Features [High Efficiency] This buck module can efficiently and stably convert high input voltage (DC 25 to 90V) to low output voltage (DC 2.5 to 50V), reducing energy loss, improving overall system energy utilization. [Metal Housing] The adjustable buck converter module features a protective metal casing that also acts as a heat sink, ensuring module safety and efficient cooling for optimal performance. [Stable Output] The buck converter module provides a stable output voltage with high reliability, ensuring consistent power supply and protecting connected devices for reliable operation. [Ensure Safety] The buck module effectively guards from overload, overheat, short circuit, etc., ensuring circuit safety and reliability in diverse operating conditions. [Wide Application Range] Ideal for applications where the output voltage is lower than the input voltage, such as power tools (angle grinders, impact drills, wrenches, hammers, electric screwdrivers), electric vehicles, and other buck voltage needs. 1.
