DCDC Power Module 1500W 30A 12V24V48V to 48V60V72V Constant Voltage Current Power Converter Condition: Item Type: Power ModuleMaterial: Printed Circuit Board 1. Use airfoil heat dissipation, heat dissipation effect is very good, output power is larger (power can reach about 1800W when 48V input is added with fan). 2. Temperature-controlled fan, combined with hydraulic bearing fan, a very good balance between noise and heat dissipation. When load is light, fan does not rotate, and when load temperature reaches about 60 degrees, fan automatically turns on and rotates. Can effectively reduce noise and extend life. 3. Main power tube insulation board is made of high-grade alumina, and thermal conductivity is 10 times that of ordinary insulation pads. 4. Using 100V 210A TO-247 large package power tube, with large power margin and good dynamic response. 5. Double large-size sendust magnetic rings, using 4 of 1.2 pure copper enameled wires, with low heat generation and high efficiency. 6. design, conversion efficiency up to 98.1%. 7.3296W multi-turn potentiometer, with high adjustment accuracy and small drift. 8. Constantan wire output current sampling, constant current and stable temperature drift. 10. With constant current function, can be used to boost battery car, charge batteries, etc. 11. Input 3 of 20A fuses in parallel, can protect risks of accidental output short circuit. 12. Three indicator lights: undervoltage, overcurrent, power supply indication, working status is clear at a glance. 13. Both input and output use high-frequency capacitors, with low output ripple, low heat generation and long life. 14. MLCC ceramic capacitors are newly added to input and output, and output ripple is significantly reduced, about 100 millivolts when 48V turns to 72V 4A. Application: QS-4884CCCV-1800W is designed by us for boosting lead-acid batteries, lithium batteries, solar batteries or power supply to boost electric vehicles and charge batteries. has very powerful functions. 1. For example, original battery of an electric vehicle is 48V, can be boosted to 60V to power electric vehicle, can improve speed and acceleration of electric vehicle. 2. Charge your electric bicycle, (1: For example, if you have a 12V or 24 idle battery in your hand, can use this boost power supply to charge original battery, is equivalent to a power bank for electric vehicles. 2: Simultaneous input can also be connected to solar batteries, wind energy, generators and other power sources to boost original battery to increase endurance of electric vehicles.)
