12V/24V (8-36V) To 5V 3A 15W DC-DC Waterproof Step-Down Converter Module F23J5V3A1S

The F23J5V3A1S is a compact, IP68 waterproof DC-DC converter engineered to deliver regulated 5V power in the harshest environments. Whether you're powering 5V accessories in a vehicle, running LED lighting systems in outdoor installations, or supplying control electronics in industrial automation, this converter transforms your 12V or 24V power source (8-36V range) into a clean, regulated 5V output at up to 3A (15W). Built with synchronous rectification technology for 85.4% efficiency, this ultra-compact unit (2.5" × 1.06" × 0.55") operates reliably from -40°C to +55°C, making it ideal for golf carts, forklifts, automobiles, telecommunications equipment, alternative energy systems, and any application where space is limited but performance cannot be compromised. Every unit undergoes 100% full-load burn-in testing and includes protection against short circuits, overloads, and undervoltage conditions, and RoHS/CE compliance for worldwide deployment.   Specifications Epoxy sealed plastic waterproof housing (IP68) Lightweight, compact, convenient to use and transport Non-isolated Protection: Over-current, over-heating, short-circuit, reverse polarity Auto recovery Input voltage: DC 12V or 24V nominal, will operate on any input voltage from 8V to 36V DC Maximum input current at 3A output: Approximately 1.25A at 12V input, 1A at 15V input Output voltage: 5V Maximum output current: 3A Maximum Output Power: 15W Efficiency: 85.4% typical Voltage regulation: ±3% Load regulation: ± 5% Ripple (Full load test): < 120mVp-p, typically 46mVp-p No-load current: < 10mA Operating temperature: -40C - +55C Size (L x W x H): 46 * 27 * 14 mm / 1.81" x 1.06" x 0.55" (Length including mounting tabs is 63mm / 2.5") Weight: 36g / 1.3oz Waterproof rating: IP68 Input and output wire length: 13.5cm / 5.3" (approx) Package includes 1X 8V-36V Input to 5V Output 3A 15W Waterproof DC-DC Step Down Buck Converter Power Supply Module Installation & Operating Notes As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 3A at 5V (15W), and the input supply is only capable of providing 12V at 1A (12W), the maximum output voltage the converter will deliver is 4V (12W/3A). Wiring Minimum wire size: 22 AWG for input and output For cable runs >50cm (20"): Use thicker gauge wire to minimize voltage drop Best Practice: Place longer wire runs on the input (higher voltage) side Input: Red wire = +V, Black wire = -V (8-36V DC) Output: Yellow wire = +V, Black wire = -V (5V DC) Ensure all connections are secure and properly insulated Thermal Management This converter uses natural convection cooling, therefore, ensure adequate airflow around the unit. Avoid enclosing in sealed boxes without ventilation.  Proper airflow can be verified by measuring the temperature at the middle of the top cover - it should not exceed 80°C during operation.
