Droking NC Power Supply Voltage Regulator DC 6-40.00V to 0V-32.00V Adjustable Buck Converter Voltmeter Ammeter 160W Step Down Converter Programmable Power Supply Module

It's difficult to say anything negative about this power supply.It is spot on with its functionality and the digital readings are accurate when checked against my multimeters.The only area which could be improved is the instructions for set up but with the power supply infront of you everything becomes clear very quickly.There are cheaper constant voltage / current power supplies but because I want to use this for multiple purpose the digital meter facility more than justifies the additional cost.
