< class="title"> DC-DC Step-up Boost Converter Constant Current Power Supply Module LED Driver Features: This is a great 1200W DC to DC step-up power supply module for electric equipment, digital products, laptop, etc. Input and output are designed with screw terminals for convenient wire connection and disconnection. High efficiency, the maximum conversion efficiency can be 97% and efficiency is related to input/output voltage, current and voltage difference. There is a big heat sink and cooling fan that would ensure a better heat dissipation. It can also be used as a driver for high power LED lights or voltage regulator for solar panels. Specifications: Type: Non-isolated boost module Input Voltage: DC10V to 60V Max Input Current: 20A (could 25A at 12V-24V when adding cooling fan) Quiescent Current: 15mA(will increase when convert 12V to 20V) Output Voltage: 12V to 83V(continuously adjustable, default 19V) Max Output Current: 18A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 10A) Constant Current Range: 0.5A to 18A(+/-0.3A) Reverse Input Protection: Yes (150A MOS) Lower Voltage Protection: Yes (9V to 50V adjustable) Temperature Control Fan: Yes (Fan starts to work if more than 55) Operating Temperature: -40 to 85(if temperature is too high, please enhance heat dissipation) Frequency: 150KHz Conversion Efficiency: 92% to 97% (Efficiency is related to input/output voltage, current and voltage difference. The smaller difference is, the higher efficiency will be) Input Over-current Protection: Yes (automatically protect when input is more than 25A, and power supply voltage will not increase) Short Circuit Protection: Yes (input 30A fuse) Wiring Method: Terminals (Please use large current copper wire) Size: 130 x 64 x 52mm / 5.12 x 2.52 x 2.04" Voltage Adjustment: Power on module while not connect to load, then adjust "V-ADJ" potentiometer clockwise to increase, counterclockwise to decrease. Due to large output capacitance capacity, response will be slow when adjust high voltage to low voltage. Current Adjustment: Adjust "A-ADJ" potentiometer counterclockwise about 30 circles to minimize the output current before connecting to load. Then adjust "A-ADJ" clockwise to the current value you need.If you use the module for battery charging, connect to output after battery is fully discharged. Low Input Voltage Protection Adjustment: If we set a low input voltage protection for a 12V battery, connect input to a 10V voltage, then adjust RV1(clockwise to increase, counterclockwise to decrease) till UVLO light up. Now the protection voltage is 10V, that is to say, when battery voltage drops to 10V, module won't step up voltage and the output voltage will be same as input voltage. Note: 1, Input voltage must be more than 10V. 2, If a switch power supply is used as input, module should be connect to power and voltage should be adjusted well before connecting to load. When connecting to load, make sure to turn off the power supply first. 3, Power is related to input voltage, and when input voltage increases, power will increase.The maximum input current is 20A.For example, When input voltage is 12V, maximum power is 240W; input 24V, maximum power 480W; input 30V, maximum power 600W.
