What this product is DC-DC converter that accepts 9 V to 28 V input and provides a stable 30 V output at up to 5 A. Why you need it Converts widely available DC sources into a reliable 30 V supply so your 30 V equipment runs correctly from batteries, vehicle systems, or other DC supplies. High conversion efficiency (>96%) keeps losses low, reducing heat and extending runtime when running from limited power sources. Key features and benefits Function and performance: Constant 30 V output at 5 A for consistent operation of sensitive electronics and loads. Wide compatibility: Works from any 9–28 V DC source, including 12 V and 24 V vehicle systems and many battery packs. Compact, portable size: Measures 5 x 63.4 x 21 mm and includes an 8.1 cm DC cable for easy placement and quick connection in confined spaces. Durable construction: Aluminum housing with IP68 waterproof rating protects the unit in wet, dusty, or otherwise harsh environments. Reliable power delivery: >96% conversion efficiency ensures stable voltage with minimal wasted energy. Practical applications Automotive and marine electronics: Power 30 V sensors, control modules, or instrumentation from 12 V or 24 V vehicle or boat electrical systems while maintaining stable output and resisting moisture. Portable test equipment and field tools: Use as a compact supply for bench or field devices that require 30 V and up to 5 A, benefiting from low heat generation and small footprint. Industrial and outdoor installations: Provide a protected 30 V feed to controllers, actuators, or LED loads where space is limited and environmental sealing (IP68) is required. Installation and use notes Connect to any DC source within 9–28 V; unit will deliver a constant 30 V output up to 5 A. Compact dimensions and short integrated cable simplify mounting in tight enclosures or mobile setups. Aluminum housing offers mechanical strength and environmental protection; suitable for challenging conditions as long as installation follows standard safety practices.
