Housing for mini step down converter (~41ct) -- Gehäuse für mini step down Konverter (~37ct)
Description
Housing for mini step down converter * single version * double version (e.g. for Arduino projects where 12V/5V/3.3V are required) * double version (with cable duct) * https://www.ebay.de/itm/10-X-Mini-DC-DC-Converter-Step-Down-Module-Adjustable-1V-5V-12V-16V-for-RC-M6I7/173061772539?ssPageName=STRK%3AMEBIDX%3AIT&var=471817091656&_trksid=p2060353.m2749.l2649 !!!PETG or ABS (the converter becomes quite warm)!!!! I made the double version so that if you have a 12V power supply, e.g. in an Arduino or NodeMCU project all three voltages 12V/5V/3.3V are available. ............................................................................................................................................ First measurement results show that the 1.8 output in the following constellation (in the housing) is quite realistic: in: 12,0V --> 9,0V/1,8A@~65°C (long term) Efficiency: 82,8% in: 12.0V --> 5.0V/1.8A@~67°C (long term) Efficiency: 82.6% in: 12.0V --> 3.3V/1.8A@~69°C (long term) Efficiency: 82.4% Have fun SG .-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- Gehäuse für mini step down Konverter * einzel Version * doppelte Version (z.B. für Arduino Projekte bei denen 12V/5V/3,3V benötigt werden) * doppelte Version (mit Kabelkanal) * https://www.ebay.de/itm/10-X-Mini-DC-DC-Converter-Step-Down-Module-Adjustable-1V-5V-12V-16V-for-RC-M6I7/173061772539?ssPageName=STRK%3AMEBIDX%3AIT&var=471817091656&_trksid=p2060353.m2749.l2649 !!!PETG oder ABS (der Konverter wird recht warm)!!! Die doppelte Ausführung habe ich gemacht damit man wenn ein 12V Netzteil hat, bei z.B. einem Arduino oder NodeMCU Projekt alle drei Spannungen 12V/5V/3,3V zur Verfügung hat. ............................................................................................................................................ Erste Messergebnisse zeigen das die 1,8 Ausgang in folgender Konstellation (im Gehäuse) durchaus realistisch sind: in: 12,0V --> 9,0V/1,8A@~65°C (langzeit) Wirkungsgrad: 82,8% in: 12,0V --> 5,0V/1,8A@~67°C (langzeit) Wirkungsgrad: 82,6% in: 12,0V --> 3,3V/1,8A@~69°C (langzeit) Wirkungsgrad: 82,4% Have fun SG .-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- Technical Parameters: Modular nature: non-isolated step-down Rectification: Synchronous rectification Input voltage: 4.75V-23V Output voltage: 1.0V-17V Output current: peak 3A, long time 1.8A Conversion efficiency: 96% (highest) Switching frequency: 340KHz Output ripple: 30mV (no load) Load regulation: ± 0.5% Voltage regulation: ± 2.5% Operating temperature: -40 ℃ to +85 ℃ Peripheral dimensions: 17 * 11 * 3.8 (L * W * H) (mm) Have fun, like, and share your makes...
