Intelligent under-voltage protection: UVP potentiometer regulates under-voltage protection to prevent power supply overload and damage 4. Constant current load adaptation: CC potentiometer regulates the output current, suitable for constant current loads 5. High-current stability: line open tin window processing and copper resistance detection, to ensure stable operation under high current Parameter： Product Name：1200W 20A Boost Power Module Input voltage: Model A: DC 14-60V Model B: DC 14-85V Model C: DC 14-85V Output voltage: Model A: DC 14-90V (±5V) B: DC 14-120V (±5V), output 120V, input voltage should be more than 20V. Model C: DC 14-90V (±5V) Input current: 20A (Max) Output regulation current: 1.5-20A (±0.5A) Input undervoltage protection range: 10-60V (±5V) Fan open temperature: 40 degrees Input reverse connection protection: Yes Typical efficiency (input and output pressure difference is small efficiency is higher): 90%-96% Dimensions (with fan): 130*52*62mm Attention: 1. 120V output, input voltage should be 20V or more. 2. Input and output voltages try not to use the highest or lowest. 3. The working current can not exceed the maximum input current of the power supply, the working current calculation method: output power divided by the input voltage times 1.06 (1.06 is the loss of power supply). For example: 1200W A model, for example, the input voltage 15V, output 48V, output load current 5A, 48V * 5a/15v * 1.06 = 16.96A, this time the working current is less than 20A, is able to work normally. If the load is 48V 7A, 48V * 7A / 15V * 1.06 = 23.75A, at this time the operating current is greater than the maximum input current of the power supply 20A is not available. 4. on the efficiency: the smaller the difference between the input and output pressures, the higher the efficiency, the lower the efficiency of the pressure difference is large, if the input is 20V, the output is 120V. at this time the efficiency is the lowest, it will be lower than 90% of the following. The power of the input power supply should be greater than the load more than 1.5 times. 5. It is strictly prohibited to output short-circuit current regulation. 6. It is strictly prohibited to charge the super capacitor. 7. The fan is temperature-controlled, the radiator temperature up to about 40 degrees before turning.
