Feature 1Fast Heat Dissipation: The chip inside the auto lift module strengthens heat dissipation, reliable and stable, and high power. 2Adjustable: Automatic lifting module all use screwdriver free potentiometer, can be directly manually adjusted, very convenient. 3Aluminum Alloy Material: The metal part of the automatic lifting pressure module is made of aluminum alloy, which has good hardness and also good rust resistance. 4Real Time Display: The MPPT regulation voltage of the auto-lift module is displayed in real time on the LCD screen at a glance. 5Wide Application: Auto boost module is used in a wide range of applications, solar charging, battery lithium charging, LED constant current driver, voltage regulator.SpecificationItem Type: Boost Buck Power Supply ModuleMaterial: Aluminum alloy, PCBInput Voltage Range: DC7-80VOutput Voltage Range: DC1.4-79VVoltage Display Range: 1.40-80.00V (accuracy 0.1V or so)Output Current Adjustment Range: 0-20ACurrent Display Range: 0.00A-20.00A (Accuracy 0.03A or so)Adjustment Knob: MPPT voltage adjustment, output voltage adjustment, output current limit adjustmentMPPT Function: YesBackflow Prevention Function: Yes, connect the battery without string diodeConstant Current (current limiting): YesLCD Display: YesOver Power Protection: 300W, beyond the power will shut down the output, display OPPProduct Size: Approx. 108 x 64 x 48mm / 4.3 x 2.5 x 1.9inApplications: Solar charging, battery charging of lithium batteries, LED constant current drive, voltage regulatorCharging: Connect the battery for charging (be careful not to connect the negative terminal anyway). MPPT can be properly adjusted potentiometer so that the module is always at maximum power point output. It is recommended to connect diodes to completely prevent backflow. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x BoostBuckPowerSupplyModule
