ZK-4KX CNC DC-DC Buck Boost Converter Module CC CV 0.5-30V 4A Adjustable Step Down Up Voltage Regulator

Features
1. Made of high quality material, solid, durable and strong conductivity.
2. Large LCD can display input/output voltage, output current/output power/output capacity/output time, easy to read.
3. CNC adjustment is very accurate and fast, and it also can boost and step down voltage. Output voltage can be adjusted from 0.5-30v, while the current can be adjusted 0-4A as you desired.
4. It features anti-reverse connection protection of input end, which will not burn out, safe to use.
5. Anti-reverse irrigation at the output end, no additional anti-reverse irrigation diode is needed to charge the battery;
6. The module can be set to open/close by default, easy to use.
7. It has 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 closed.
8. Output ripple is small and PI filter is available.
9. Thicken radiator fins helps the module to dissipate heat quickly, long service life.
