Feature
●High efficiency: this is a 5 A high-performance DC/DC buck module with low ripple, which converts 4.0 V ~ 38 V into 1.25 V ~ 36 V 0-40 V. The voltmeter on board can be calibrated yourself. When using an advanced voltage microprocessor, the voltmeter is ±0,05 V and the measuring range 0 to 40 V
●Soldering connection: input and output have screw terminals for convenient connection, even without soldering iron, and store the soldering surface for the soldering connection. Multi-protection: supports overheating protection and short circuit protection function
●Max. output power: 75 W max. efficiency: 96% (efficiency in terms of input/output voltage, current and voltage difference) load control S (I): 0.8% voltage regulation S (u): 0.8% size: 60 × 36 × 18 mm / 2.36 × 1.41 × 0.6 inches. 7 "
●Better heat dissipation: comes with a heat sink for better heat dissipation as well as several spacers and nuts
●Technical data: input voltage: 4.0 V ~ 38 V (input voltage should be at least 1.5 V higher than the output voltage). Output voltage: 1.25 V ~ 36 V (infinitely adjustable). Output current: max. 5 A (maximum 4.5 A recommended)

Voltmeter self-calibration instructions:
1. When the built-in voltmeter shows the output voltage, press and hold the right button for 2 seconds to enter output voltage control mode, and the display of the voltmeter and the output voltage indicator flash synchronously. When the built-in voltmeter shows the input voltage, press and hold the right button for 2 seconds to enter input voltage control mode, and the display of the voltmeter and indicator light flash synchronously.
2. Press the right button to increase the voltage value and the left button to reduce the voltage value. Due to the voltage unit of less than 0.1V, you need to press the button 1 time ~ 5 times to see how the voltage value changes by 0.1V.
3. After you have set the voltage, press and hold the right button for 2 seconds and then release it to exit the voltage calibration mode. All configured parameters are automatically saved in the event of a power failure.
