<ul><li>Feature: 
1. The LCD can display voltage input and output, output current, output power, output capacity, and output time. 
2. Numerical control adjustment is accurate and fast, can increase and decrease voltage, output voltage can be adjusted arbitrarily from 0.5‑30V, and limit current can be adjusted arbitrarily from 0‑4A. 
3. The input terminal is protected against reverse connection, and the reverse connection will not burn. 
4. The output terminal is anti‑backflow, and there is no need to add an anti‑backflow diode when charging the battery. 
5. The module can be set to turn on/off by default, with low output ripple and π‑type filtering. 
6. After the module's working parameters exceed the protection threshold, the output will be automatically turned off, the heat sink is thickened, and the heat dissipation effect is good
