B3603 3A 6-40V In 0-36V Out DC-DC Digital Control CV/CC Step-Down Buck Converter Module

The B3603 DC-DC Digital Control Step-down Module is a digitally controlled constant voltage/constant current step-down (buck) converter module with a 4-character LED display. Its high speed micro controller provides precise control and display of voltage and current (actual and setpoint), output power, and capacity (power over time).  Indicator LEDs display Output On, Constant Voltage Mode and Constant Current Mode.  In its basic operating mode, the output voltage and current setpoints are entered using the Set, Arrow Up and Arrow Down buttons. The OK button saves the values and enables the output. While operating in Constant Voltage Mode, pressing the up and Down arrows increases or decreases the output voltage, In Constant Current Mode, the arrows control the output current. A short press of the "OK" button switches display parameters between voltage, current, power and capacity. A long press for 3 seconds will change the output to automatically scroll through the parameters, another
