Aideepen | 300W Adjustable Step-Down Module DC17-100V to 3-50V Output 20A High Current Constant Voltage Current for Industrial Equipment

Features:1. Ultra-wide voltage range: 17–100 V input, 3–50 V adjustable output; compatible with various systems ranging from 12 V to 72 V2. 20 A continuous high-current output, easily powers high-power motors, LED strip lights, or industrial equipment3. Constant voltage and constant current, specifically designed for applications requiring current limiting, such as battery charging and LED drivers4. Utilizes synchronous rectification technology, achieving conversion efficiency of over 95%, with effective heat dissipation via the heat sink5. Built-in input under-voltage protection, reverse connection protection, and output short-circuit protection ensure long-term durabilityProduct DescriptionEquipped with original chips and high-performance, high-current MOSFETs, this module achieves high power output in a compact form factor. It supports constant voltage and constant current output with adjustable output voltage. With a maximum input of 100V, it can deliver a high current of 20A at 3–15V and 300W of power at 15V or higher; the load must meet both criteria of less than 20A and less than 300W. The module features multiple protection mechanisms to meet the demands of various high-voltage, high-current applications.Suitable for a wide range of fields, including industrial control systems, communications and network power supplies, power converters, and portable mobile devices.Product SpecificationsInput Voltage: DC 17–100 VOutput Current: 20 AOutput Voltage: Adjustable DC 3–50VQuiescent Current: 3mAConversion Efficiency: 95%Supports constant voltage and constant current outputInput reverse connection protectionInput undervoltage and output short-circuit protectionInput and output equipped with TVS diodesModule InterfacesVIN+: DC input positive terminal 17V–100V (input voltage must be 3V higher than the output voltage)VIN-: DC input negative terminalOUT+: DC output positive terminalOUT-: DC output negative terminal (Note: Connecting VIN- and OUT- may cause inaccurate or failed current detection)Precautions1. Maximum input: 100V; maximum output: 20A (power must be within 300W). Note that operating at full current will generate significant heat; it is recommended to allow for some margin during use.2. It is best to disconnect the power supply when wiring; otherwise, sparks may occur at high voltages, posing a risk of damaging the chip.3. Do not use wires that are too thin; ensure the wires can handle the corresponding current.4. Provide proper protection for inductive loads to prevent excessive back-EMF from exceeding the chip’s tolerance range.5. The higher the power drawn by the module and the closer the current is to the maximum current rating, the greater the heat generation will be. Ensure adequate heat dissipation during use.6. Without external cooling, continuous current should be kept below 15A. Current exceeding 15A requires additional cooling to prevent overheat protection from tripping and to avoid shortening the module’s service life.7. The operating voltage should be kept below 90V. If the supply voltage is unstable, voltage spikes exceeding 100V may trigger the chip’s internal overvoltage protection. To ensure stable operation, allow for an appropriate margin.Package ContentsBuck Module *1
