Step Down Module, Fydun 1pc DC-DC Converter Voltage Regulator Step Down Module 5A 4.0V~38V to 1.25V~36V Adjustable With Heatsink Standoffs and Nuts

• Voltage Conversion: This is a 5A high-power high-efficiency DC-DC step-down module with low ripple, which can convert 4.0V~38V to 1.25V~36V.
• Self-calibration: The voltmeter on the board can be self-calibrated; using a more advanced voltage microprocessor, the voltmeter error is ±0.05V, and the measurement range is 0~40V.
• Easy to connect: The interface design is user-friendly, and the input and output have screw terminals, which can be easily connected even without a soldering iron, and the pads for soldering are reserved. Very well connected for your convenience.
• It supports overheat and short circuit With heat sink for better heat dissipation and multiple brackets and nuts. Keep your use safe.
• 【Service】We are responsible for the product and believe in the quality of the product. You can buy with confidence. If you encounter any problems, please feel to contact us, we will reply you as soon as possible after receiving your message.

Specifications: Input Voltage: 4.0V~38V (input voltage should be at least 1.5V higher than the output voltage) Output Voltage: 1.25V~36V (continuously adjustable) Output Current: Max. 5A(4.5A or less is suggested) Max. Output Power: 75W Max. Efficiency: 96% (Efficiency is related to input/output voltage, current and voltage difference) Load Regulation S(I): ≤0.8% Voltage Regulation S(u): ≤0.8% Size: 60*36*18mm/2.36*1.41*0.7" Voltmeter Self-calibration Instruction: 1. When the voltmeter on board displays output voltage, press and hold the right button for 2 seconds to enter output voltage regulation mode, and the voltmeter display and output voltage indicator light synchronously flash.Similarly, when the voltmeter on board displays input voltage, press and hold the right button for 2 seconds to enter input voltage regulation mode, and the voltmeter display and input voltage indicator light synchronously flash. 2. Press the right button to increase voltage value, and left button to reduce voltage value.Due to a unit of voltage is less than 0.1 V, so you need to press button for 1 time~5 times to see the voltage value changes 0.1V. 3. After voltage adjustment, press and hold the right button for 2 seconds then release to exit voltage calibration mode. All the parameters set up will be automatically saved if power failure. Note: To ensure that the voltage meter accuracy, please make sure that the input voltage is above 4.5V Package Includes: 1 x Step Down Module 1 x Heatsink 4 x Standoffs and Nuts
