It has very powerful functions.1. For example, the original battery of an electric vehicle is 48V, which can be boosted to 60V to supply power to the electric vehicle, which can increase the speed and acceleration of the electric vehicle.2. Charge your electric bicycle, (1: For example, if you have an idle 12V or 24V battery, you can use this boost power supply to boost the original battery and charge it, which is equivalent to a power bank for electric vehicles. 2: Input at the same time It can also be connected to solar cells, wind energy, generators and other power sources to boost the voltage and charge the original battery to increase the endurance of the electric vehicle.)3. The battery voltage can be increased to make the electric vehicle run faster. It is recommended not to exceed 10V.4. Solar panel voltage boosting and stabilizing.
Precautions:1. The positive and negative poles of the output cannot be connected reversely or short-circuited.2. If used as a boost drive power supply for electric vehicles, the input voltage must be above 24V. The power of electric vehicles is less than 500W. Because the electric vehicle motor is an inductive load, the current will be very large at the moment of starting and when going uphill. Sufficient power headroom must be left.3. When using batteries, switching power supplies, solar panels, generators, etc. as input sources, the battery protection must be lowered, otherwise the battery and power supply will be damaged.4. When working at full load with high current and power for a long time, pay attention to ventilation and heat dissipation to extend the service life of this power supply.5. The power supply can only step up the voltage, not step down, and cannot power electrical equipment that is lower than the input voltage, such as using a 24V battery to charge a 12V battery, or charging a capacitor. Power IEDs below the input voltage.6. Please do not work at full capacity for a long time. Please leave a 20% margin when working continuously and pay attention to ventilation and heat dissipation.

Common problem:
Q1: How efficiently does the module work? I am using it on a battery and it requires high efficiency. Can I use it?A1: The working efficiency of this module is very high. In our actual test, the highest efficiency can reach 98.1%.
Q2: Does this power module have short circuit protection? Will it burn out if the output is accidentally short-circuited during use?A2: Our module is equipped with short-circuit protection. When the output is short-circuited, the fuse will blow out and you need to replace the fuse to recover. You need to pay attention when using it and try not to short-circuit.
Q3: Does this power module have input reverse polarity protection? Will it burn out if I accidentally connect the input power supply backwards during use?A3: It will not burn out, our module is protected against reverse connection.
Q4: The working voltage of the module is 10-60V, so if I input 12V, can it output 48V?A4: Yes, this module is a boost module.
Q5: Can this module run at 72V10A for a long time?A5: This module is designed to have a power of 1800W and can run at 1500W for a long time (a fan is required for forced cooling). 72V*10A=720W, so it can run for a long time.
Q6: I need a current of about 20A. Can this module work in parallel?A6: When the input power supplies are powered separately, the outputs can be directly connected in parallel to double the power. When the inputs are connected to the same power supply, they cannot be connected in parallel.
Q7: What is the working environment temperature of this module? Can it reach industrial grade?A7: Yes, but when the ambient temperature exceeds 40 degrees, please reduce the power or enhance heat dissipation.
Q8: There is a potentiometer on the module. Will the output voltage suddenly increase due to damage to the potentiometer?A8: No, the module uses a multi-turn precision potentiometer. The adjustment accuracy and reliability are very high. There will be no sudden increase in output voltage, so you can use it with confidence. If necessary, it is recommended to customize a fixed output voltage (bulk shipment is required).
Q9: The module power is 1800W. If the output voltage is 60V, what should the current be?A9: This can be calculated from the formula P=U*I, I=P/U. The output voltage is 60V and the current is 30A. Since the maximum output current of the module is about 22A, the maximum output current is 22A.
Q10: The working voltage of the module is 10-60V, so if I input 12V, can it output 97V and 1800W?A10: No. If you input 12V, you can output 97V, but if you want to output 1800W power, the input voltage must be above 48V.
