Component Overview
- Series Output Diode: MBR20100CT (Both diodes in parallel)
- Input Capacitance: 2x 220uF 50V Electrolytic Caps
- Output Capacitance: 2x 220uF 50V Electrolytic Caps
Operation Overview
- CV-ADJ Potentiometer adjusts constant voltage limiting (Anti-Clockwise to Increase)
- CC-ADJ Potentiometer adjusts constant current limiting (Anti-Clockwise to Increase)
- When in constant current mode, the minimum the converter can reduce the output voltage to is the input voltage. This is due to the boost converter circuit configuration which prevents the module from being able to step-down voltages. What all this means is that the module is unable to limit the output current to zero when being used in the constant current mode.
