DC-DC LTC1871 High Power Boost supply Power Mode 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 off
Input voltage mode:Press button switch to it , LED indicator on
Alternating mode:Press button again input/output voltage alternately display (3s). Press button again, switch to output voltage display
Memory mode:
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.
