SMAKN Dc-dc Synchronous Rectifier Buck Power Converter Voltmeter Input 4.5-24v to Output 0.93v-20v(Green)

Dimensions: 44 *30 *20.5mm
Button switch: To switch the display voltage of the voltmeter
Display color: Blue/Red/Green
Input voltage: 4.5-24V
Output power: 20W maximum
Output voltage: 0.93v-20v (step-down mode, The input voltage must be a minimum of 2v)
Output current: Continuous output 2A
Ripple frequency: About 330KHZ
Voltage meter accuracy: ±(5 ‰ +1 digit)
Ripple peak to peak value 30mv
Static power consumption: Typical about 25mA(Color digital tube and the input voltage affect the static current)

Function
Output voltage mode:Boot default display it, LED indicator off
Input voltage mode:Press button switch to it , LED indicator on
Professional data measurement:(For professional enthusiasts reference)
No-load ripple measurement: 30 mv peak to peak value
Loaded with ripple measurement: 30 mv peak to peak value (it is much better than the ordinary lm2596 step-down module with 100 mv peak to paak value indicators)
Load regulation measures:
No load output voltage: 9.0810 V
Full load output voltage: 9.0623 V. Full load, the output of the voltage drop of 0.0187 V (hardly budged)
he efficiency test:(Synchronous rectification scheme ensures the module overall high work efficiency, and its efficiency is much higher than lm2596 schemes typically 85% of the work efficiency)
12v to 5v efficiency measurement: efficiency = 90%
15v to 9v efficiency measurement: efficiency = 93%
20v to 12v efficiency measurement: efficiency = 95%
Note:in the same current output voltage is higher, the higher the efficiency. The actual efficiency and closely related to the input voltage, output voltage, output current. The above represents only 2 A output characteristics. (any instrument error of the above data is for reference only)
