250W Booster Module

The 250W Booster Module is a very suitable voltage booster/regulator for projects that require high power. The board can boost 8.5-48V input voltage to 10-50V continuous adjustable.

It is especially useful for automotive 12V applications, where standard 12V battery power can be boosted to 19V for use as a laptop computer power supply, or to 18V or 24V for other applications requiring higher voltages.

Features:

• Name:250W step-up constant current module
• Character: non-isolated boost module
• Input Voltage: DC 8.5-48V
• Input Current:10A (max);if over 8A,please enhance heat dissipation
• Quiescent Operating Current:10mA (when boosting 12V to 20V,output voltage becomes higher, and quiescent current will be higher)
• Output Voltage:10-50V continuous adjustable
• Output Current:10A (max);if over 6A,please enhance heat dissipation
• Constant Current Range:0.2-8A
• Output Power:=output voltage*5A
• Operating Temperature:-40~85 Celsius
• Operating Frequency:150KHz
• Conversion Efficiency:96% (max)
• Overcurrent Protection: yes (if input is more than 13A,it will automatically decrease output voltage)
• Input Reverse Connection Protection: yes (lower than 5A;if necessary, please serial connect with diode on input port)
• Installation Way:4pcs 3mm screw holes
• Connection Way: connection output
• 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 with output, adjust RV2 to required current

Application Fields:
