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

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