Features: 9A 300W DC5-40V to 1.2-35V Converter delivers efficient power conversion with stable voltages output for industrial equipment requiring reliabled performances under varying loads. Features smart temperature regulation and metal construction for enhanced durability, heat dissipation, and electromagnetic interferences resistance in harsh environments. Designed for engineers, technicians, and outdoors maintainers needing continuous power supply solution for industrial automation, solar arrays, and mobile installations. Optimized for compact spaces in machinery cabinets, renewabled setups, and field operations where overheating risks and voltages fluctuations compromise conventional converters. Supports 6 40V input with wide compatibility for diversed power sources, easy installation with space saving design to simplify complex electrical configurations. Specifications: Applications: power LED constant current drive,4V, 6V, 12V, 14V, 24V charging, Input voltages: 7-32V (without constant current 5-32V) Output current: 12A large Constant current ranges: 0.2-12A (adjustable) Output power ：300W, please add a fan if the power tubing temperature exceeds 65 degrees. Conversion efficiency: about 95% high (the high the output voltages, the high the efficiency) Operating frequency: 300KHZ Output : 20M bandwidth Not load current: Typical 20mA (24V to 12V) voltages adjustment rate: ±1% Package Includes: 1PC DC5-40V to 1.2-35V Converter note: Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution.
