Output power: = input voltage * 30a, e.g. input 12V * 30A = 360W; the power when input 12V is 360W
Input voltage * 30A; for example, input 24V * 30A = 720W, that is, when input 24V, the power is 720W
Power Description:
Since the input current of the power supply is 30A at 10-30V and 25A at 31-60v, the output power is related to the input voltage. The higher the input voltage, the higher the power,
(input voltage * input current is equal to the power of the whole machine). For example, the input power of 12V * 30A is 360W Input 24V * 30A is 720W When the input voltage is 36V, the input current is 25a and the power supply power is 900W
Product features:
1¡£ With the heat dissipation with airfoil, the heat dissipation effect is very good and the output power is greater (the power can be about 1800W when 48V input and fan are added).
2¡£ Temperature control fan, combined with hydraulic bearing fan, has 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 about 60 ¡É, the fan will turn on automatically. It can effectively reduce noise and prolong service life.
3¡£ The insulating plate of the main power tube adopts high-grade alumina, and the thermal conductivity is 10 times that of the ordinary insulating pad.
4¡£ 100V 210a TO-247 large package power tube is adopted, with large power margin and good dynamic response.
5¡£ Double large size iron silicon aluminum magnetic rings, using four 1.2 pure copper enamelled wires, low heating and high efficiency.
6¡£ New design, with conversion efficiency up to 98.1% (see the efficiency conversion curve in the data book below for details).
7¡£ Brand 3296w multi turn potentiometer, high adjustment accuracy and small drift.
8¡£ The output current of constantan wire is sampled, the constant current is stable, and the temperature drift is small.
9¡£ The undervoltage protection is adjustable, which can effectively protect various batteries and can also be used for solar cells.
10¡£ With constant current function, it can be used for battery car boost, battery charging, etc.
11¡£ Input three 20A fuses in parallel, which can protect the risk caused by accidental short circuit of output.
12¡£ Three indicator lights: undervoltage, overcurrent, power indication and working state at a glance.
13¡£ High frequency capacitors are used for input and output, with low output ripple, low heating and long service life.
14¡£ MLCC ceramic capacitor is newly added to the input and output, and the output ripple is significantly reduced, which is about 100 mV when 48V to 72V 4a.
Default delivery: the output voltage is about 19v, the current is about 30, and the undervoltage protection is about 10.5V. If you need to adjust to other voltages, please place an order and contact
It is designed for lead-acid battery, lithium battery, solar battery or power boost to boost the voltage of electric vehicle and charge the battery. It has very powerful functions.
1. For example, the original battery of the electric vehicle is 48V, which can boost the voltage to 60V to power the electric vehicle, which can improve the speed and acceleration of the electric vehicle.
2. Charge your electric bicycle. (first, for example, if you have a 12V or 24 idle battery on your hand, you can boost the voltage through this boost power supply to charge the primary battery, which is equivalent to a charging treasure of an electric vehicle. Second: at the same time, input can also be connected with solar cells, wind energy, generators and other power supplies to boost the primary battery and increase the endurance of the electric vehicle.)
three The battery voltage can be raised to make the electric vehicle run faster. The Jianyi should not exceed 10V.
four Solar panels boost and stabilize voltage.
