ZK-4KX Programmable Digital Control Buck-Boost DC Adjustable Regulated Power DIY CV and CC Solar Charging Meter ShellItem NO.: ZK-4KX

ZK-4KX Programmable Digital Control Buck Boost Module

Product Highlights:

1. LCD can display input/output voltage, output current/output power/output capacity/output time;

2. CNC adjustment, fast, can increase or decrease voltage, output voltage can be adjusted at any time from 0.5-30V, and current limit can be adjusted at any time from 0-4A;

3. Input end anti reverse connection protection, reverse connection will not burn out;

4. The output end is anti backflow, and there is no need to add an additional anti backflow tube when charging the battery;

5. Module default on/off can be set;

6. Multiple software protection mechanisms, with adjustable protection thresholds. When the working parameters of the module exceed the protection threshold, the output is automatically turned off.

7. Small output ripple with π type filtering;

8. Thickened heat sink.
