulated 5V DC output for various appliances. Its key specifications are:

Input Rated Voltage: 12V/24V DC Input Voltage Range: 10-30V DC Output Voltage: 5V DC Output Rated Current: 20A Output Rated Power: 100W Efficiency: 97% (half load), 95% (full load) Ripple: 200mVp Line Regulation: ±0.2% Load Regulation: ±0.2% Voltage Accuracy: ±1.5% Enclosure Rating: IP68 Operating Temperature: -40°C to 85°C Weight: 288g

The converter features several key benefits: 1. 100% full power and stable current output, with a non-isolated design. 2. Industry-grade DC12V/24V to DC 5V step-down converter, with up to 95% efficiency. 3. Die-cast aluminum shell, epoxy potting, and cooling via free air convection, providing IP68 waterproof and anti-shock protection. 4. Comprehensive protections: Over-current, Over-voltage, Over-temperature, Over-load, and Short-circuit, with auto-recovery when normal operation is restored. 5. Certifications: CE/RoHS, 1-year warranty, and a lifetime of up to 100,000 hours.

When choosing the correct current rating for your loads, consider the following guidelines: * For resistive loads, select a current rating at least 25% higher than the maximum current of the load device (e.g., 10A load requires at least 12.5A converter). * For motor or compressor loads, select a current rating at least twice the maximum current of the load device, as the starting current can be 2-3 times the nominal current.

The converter's input voltage range is 10-30V DC, with a fixed 5V DC output. It can deliver up to 20A of output current, providing a maximum output power of 100W. The high conversion efficiency, multiple protection functions, and robust design make this converter suitable for a wide range of applications, including large trucks, taxi radios, EMU, car audio, LCD TVs, advertising screens, LED strip lights, monitoring systems, motors, and various electronic systems and DIY projects.
