Feature

●The voltmeter on board can be calibrated by yourself; using advanced voltage microprocessor, voltmeter error is ± 0.05V, measuring range from 0~40V.
●Input and output have screw terminals for convenient connection even without soldering iron and hold soldering pad for solder connection
●This is a 5A high power DC-DC downward module with low ripple and converts 4.0V ~ 38V to 1.25V ~ 36V.
●It supports overheating protection and short circuit protection function
●Comes with heat sink for better heat dissipation and multiple spacers and nuts


Description

Specifications:
Input voltage: 4.0V ~ 38V (input voltage should be at least 1.5V higher than the output voltage)
Output voltage: 1.25 V ~ 36 V (infinitely adjustable).
Output current: max. 5A (4.5A or less is recommended).
Max. Output power: 75 W.
Max. Efficiency: 96% (efficiency refers to input/output voltage, current and voltage difference).
Load rule S (I): ≤ 0.8% voltage regulation S (u): ≤0.8%.
Size: 60 x 36 x 18 mm / 2.36 x 1.41 x 0.7 inches.
Voltmeter self-calibration instructions:
1. When the voltmeter on board shows the output voltage, press and hold the right button for 2 seconds to enter the output voltage control mode, and the voltmeter display and output voltage indicator flash synchronously. When the voltmeter on board shows the input voltage, press and hold the right button for 2 seconds to enter the mode for regulating the input voltage. At the same time, the display of the voltmeter and the display of the input voltage flash synchronously.
2. Press the right button to increase the voltage value, and the left button to reduce the voltage value. Since a voltage unit is less than 0.1V, you need to press the button 1 time ~ 5 times to change the voltage value V.
3. After voltage setting, press and hold the right button for 2 seconds and then release it to end the voltage calibration mode. All set parameters are automatically saved in the event of a power failure.
Note:
To ensure the accuracy of the voltmeter, make sure the input voltage is above 4.5V
Package includes:
1 x downward module.
1 x heat sink.
4 x spacers and nuts.
