DC-DC Converter, Asixx 1pc DC-DC Converter Voltage Regulator Step Down Module 5A 4.0V~38V to 1.25V~36V Adjustable

• This is a high efficiency 5A low wave high efficiency DC module and converts 4.0V ~ 38V to 1.25V ~ 36V
• On board voltmeter can be self-calibrated; using a more advanced voltage microprocessor, the error of the voltmeter is ±0.05V, measuring range of 0~40V
• The input and output are equipped with screw terminals for a comfortable connection even without soldering irons and keep the soldering bracket for connecting to the soldering
• Supports overheat protection and short circuit protection function
• Comes with heat sink for better heat dissipation and different spacers and nuts

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
