DC DC Buck Boost Converter Variable Voltage Regulator CC CV 0.5-30V 4A 5V 6V 12V 24V Power Module Adjustable Voltage Regulated Laboratory Power Supply

  • output voltage range is DC 0.5-30V, can be arbitrary adjustable.
  • output current can be 3A for long term use, if enhance heat dissipation, it can reach 4A.
  • max output power is 35W, if enhance dissipation, it can reach 50W.
  • LCD displays input/output voltage, output current/output power/output capacity/output time.The module can be set to ON/OFF by default.
  • Safe Protection: the module is with Anti-reverse connection protection of input end, so that it will not burn out when there is reverse connection.Anti-backflow protection at the output end. No need to add anti-backflow diode when charging. 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 turned off.
  • Application: the volt conversion board can be used as an ordinary buck/Boost module with over-current protection.
  • used as a high-power LED constant current driver module.
  • DIY a solar power controller, Battery Charging.
  • Output ripple is small and πfilter is available.Thick heat sink .Buck-boost Integrated.
