3.5V-30V 6A 100W LTC1871 DC-DC Boost Voltage Meter Dual Digital Display Voltmeter

Features :
 
In+: Input positive
In-: Input negative
Out+: Output positive
Out-: Output negative
weight: 35g
Dimensions: 67 *42 *18mm(length*width* height)
Display color: Blue/Red/Green
Input voltage: 3.5-30V
Output power: 100W maximum{Note: according to the law of conservation of power、 computation under the condition of rated output current
Uin*Iin*efficiency =Uout*Iout (Uin: input voltage、 Iin: input current)}
Output voltage: 3.5v-30v (step-up mode、 the input must be less than or equal to the output voltage)
Input current: 6A(maximum 10A)
Voltage meter accuracy: ± (5 ‰ +1 digit)
Static power consumption: Typical about 15mA(With the input voltage、 output voltage and the color is closely related to the digital pipe. The actual current there is a deviation)

Function: Operating mode description: With key off function、 and reduce power consumption.Input and output voltages can be displayed alternately.Power state can be freely defined.Output voltage mode:Boot default display it、 LED indicator offInput voltage mode:Press button switch to it 、 LED indicator onAlternating mode:Press button again input/output voltage alternately display (3s). Press button again、 switch to output voltage display.



Memory code:

Keep pressing the button between 2s and 4s、 current operating state of the memory module automatically switched on.
0: Represents the default boot display output voltage.
1: Represents the default boot display input voltage.
2: Represents the default boot display power-output-input voltage alternating.



LED voltmeter stop working mode(the mode is still working): Keep pressing the button until the monitor does not display numbers ( long press more than 4s) and release the button. LED lights shuts down. At this time、 it does not perform memory function. Click the button、 the LED voltmeter starts working again. 


Data testing (voltmeter open) :

3.7 V to 5 V / 2 A 82.5% efficiency
5 V to 12 v / 2 A 88.4% efficiency
7.4 V to 12 V / 2 A 90.2% efficiency
12V to 18 v/ 2 A 93.6% efficiency
18V to 24 v / 2 A 95.3% efficiency
24V to 30 v 2 A 97.1% efficiency
 
Conclusion: the higher the input voltage is more efficient. Close the voltmeter booster module will get higher work efficiency.
