Step-up impulsinis maitinimo šaltinis iki 90V iki 40A iki 1800W

1. With airfoil-type heat dissipation, the heat dissipation effect is very good, and the output power is even greater (the power of the 48V input and fan can reach around 1800W).
2. Temperature-controlled fans, with hydraulic bearing fans, have a very good balance between noise and heat dissipation. When the load is light, the fan does not rotate. After the temperature of the load reaches approximately 60 degrees, the fan automatically turns. Can effectively reduce noise and extend life.
3. The main power tube insulation board is made of high-grade alumina, and the thermal conductivity is 10 times that of ordinary insulation mats.
4. The 100V 210A TO-247 large package power tube has large power margin and good dynamic response.
5. Double large-size ferro-silica-aluminum magnetic rings, using four 1.2-pure copper enameled wires, with low heat generation and high efficiency.
6. With a new design, the conversion efficiency is as high as 98.1% (see the datasheet efficiency conversion curve below for details).
7. Brand 3296W multi-turn potentiometer, high adjustment accuracy, small drift.
8. Kang copper output current sampling, constant temperature and stable temperature drift small.
9. Undervoltage protection is adjustable, which can effectively protect a variety of batteries, and can also be used for solar cells.
10. With constant current function, it can be used for boosting the battery car, charging the battery and so on.
11. The input of 3 20A fuses in parallel can protect the risk of accidental short circuit in the output.
12. Three indicator lights: Undervoltage, overcurrent, power indication, working status at a glance.
13. The input and output are all high-frequency capacitors, low output ripple, low heat generation, and long life.
14. The MLCC ceramic capacitor is added to the input and output, and the output ripple is significantly reduced, which is about 100mV at 48V to 72V 4A.
