1800w 35-40a 30a Dc-dc High Current For Dc Constant Current Power Supply Module

100% brand new and high quality

Features:
With airfoil radiator fins, the heat dissipation effect is very good, and the output power is larger (the power can be up to 1800W when 48V input and fan are added).
Combined with the hydraulic bearing fan, the temperature-controlled fan achieves a very good balance between noise and heat dissipation. When the load is light, the fan does not rotate, and the fan automatically turns on after the load weight reaches 60 degrees, which can effectively reduce noise and extend life.
The insulation board of the main power tube is made of high-grade alumina, and the thermal conductivity is 10 times that of ordinary insulation pads.
Adopting 100V 210A TO-247 power tube, it has large power margin and good dynamic response.
Double large size iron-silicon-aluminum ring, wired by four 1.2 brass lines, featuring low heat and high efficiency.
The new design has a conversion efficiency of up to 98.1% (See the data sheet efficiency conversion curve below for details).
The 3296W multi-turn potentiometer has high adjustment precision and small drift.
The output current of the constantan copper wire is sampled, and the constant current is stable and the temperature is small.
The undervoltage protection is adjustable, which can effectively protects various batteries and can also be used for solar cells.
With constant current function, it can be used for battery car boost, battery charging and so on.
With 3 20A fuses in parallel to protect against the risks of an unexpected short circuit on the output.
Three indicators: undervoltage, overcurrent, power indication, you can get the working status immediately.
Both input and output use high frequency capacitors, low output ripple, low heat generation and long life.
The input and output have newly added MLCC ceramic capacitors, and the output ripple is significantly reduced. It is about 100 millivolts at 48V to 72V 4A.
It is designed for lead-acid batteries, lithium batteries, solar cells or power supply boosting for electric vehicle. It is very powerful.
