48V to 5V DC DC Converter Step Down Voltage Regulator IP67 Waterproof Efficiency 2A

Compact, efficiency DC to DC stepdown converter for converting 36 V or 48 V systems to a stable 5 V output. Nonisolated design, IP67 waterproof rating, and multiple housing options let you match performance and size to the application. Key benefits Stable 5 V output for powering electronics from 36 V or 48 V sources. Ideal for vehicle and battery systems. conversion efficiency of more than 93 percent reduces heat and improves battery runtime. Waterproof IP67 housing enables reliable outdoor and mobile use. Wide input range of 20 V to 60 V supports varied system voltages and tolerances. Compact form factors and multiple current ratings from 1 A to 33 A simplify installation in tight spaces. Technical specifications Module type: Nonisolated DC to DC buck converter Nominal input voltages: 36 V or 48 V Input voltage range: DC 20 V to 60 V Output voltage: DC 5 V Output current: 1 to 33 A (model dependent) Output power: 5 W to 165 W Conversion efficiency: more than 93 percent Ripple at full load: 40 mV Noload current: 25 mA Cable length: 13 to 14 cm Operating temperature: 40 to 80 C. If ambient temperature exceeds 40 C, reduce load or improve heat dissipation. Waterproof rating: IP67 Nonisolated: input and output share common reference; verify system compatibility before installation Available housings, sizes, and weights ABS Plastic M (1 to 2 A): 46 x 32 x 18 mm, 50 g per unit ABS Plastic L (3 to 5 A): 58 x 40.5 x 22 mm, 97 g per unit Aluminum L (8 to 20 A): 74 x 74 x 32 mm, 260 g per unit Aluminum XL (25 to 33 A): 100 x 80 x 39 mm, 500 g per unit Practical applications Electric bicycles and scooters: step down battery pack voltage to power controllers, lights, and USB devices. Mobile and off grid systems: provide stable 5 V to sensors, GPS units, and communication equipment in outdoor enclosures. Industrial equipment and vehicles: power 5 V control electronics from 36 V or 48 V onboard supplies. Installation and usage notes Verify that a nonisolated converter is acceptable for your system since input and output share a common ground. Ensure adequate ventilation or heat sinking when operating near the upper current limits, especially if ambient temperature exceeds 40 C. Use the appropriate housing and current rating for expected load to maintain ripple and efficiency specifications. Cable length is approximately 13 to 14 cm from the module; plan mounting and wiring accordingly. This converter provides a robust, efficient solution for converting highervoltage DC sources to a reliable 5 V supply across a range of currents and mounting options.
