ماژول DC-DC افزاینده 250 وات با پی سی بی آلومینیومی

250W boost constant current module

Module properties: non-isolated step-up module (BOOST)

Input voltage: DC8.5V-48V

Input current: 10A (MAX) exceeds 8A please enhance heat dissipation

Quiescent current: 10mA (12V liter 20V, the output voltage is higher Shizuta current will increase)

Output voltage: 10-50V continuously adjustable

Output current: 10A MAX exceed 6A please enhance heat dissipation (input, output related to pressure, the greater the pressure the smaller the output current)

Constant Range: 0.2-8A

For even more power, two modules can be used in parallel, such as the output to 10A, two modules can be used in parallel,

Working temperature: -40 to + 85 degrees (ambient temperature is too high, please enhance heat dissipation)

Operating frequency: 150KHz

Conversion efficiency: up to 96% (efficiency of input and output voltage, current, pressure related)

Overcurrent protection: Yes (input exceeds 13A, automatically reduce the output voltage, there is a range of errors.)

Input reverse polarity protection: Yes, (less than 5A such as the need for more in the reverse current in the input string into the diode)

Size: length 70mm width 42mm height 13mm

the output voltage / current adjustment method:

     1- adjust RV1 potentiometer, according to your battery or LED, the output voltage is set to your desired voltage value. 10 LED string voltage regulator such as 37V.

      2-adjust RV2 potentiometer clockwise 30 laps, the output current is set to a minimum, connected LED, adjust RV2 potentiometer to the desired current. After the battery for charging, the battery fully discharged, and then to output, you need to adjust RV2 current (for charging must use a battery completely discharged before being allowed to adjust, because the battery charge remaining in Vietnam more, the charging current is smaller.)

 Please do not adjust the current short-circuited manner, the circuit structure of the booster module can not be short-circuited by way of transfer.
