This nonisolation DC regulated power converter module provides a robust 12 V output from a wide input range, making it suitable for a variety of vehicle, marine, and industrial applications. Built for reliability, it combines compact packaging with rugged construction and efficient performance. Key benefits and features Wide input to fixed output: accepts 8 V to 40 V DC input and regulates to a stable 12 V DC output, enabling a single module to power 12 V loads from diverse sources. Nonisolation design: straightforward regulation with common ground between input and output, suitable for systems that do not require galvanic isolation. efficiency, low heat: components deliver up to 90% conversion efficiency, helping reduce heat and extend service life in demanding environments. Rugged, compact housing: aluminum alloy enclosure that is small and easy to mount in tight spaces. Water and dust resistance: siliconesealed construction provides IP68 level protection, plus resistance to dust and vibration, for reliable operation in harsh conditions. Long service life: designed for durable operation in challenging environments with consistent performance over time. Material, size and mounting Housing: aluminum alloy for strength and light weight Seal: silicone for an IP68 rated seal Size: compact and easy to integrate into tight installations Mounting: designed for straightforward mounting in a variety of locations and orientations Performance highlights Output: stable 12 V DC Input range: 8–40 V DC Efficiency: up to 90% with components Durability: dust and vibration resistant; IP68 sealed for rugged environments Lifespan: designed for long service life in recurring use scenarios Applications and use scenarios Automotive and commercial vehicles: power 12 V accessories such as GPS units, radios, dash cameras, and other electronics from 12 V or 24 V vehicle electrical systems. Marine and outdoor equipment: supply reliable 12 V power for lighting, navigation instruments, and sensors on boats or outdoor installations where exposure to dust, water, and vibration is common. Industrial and offgrid systems: provide stable 12 V for sensors, monitoring equipment, and DC distribution in remote facilities, RVs, or solar/alternative power setups with input sources in the 8–40 V range. Notes This module is nonisolation type; ensure system design accounts for the shared input/output reference. Suitable for use cases requiring a compact, durable, and efficient 12 V supply from a wide DC input range.
