AT35 DC-DC Step Up Step Down Converter Module Buck Boost Board Constant Current Constant Voltage Supply DIY 3A 35W

Main Product

Product Parameters:

Input voltage 5~30V Output voltage: 0.5~30V Output current: 3A (heating up to 4A) Output power: 35W (heating up to 60W) Output rple: 20mV (12V 3A), and the universal module far exceeds 100mV! Conversion efficiency: 87~91% (Boost); 87~89% (Buck) (The parameter will vary according to preure and load) Input overcurrent protection: 10A fuse Input protection: high efficiency MOS type Input undervoltage protection: Yes Output overcurrent protection: yes Working frequency: 180KHZ Board size: 69 * 28 * 21mm

Feature:

1. It can step up or step down. Regardle of the input voltage, the output voltage can be fixed at 12V. When the input voltage is 12V, the output voltage can be reduced to 5V or boosted to 24V. Constant current function. When the input voltage is between 5-30V, it can charge batteries, lithium batteries, AA rechargeable batteries, etc.

2. You can set the constant current value without the help of a .

3. Easy to use single turn potentiometer and scale.

4. Really ultra-low output rple voltage! Low ESR + two-stage filter, suitable for audio amplifier board, og circuit power supply!

5. Perfect protection function! MOS type anti-fback circuit, input under-voltage shutdown, output over-current protection.

6. Turn light function! Easy to use! Constant current charging When the red light and blue light are on, the constant voltage charging only has bright blue light, close to full blue and green light, and full light is only when the green light is on!
