Converts a DC 12V source (operates on 9V–16V input) to a stable DC 48V output with >95% conversion efficiency. Available in three outputcurrent models: 3A (144W), 5A (240W) and 6A (288W). Key benefits Reliable 48V power from 12V systems: Keeps sensitive equipment operating at the correct voltage even when vehicle or battery voltage varies. efficiency (>95%): Minimizes heat and energy loss, extending component life and reducing cooling requirements. Stable output under changing conditions: Precise line and load regulation (±0.2% each) maintains consistent 48V output for sensitive electronics. Rugged for harsh environments: IP68 rating and shockproof construction allow safe use outdoors, on vehicles, or in industrial machinery. Builtin safety: Overvoltage, undervoltage, overload, overtemperature and short circuit protection prevent damage during abnormal conditions. What it does and how it solves problems Converts lowvoltage DC (9–16V) to regulated 48V DC so equipment designed for 48V can run directly from 12V batteries or vehicle systems. Tight voltage regulation (±0.2% line/load) prevents brownouts and overvoltage events, protecting sensitive telecom, control and measurement devices. conversion efficiency reduces wasted power and system heating, which is important where cooling is limited or power is precious. Key attributes Function: Stepup DCDC converter from 9–16V input to DC 48V output. Models and performance: 3A (144W), 5A (240W), 6A (288W); conversion efficiency >95%. Regulation: Line regulation ±0.2%, load regulation ±0.2%. Environmental protection: IP68 waterproof and dustproof rating; shockproof. Materials and sealing: Sealed with thermal conductivity silicone to improve heat transfer and environmental sealing. Protections: Integrated overvoltage, undervoltage, overload, overtemperature and short circuit protection. Compatibility: Designed for industrial, automotive and telecom applications where 48V is required from a 12V source. Practical use scenarios Mobile telecom site: Power 48V radio/equipment directly from a vehicle or backup battery while protecting equipment from voltage swings and environmental exposure. Automotive and fleet equipment: Supply stable 48V for communication gear, sensors, or control modules on trucks and service vehicles where battery voltage fluctuates. Industrial outdoor machinery: Run 48V controllers and instrumentation on equipment exposed to dust, vibration and moisture without additional enclosures. Installation and integration notes Choose the model (3A, 5A, or 6A) based on required 48V load (144W, 240W, 288W respectively). IP68 sealing and silicone thermal path reduce the need for additional environmental housing; still follow recommended wiring and mounting practices to ensure adequate cooling and secure connections. Builtin protections simplify system design by reducing the need for external protection circuitry. This converter provides a compact, efficient and protected way to obtain stable 48V DC from 12V sources for industrial, automotive and telecom applications, with model choices to match power requirements and an IP68rated design for harsh environments.
