12V-60V to 15V-80V DC Boost Power Supply Output Constant Voltage and Constant Current Adjustable Charging Module 100A 2000W                                Feature:      1: Wide range of applications  2: Input current: 100A (maximum)  3: Input power: 2000W (maximum)  4: Simple to use  5: Conversion efficiency: 92-96% (efficiency is related to input and output voltage and current)                Specifications:      1. Product name: High-power non-isolated DC boost module power supply.  2. Product model: 100A2000W.  3. Input voltage: DC12V-60V.  4. Input current: 100A (maximum).  5. Input power: 2000W (maximum).  6. No-load power consumption: less than 2W.  7. Output voltage: DC15V-80V.  8. Output current: 50A (maximum).  9. Output power: 1850W (maximum).  10. Conversion efficiency: 92-96% (efficiency is related to input and output voltage and current).  11. Working temperature: -20~50& 8451;.                Instructions for se:      1. Input + is the positive pole of the power input, and input - is the negative pole of the power input.  2. Output + is the positive output of the power supply, and output - is the negative output of the power supply.  3. When the output of this module requires constant current and current limiting, the ground wires of the input and output must be connected separately and cannot share one wire.  4. Undervoltage adjustable range: DC10.5V-50V (clockwise to decrease, counterclockwise to increase), first adjust the undervoltage adjustable to the minimum, then adjust the input voltage to the required undervoltage protection value, and then counterclockwise Slowly increase the adjustable value, and when the undervoltage indicator light is on, adjust it back one to two circles, and then turn on the power again.          The Undervoltage Protection Function Is Mainly Used for:            (1) Input battery power supply, mainly to protect the battery from being damaged by over-discharge.  (2) Power supply with unstable input voltage, such as solar panels, wind turbines, car generators, etc., to ensure that the power supply and equipment will not be damaged due to low input voltage.  (3) This function also has a certain MPPT function when used on solar panels and wind turbines, which can track the maximum power point when the input power is low to achieve high-efficiency input.  5. Constant voltage adjustable range: DC15-80V (clockwise to decrease, counterclockwise to increase), please adjust the voltage to the required voltage when the output is no-load, and then connect the load (when constant voltage power supply, the constant current should be to the maximum,).  6.
