LTC1871DC-DC Step upAdjustableRegulator Module with Voltage Meter 1. Input voltage range :3.5-30V Note: 30Vmaximum voltage limit must be aggressive in order to avoid accidental damage. 2. Output voltage range :3.5-30V (boostmode, the input must be less than or equal to the output voltage). 3. Input Current: 6A maximum 10A outputpower: 100W. 4. Note: According to the law ofconservation of power output current under nominal conditions. 5. UIN * Iin * efficiency = Uout * Iout(UIN: input voltage Iin: input current). 6. Size: 66mm * 42mm * 18mm Weight: 35 g/ pcs. 7. The voltmeter accuracy: ± (5 % +1word). 8. Static power consumption: Typical 15ma(input voltage output voltage and the digital tube color is closely related tothe actual current deviation). 9. IN +: Input the cathode IN-: Inputnegative OUT +: the output cathode OUT-: Negative output. 10.Reverse Polarity ProtectionFeatures: 1: input and output voltage can be alternatelydisplayed. 2: switched on can be freely defined. 3: with a button to turn off the digitalcontrol function, reduce power consumption. Working mode: Output voltage mode: the default bootdisplay ** output voltage mode. * LED indicator turns off Input voltage mode: press the switch onceto switch to the input voltage mode **. * LED indicator lights Alternating pattern: Once again press theswitch input / output voltage alternating 3S alternately display data (pressagain to return to the display mode of the output voltage) Operation and digital displaydescription: [0] represents the default the bootdisplay output voltage [1] represents the default boot displayinput voltage [2] represents the default open to inputand output voltage are displayed alternately Long press the button more than 2Sdigital tube display more information (in this case the key is released), themodule automatically remembers the current state of the default power-on state. The digital tube close operation: longpress button 4s until the digital tube display the contents of the LED is lit,the display section has been closed. Press the button again to restore thedisplay Data test (voltmeter turned on): 3.7V turn 5V/2A efficiency of 82.5% 5V to 12V/2A efficiency of 88.4% 7.4V turn 12V/2A efficiency of 90.2% 12V switch 18V/2A efficiency of 93.6% 18V switch 24V/2A efficiency of 95.3% 24V turn 30V/2A efficiency of 97.1% Note: The higher the input voltage,the higher the efficiency. Close the voltmeter boost module will get higherefficiency. The input Voltage must be less than or equal to the output voltagePackage Contains1x LTC1871 DC-DC Step up Adjustable Regulator 100 Watt ModuleShipping Time:US, Great Britain, Australia(7-14 business days)Canada, South America, Italy and some other countries(7 - 25 days)Brazil, Israel(5-7 weeks)We ship 5 Days a Week Monday to Friday to ensure the quickest possible order processing.We require 1-2 business days to process and pack items after payment has clearedPlease note delivery times are based on averages in BUSINESS DAYS, not including weekendsInternational Buyers –Please Note:Import duties, taxes, and charges arenot includedin the item price or shipping cost.The buyer is responsible for the import customsclearance and all duties, taxes and other costs in the country of destinationPlease check with your country's customs office to determine what these additional costs will be prior to looking or buyingShipping Methods:We use Air Parcel of India Post to ship items.If you want to change to some other shipping services, such as EMS, DHL or FEDEX, please contact us before placing any orders.
