1200W/1500W/1800W 20A/30A/40A DC-DC Boost Converter Step Up Power Supply Module 10-60V to 12-90V Adjustable Voltage Charger

Descriptions:
Module name: 1500W boost constant current module
Module properties: non isolated boost module (BOOST)
Working temperature: -40~+85 degrees 
Working frequency: 150KHz
Conversion efficiency: 92%-97%(efficiency have an effect on input voltage, output voltage,current and pressure difference)
Installation: 4pcs 3mm column
Connection mode: Terminal blocks (please use big current and pure copper wire)
Module size: 130mm x 52mm x 84mm(L x W x H)
Specifications:
Input voltage: 10-60V
Input current: 30A(10-30V input)
25A(31-60V input)
Static operating current: 15mA 
Output voltage: 12-90V continuous adjustable (default output 19V)
Output current: MAX 20A, over 15A please strengthen the cooling (have an effect on input and output, differential pressure, the greater the pressure difference between the input voltage and output voltage, the smaller the current is )
Constant current range: 0.8-20A (+/- 0.3A)
Output power: = input voltage x 30A
Feature:
1.Over current protection: there is a certain range of error in the input over 35A,automatically reducing the output voltage.
2.Short circuit protection: there is (input 30A fuse) double short circuit protection,more secure to use.
3.Input reverse polarity protection: there is (150A MOS tube to avoid this).
When using the boost power supply should pay attention to the following points:
1. the output polarity cannot be reversed or short circuit.
2. when using batteries as the input source, you must lower the battery protection, otherwise it will damage the battery and power supply
3. Input power supply voltage must be above 10V.
4. When the power supply is used for the input power supply, the input power and the output voltage of the input power supply are the first to be unloaded. Then pick up the load. (must ensure that the switching power supply has been working).
5. When the constant current mode is used to set the voltage, the constant voltage must be higher than the input voltage.Do not use the way of short circuit output current,the circuit structure of the boost module can not be adjusted in short circuit way.
6. If the input voltage fluctuation range is lower than the set output voltage,then the output voltage is constant, it is to ensure that input is lower than the output voltage.
