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 . Instructions for use: 1. Input+represents the positive pole of the power input, and input - represents the negative pole of the power input. 2. Output+is the positive pole of the power output, and output - is the negative pole of the power output. 3. When constant current and current limiting are required for the output of this module, the input and output ground wires must be connected separately and cannot share the same wire. 4. Adjustable range of undervoltage: DC10.5V-50V (clockwise to decrease, counterclockwise to increase). Firstly, adjust the undervoltage to the minimum, then adjust the input voltage to the required undervoltage protection value, and then slowly adjust it counterclockwise to increase. When the undervoltage indicator light is turned on, adjust it back one to two turns and power it on again. The undervoltage protection function is mainly used for: (1) Input battery power is mainly used to protect the battery from damage caused by over discharge. (2) Power supply with unstable input voltage, such as solar panels, wind turbines, car generators, etc., ensures that the power supply and equipment are not 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, achieving efficient input. 5. Adjustable range of constant voltage: DC15-80V (clockwise decrease, counterclockwise increase). Please adjust the voltage to the required voltage when outputting no-load before connecting to the load (constant voltage power supply should be adjusted to the maximum constant current). 6. Adjustable range of constant current: 5A-50A (clockwise decrease, counterclockwise increase), first adjust the output voltage to the voltage required by the load without load (the load voltage should be 2-3V higher than the load voltage during constant current), adjust the current to the minimum, and then slowly adjust the current to the current required by the load. 8. This power supply is equipped with an intelligent temperature controlled fan. When the power temperature reaches around 55-60 degrees, the fan automatically turns on, and when the power temperature drops to around 50 degrees, the fan automatically turns off. 9. The input voltage cannot fall below 12V or exceed 60V (please reduce the load appropriately when the input voltage falls below 12V). 10. The maximum input current cannot exceed 100A, and the power cannot exceed 2000W. 11. When using, it is necessary to ensure that the input voltage is at least 2V lower than the output voltage. When using a switching power supply or other secondary power supply, please ensure that the power supply power should be greater than twice the power supply of this module. 13. When protecting the power supply from overcurrent or undervoltage, the output still has a voltage close to the input value, and the protection only means that the power supply does not boost. 14. The output blue indicator light will only light up when the power supply is boosted. 15. Important note: Please try not to use inputs below 12V as much as possible. If the output voltage exceeds 60V with full load, the output power should be appropriately reduced when the input and output pressure difference is large. The larger the pressure difference, the lower the power efficiency and the greater the heat generation. 16. Output load instructions: When inputting 12V (input current 100A, output below 60V, maximum output can carry a load of around 1100W), when inputting 24V or above (maximum input current 85A, maximum output can carry a load of below 1850W), the test load is a resistive load, and other loads depend on the situation. 17. Input current and power instructions: Under no circumstances should the input current exceed 100A. When the input working current exceeds 75A or the input power exceeds 1000W, heat dissipation should be strengthened (by sticking the lower part of the power supply to a metal surface for heat dissipation).
