This boost constant current module adopts 100V 210A TO-247 large package power tube, large power  redundancy, nice dynamic response. Constantan wire output current sampling, constant current and stable temperature, temperature drift is low. Combined with the temperature controlled fan, it gets a very nice balance of noise and heat dissipation. It is designed for leadacid battery, lithium battery, solar battery or power supplys boost to electric car boost, battery charging and very powerful function.

Features: 
The main power tube insulation board is made of high-grade aluminium oxide material, with 10 times the thermal conductivity of common insulation pads.
Adopt 100V 210A TO-247 large package power tube, large power  redundancy, nice dynamic response.
Double large size -silicon aluminium magnetic rings, using four 1.2 pure enameled wire and rapped, low heat generations, high efficiency.
Multi-turn potentiometer, high adjustment accuracy, small drift.
Constantan wire output current sampling, constant current and stable temperature, temperature drift is low.
With constant current function, can be used for battery car boosting, charging batteries, etc.
Three 20A fuses are connected in parallel to protects the output from accidental short circuit.
Quality filter capacitors are used for the input and output, with low ripple, low heat generations and long lifespan.
The MLCC ceramic capacitor has been added to the input and output, which significantly reduces the output ripple to about 100 mV at 48V to 72V 4A.
Under-voltage protections, over-current protections, can effectively protects all kinds of batteries, also can be used for solar cells.
Three indicators: undervoltage, overcurrent and power indication, the working status is clearly at a glance.
Combined with the temperature controlled fan, it gets a very nice balance of noise and heat dissipation. When the load is light, the fan does not rotate; when the load is heavy, the fan automatically turns on after the temperature reaches about 60 degrees.
The heat dissipation effect is very nice and the output power is higher (48V input with fan can reach about 1800W). It can effectively reduce the noise and extend the working lifespan.
Application ranges:
We are designed for leadacid battery, lithium battery, solar battery or power supplys boost to electric car boost, battery charging and very powerful function.
1、For example, the primary battery of the electric car is 48V can be boosted to 60V to power the electric car, which can improve the speed and acceleration of the electric car.
2, For your electric bike charging, (a: for example, there is a 12.0V or 24 idle battery on hand, you can charging the primary battery through this power supplys after boosting, equivalent to an electric car charging treasure. b: At the same time, the input can also be connected to solar cells, wind energy, generators and other power boost to charges the primary battery to increase the range
