YUPVM ZK 4KX CNC Buck Boost Converter CC CV 0.5 30V 4A Power Module Adjustable Regulated Supply for Solar Battery Charging

2. CNC adjustment, accurate and fast, can boost and lower voltage, output voltage can be adjusted at will of 0.5-30v, limit current 0-4a can be adjusted at will; 4. Anti-reverse irrigation on the output, no additional anti-reverse irrigation diode is required to charge the battery; 3. Anti-reverse connection from input end, which will not burn; 1. LCD can input / output voltage, output current / output power / output capacity / output time; 5. Multiple software mechanisms are available, and the threshold is adjustable. When the working parameters of the module exceed the threshold, the output will be closed automatically.
