GabrielViiEscrito hace 2447 días.build feels solid and hooked up with RC 3S lipo tested to power up laptop, feels warm after 15min running input voltage at 11.4v while output 19.23V @ ~1.1A with laptop under idle, unable to test load due to my multimeter unable to properly read current draw.....
second & third pic show size comparison to old 5A boost regulator that failed after 3 months usage
Por pe1osq18/08/2015I used this module to build a variable power supply.
I use an input voltage of 12 volts (from a computer power supply) and need this module to create a variable (settable via the potmeter) output voltage ca 1 - 30 volt.
With output voltages over 12 volts everything works fine.
In the step down mode (voltages below 12 volt) the output voltage is not stable. For instance if I set the output voltage to 5 volts and apply no or very little load, then the outputvoltage "swings" between 4.8 and 5.3 volt.
Por ArturKrajewski24/05/2020Great product. I used it to build a bench power supply with 2 variable channels and it works fine.
