1 LCD can display input/output voltage, output current/output power/output capacity/output time; 2. CNC adjustment, accurate and fast, can boost and lower voltage, output voltage can be adjusted at from 0.5-30v, limit current 0-4a can be adjusted at ; 3. Anti-reverse connection protection of input end, which not burn out; 4. Anti-reverse irrigation at the output end, no additional anti-reverse irrigation diode is needed to charge the battery; 5. The module can be set to open/close by default; 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 automatically closed. Output ripple is small and PI filter is available; Thicken radiator fins.
