Product Introduction

1. Using wing shaped heat dissipation has excellent heat dissipation effect and a larger output power (the power can reach around 1800W when 48V input and fan are added).

2. Temperature controlled fan, combined with hydraulic bearing fan, achieves a very good balance in noise and heat dissipation. When the load is light, the fan does not rotate. When the load is heavy and the temperature reaches around 60 degrees, the fan automatically turns on. It can effectively reduce noise and extend lifespan.

3. The insulation board of the main power tube is made of high-grade aluminum oxide, with a thermal conductivity 10 times that of ordinary insulation pads.

4. Using 100V 210A TO-247 large package power transistor, with large power margin and good dynamic response.

5. Double large-sized iron silicon aluminum magnetic rings, using four 1.2-purity copper enameled wires in parallel, with low heat generation and high efficiency.

6. Multi turn potentiometer with high adjustment accuracy and small drift.

7. Kang copper wire output current sampling, constant current stability, and small temperature drift.

8. The undervoltage protection is adjustable, which can effectively protect various batteries and can also be used for solar cells.

9. Equipped with constant current function, it can be used for boosting the voltage of electric scooters, charging batteries, and so on.

10. Input three 20A fuses in parallel to protect against the risk of accidental short circuits in the output.

11. Three indicator lights: undervoltage, overcurrent, power indicator, and clear working status at a glance.

12. Both input and output use high-frequency capacitors, with low output ripple, low heat generation, and long lifespan.

13. MLCC ceramic capacitors have been added to the input and output, resulting in a significant reduction in output ripple, which is approximately 100 millivolts at 48V to 72V 4A.

Output power:=input voltage * 30A,

For example, if 12V * 30A=360W is input, the maximum power when 12V is input is 360W

=Input voltage * 30A

For example: Input 24V * 30A=720W, that is, the maximum power when inputting 24V is 720W

Power Description:

Due to the maximum input current of 30A at 10-30V and 25A at 31-60V for this power supply, the output power is dependent on the input voltage. The higher the input voltage, the greater the power. (Input voltage * input current equals the overall power of the machine) For example, if the input voltage is 12V * 30A, the power is 360W. If the input voltage is 36V, the maximum input current is 25A. The maximum power of the power supply is 900W

Application scope:

We are designed for lead-acid batteries, lithium batteries, solar cells, or power sources to boost and charge electric vehicles, with very powerful functions.

1. For example, the original battery of an electric vehicle can be boosted from 48V to 60V to supply power to the electric vehicle, which can improve its speed and acceleration.

2. To charge your electric bike, (1) For example, if you have a 12V or 24 idle battery in your hand, you can use this boost power to charge the original battery, which is like a power bank for an electric vehicle. (2) At the same time, you can also connect solar cells, wind energy, generators, and other power sources to boost the original battery and increase the electric vehicle's endurance

3. You can increase the battery voltage to make the electric vehicle run faster, and the voltage should not exceed 10V.

4. Boost and stabilize the voltage of solar panels.

Notes:

1. The positive and negative poles of the output cannot be reversed or short circuited.

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 high at the moment of starting and when going uphill. Sufficient power margin must be left.

When using batteries, switch mode power supplies, solar panels, generators, etc. as input sources, the battery protection must be lowered, otherwise it will damage the battery and power supply.

4. When working at high current and full load for a long time, attention should be paid to ventilation and heat dissipation to extend the service life of this power supply.

5. The power supply can only increase voltage and cannot decrease voltage. It cannot supply power to electrical equipment below the input voltage, such as charging a 12V battery with a 24V battery or charging a capacitor. Power lED below input voltage.

6. Please do not work at full load for a long time. When working continuously, please leave a 20% margin and pay attention to ventilation and heat dissipation.

Instructions for use:

Voltage regulation:

When the power is turned on and unloaded, use a flat screwdriver to adjust the output terminal "V-ADJ" potentiometer clockwise to increase and counterclockwise to decrease. Due to the large output capacitor capacity, the response will be slower when adjusting the output voltage from high voltage to low voltage. The amplitude of the instrument adjustment is smaller. (The default output voltage is set to 19V for shipment)

Current regulation:

Turn the "CCA-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the LED battery and other loads, and turn the "CCA-ADJ" potentiometer clockwise to the current you need. For battery charging, after discharging the battery, connect it to the output and adjust the CC A-ADJ to the current you need. When using it for charging, be sure to use the discharged battery for accurate adjustment, because the more remaining battery charge, the lower the charging current. The default output power is set to 3A for shipment. If you need us to adjust the current value properly, please do not use short-circuit output to adjust the current. The circuit structure of the boost module cannot be adjusted by short-circuit

nput low battery protection adjustment:

Low battery protection is mainly aimed at preventing over discharge of the battery when the input power is a battery. If the battery voltage is too low, it can damage the power module and the battery input is a switch mode power supply. Low voltage protection method 1 should also be set, such as setting a 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module and use a flat screwdriver to adjust RV1 (increase the clockwise protection voltage value and decrease the counterclockwise protection voltage value) until the UVLO light is on. At this time, the low battery protection voltage is 10V. When the battery voltage drops to 10V, the power module does not rise (the input voltage is equal to the output voltage). Only when the input voltage is higher than 10V, the power supply will recover and start boosting.

Method 2: Connect the input battery or switch power supply. If the UVLO light on the board is off, turn the RV1 potentiometer counterclockwise to turn on the UVLO light. After turning it on, turn it clockwise twice. If the UVLO light is on, turn the RV1 potentiometer clockwise, turn the UVLO light off, and then turn it two more turns. (Adapted to 8V-45V voltage)
