Review of 400W DC Boost Converter input 8.5V-50V to 10V-60V

The module is explained fully with components. Minimum and maximum input and output voltage is tested. Setting Current limit is shown and tested with input and output of 9V, 12V, 15V 24V, 36V with different currents so we know how much current it can produces. Thermal image shown the hottest spot of the module. Link to resources and purchasing this module is below.

Specifications from Seleler. Test shown different. Watch video

• Input voltage: DC8.5V-50V
• Input current: 15A (MAX) exceeds 8A please enhance heat dissipation
• Quiescent current: 10mA (12V liter 20V, the output voltage, the higher the current will increase too quiet)
• Output voltage: 10-60V continuously adjustable
• Constant] range: 0.2-12A
• Temperature: -40 to + 85 degrees (ambient temperature is too high, please enhance heat dissipation)
• Operating frequency: 150KHz
• Conversion efficiency: up to 96%
• Overcurrent protection: yes
• Input reverse polarity protection: no
• Installation: 4 2.55mm screw holes
