Features: - LCD displays input/output voltage, output current/output power/output capacity/output time. - CNC adjustment enables accurate and fast adjusting. It can boost and lower voltage, with adjustable output voltage 0.5-30V, and adjustable current limit 0-4A. - Anti-reverse connection protection of input end, so that it will not burn out when there is reverse connection. - Anti-backflow protection at the output end. No need to add anti-backflow diode when charging. - The module can be set to ON/OFF 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 will be automatically turned off. - Output ripple is small andfilter is available. - Thick heat sink.
