Description: This DC-DC converter module is a buck (step-down) converter combined with a boost (step-up) converter, of which output voltage can be lower or higher than the input. With digital display, it features small size, high power, high efficiency and stable performance. It would maintain output voltage stability when input voltage is higher, lower or equal to output voltage. With high speed micro controller, this converter can accurately adjust output voltage and current. There are 10 groups built-in memory positions that allows storage or recall parameters, which is very convenient to use.4 digit display could show real-time voltage, current, power, capacity, etc. Features: Using advanced microprocessor, the converter can accurately adjust output voltage and current. The memory function supports storing 10 groups of parameters and can be freely stored or recalled. The converter supports output voltage stability function and constant voltage and constant current regulation function. 4 digit display could show real-time voltage, current, power and capacity, and you can select automatic or manual display in turn. There are output(OUT), constant voltage(CV), constant current(CC) indicator lights that shows real-time state. You can select whether to output automatically or not after power on. The voltage and current value can be saved by simply pressing one key.

Function 1: Save and recall parameters; display power and capacity. Function 2: Automatically display parameters in turn after output. On/Off(default off ): Long press "OK" button, then power on the module. It will display " --0-" , "--1-" , "--2-" in turn. Release "OK" button when it displays "--0-" to turn on/off function 0; r elease "OK" button when it displays "--1-" to turn on/off function 1; r elease "OK" button when it displays "--2-" to turn on/off function 2. ("--y-"=on, " --n-"=off) Package Includes: 1 x Converter Module
