LCD can display input/output voltage, output current/output power/output capacity/output time; Numerical control adjustment, accurate and fast, step-down output, output voltage 0-50.00V can be adjusted arbitrarily, limit current 0-5.000A can be adjusted arbitrarily; The input terminal is against reverse connection, and the reverse connection will not be burned; the output terminal will not be burned if it is reversed; The module can be set to turn on/off by default; It has a of software protection mechanisms, and the protection is adjustable. When the working parameters of the module the protection , the output is automatically turned off.
