250W Boost Constant Current Module

Product Information:

【Module name】: 250W boost constant current module

【Module properties】: Non-isolated boost module (BOOST)

【Input voltage】: DC10V-40V

【Input current】: 6A (MAX)

【Static working current】: 10mA (when 12V rises to 20V, the higher the output voltage, the higher the static current will increase)

【Output voltage】: 10-50V continuously adjustable (default output is 19V, if you need other voltages, please explain to the shopkeeper.)

【Output current】: If 6A MAX exceeds 4A, please strengthen heat dissipation (related to the input and output voltage difference, the larger the voltage difference, the smaller the output current)

【Constant current range】: 0.2-6A

【Output power】: = input voltage*6A, such as: input 12V*6A=72W, input 24V*6A=144W,

                           Input 36V*5A=180W, input 48V*5A=240W,

【Working temperature】: -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high)

【Working frequency】: 150KHz

【Conversion efficiency】: 92%-96% (efficiency is related to input, output voltage, current, and differential pressure)

【Input reverse connection protection】: Yes, (less than 5A, if you need a higher reverse connection current, please connect a diode in series with the input)

【Installation method】: 4 3mm screw holes

【Wiring method】: Wiring output

【module size】: length 70mm width 36mm height 13mm

【Module unit weight】: 50 grams

Output Voltage/Current Adjustment Method:

1. Adjust the RV1 potentiometer and set the output voltage to the voltage value you need according to your battery or LED. For example, the voltage of 10 strings of LEDs is adjusted to 37V.

2. Turn the RV2 potentiometer clockwise about 30 turns, set the output current to small, connect the LED, and adjust the RV2 potentiometer to the current you need. For battery charging, after the battery is fully discharged, connect it to the output, and adjust RV2 to the current you need. The more the charging current is, the smaller the charging current.) Please do not adjust the current in a short-circuit manner, and the circuit structure of the boost module cannot be adjusted in a short-circuit manner.
