The company can issue ordinary VAT invoices for more than 200 yuan and collect 6% more tax points.
Statement: 1: Do not understand the basic technical knowledge and basic practical ability of cautious pat, blindly tossed rather not sell, thank you!
2: Normally no stranger calls are answered. If you have any questions, please contact Wangwang. Please describe the use parameters and problem points.
3: In remote areas, please contact the freight differential. Thank you. No direct payment.
4: If there is a problem, the goods can be returned and exchanged, and there is no basic operation and usage parameter problem, it can be guaranteed for one year (except unacknowledged usage parameters).

New version of the picture: Increase the load indicator, the load current is greater than a certain value of the red light, otherwise the green light. It is normal that the load current will flash at the critical point or the load jump lamp. In addition, the function requires the preset value of the output current potentiometer to be greater than 3A.
The thermal resistance of insulating layer of aluminium substrate is adjusted from 1 by increasing the protection value of undervoltage.K/wIncreased to 2_k/w, control the thickness of copper plate to increase to 2oz, overtemperature protection to increase to 95 degrees, and test the load of 200W at 90 degrees temperature.
2 Parallel Version:
Old versions have test parameters to refer to:
Shipment contains M4 screw, large radiator 80*77*16mm, small radiator 80*77*6mm
Notes: Do not try to modify welding parameters, welding should also ensure static problems
The maximum input current is 20A. Do not use it for a long time under the maximum current, especially in the high boost ratio mode.
Input and output positive and negative poles must not be reversed, otherwise they must be burned without free warranty.
Potentiometer life is limited and frequent regulation is not advocated.
Applications: Power tracking charging of solar panels or generators
Voltage stabilized power supply can be adjusted to charge batteries
Application of Input Power Restriction
Battery Charging, Battery Constant Current Discharge, High Power LED
Regulating power supply for equipment
Application of Extended External Control Voltage and Current

Performance improvement recommendations:
There is only one plate electrolytic capacitor. If the load is high-power electrical equipment (except batteries), it is recommended that more input and output electrolytic capacitors be connected in parallel, which can improve the life of the capacitor on the board and reduce the ripple. Capacitance selection is based on the actual voltage higher than (but not too high).![](http://ae01.alicdn.com/kf/HTB1DIA.a16sK1RjSsrbq6xbDXXaK.jpg)
