Features Aluminum Alloy Material The metal part of the automatic lift pressure module is made of aluminum alloy, which has good hardness and also good rust resistance. REAL TIME DISPLAY The MPPT control voltage of the auto lift module is displayed at a glance in real time on the LCD screen. Wide Application The car boost module is used in a variety of applications, solar charging, battery lithium charging, LED constant current driver, voltage regulator. Fast Heat Dissipation The chip inside the auto lift module strengthens heat dissipation, reliable and stable, and has high performance. Adjustable: automatic lifting module, all use a screwdriver-free potentiometer, can be adjusted directly manually, very convenient. Specification: Element Type: Boost Buck Power Supply Module Material: aluminium alloy, PCB. Input Voltage Range: DC7-80V Output Voltage Range: DC1.4-79V Voltage display range: 1.40-80.00V (accuracy about ±0.1V) Output Current Setting Range: 0-20A Current display range: 0.00A-20.00A (accuracy ±0.03A or so) Adjustment knob: adjust the MPPT voltage, adjust the output voltage, adjust the output current limit MPPT function: yes. Backflow prevention function: yes, connect battery without string diode Constant current (current limit): yes. LCD display: yes. Over current protection: 300W, if the power is exceeded, the output will be turned off, OPP indicated. Product size: approx. 108 x 64 x 48 mm / 4.3 x 2.5 x 1.9 inches. Applications: solar charging, lithium battery charging, LED constant current drive, voltage regulator Charging: Connect the battery to charge (be careful not to connect the negative pole anyway). MPPT can be adjusted correctly via the potentiometer so that the module is always output at the maximum power point. It is recommended to connect diodes to completely prevent backflow.
