Product Introduction:
1.Name:250W step-up constant current module
2.Character:non-isolated boost module
3.Input Voltage:DC 8.5-48V
4.Input Current:10A (max);if over 8A,please enhance heat dissipation
5.Quiescent Operating Current:10mA (when boosting 12V to 20V,output voltage becomes higher,and quiescent current will be higher)
6.Output Voltage:10-50V continuous adjustable
7.Output Current:10A (max);if over 6A,please enhance heat dissipation
8.Constant Current Range:0.2-8A
9.Output Power:=output voltage*5A
10.Operating Temperature:-40~85 celsius
11.Operating Frequency:150KHz
12.Conversion Efficiency:96% (max)
13.Overcurrent Protection:yes (if input is more than 13A,it will automatically decrease output voltage)
14.Input Reverse Connection Protection:yes (lower than 5A;if necessary,please serial connect with diode on input port)
15.Installation Way:4pcs 3mm screw holes
16.Connection Way:connection output
17.Size:70*36*13mm

Output Voltage/Current Adjustment Method:
1.Adjust RV1 potentiometer:according to your battery or LED,set output voltage to your required voltage,such as 10S LEDs voltage adjust 37V
2.Clockwise adjust RV2 potentiometer 30 circles,and set the output current to minimum value;connect with LED,adjust RV2 potentiometer to required current.When being used for battery charging,after battery discharges,then connect witht output,adjusst RV2 to required current

Application Fields:
1.DIY voltage-stabulized power:input 12V,output 12-50V adjustable
2.Supply power for electronic device
3.As vehicle power supply,supply power for laptop,PDA or various digital products
4.DIY high power laptop mobile power,matching 12V lithium battery pack
5.Solar battery board voltage stabilizing
6.Charging for storage battery and lithium battery
7.Driving high power LED lamp
