3. Anti-reverse connection protection from input end, which not burn; 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; 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.
