I present issue with this DROK DC-DC Numerical Control Step Down Voltage Converter, 6-65V to 0-60V 8A 400W Buck Voltage Regulator Stabilizer, Constant Voltage Constant Current Power Supply with Volt Amp Dual LED Display when I tried to regulate the voltage it doesn’t adjust it to a lower voltage output. I was using a 9v input source and was trying to adjust it counter clockwise to 6V but it doesn’t do anything. Also the current adjustment is not working. My Capstone teammate has another Step Down Voltage Converter same like this and the voltage is adjust but is not stable but the current is not adjusting. The order is # 112-9051019-0782608. Let me know if you need additional information. I need this in order to finish a circuit for my project. I also bought another two regulators, DROK DC-DC Numerical Control Step Down Voltage Converter, 6-65V to 0-60V 8A 400W Buck Voltage Regulator Stabilizer, Constant Voltage Constant Current Power Supply with Volt Amp Dual LED Display and DROK DC-DC Adjustable Buck Voltage Converter Stabilizer 6-32V to 1.25-32V LCD Display Constant Volt Amp 6V 12V 24V Step Down Voltage Regulator Power Module with USB Port Protective Shell .
