Features:  1. LCD can display input/output voltage, output current/output power/output capacity/output time;  2. Numerical control adjustment, precise and fast, step-down output, output voltage 0-50.00V arbitrarily adjusted, limit current 0-20.00A arbitrarily adjusted;  3. The output end does not burn when it is poured backwards;  4. The module can be set to turn on/off by default;  5. has a variety of software protection mechanisms, and the protection threshold is adjustable. After the module's working parameters exceed the protection threshold, the output will be automatically turned off;  6. Using synchronous rectification technology, high conversion efficiency: efficiency is above 90%;  7. Enlarge the heat sink and install a fan to enhance heat dissipation.     Specification:  Model Number: WZ5020L.  Output Power: 1000W.  Output current: 20A.  Output voltage: 50V.     Package included:  1 x Power Supply Module 1 x LED display
