Winners® DC-DC Step Down Power Supply Adjustable Module With LCD Display With Housing Case

Specifications: Converter
type: DC-DC
Input voltage: 5-23V, please keep the margin, it is recommended to use within 20V.
Output voltage: 0V-18V continuously adjustable, automatically save the last set voltage (the input voltage must be higher than the output voltage by more than 1V).
Output current: Maximum 3A, it is recommended to use within 2A. If the heat is large, please solve the heat dissipation problem yourself.
Input anti-reverse: there is
Short circuit protection: none (do not short circuit)
Accuracy: 0.01V, 0.01A, three-digit display, current is A.
Conversion efficiency: up to 95% (efficiency is related to input, output voltage, current, voltage difference).
Load regulation rate: S (I) ≤ 0.8 %
Voltage regulation rate: S (u) ≤ 0.8 % Dimensions 62 x 44 x 18mm
LCD size: 37.5 mm x 17.0 mm (LxW)
LCD accuracy: 1%
Weight: 45g
Calibration method: Under power off situation, Holdind left button and power the supply, when the  display begin flashing, release left button, with multimeter measuring the output voltage, by press the left and right button, adjust the multimeter measuring voltage near 5V, such as 5.00V, 4.98V or 5.02V is ok too, at this situation, please ignore the displaying on this item. After adjustment, please power off it and then power to it again, then the  calibration is completed. Errors can be calibrated in 0.04V, if the error is greater, you can try to calibrate it again.
Package included: 1 x DC-DC step-down power suppl module 1 x Transparent shell,,,,,,,,
