4 Digit Communication Adjustable DC To DC Step Down Buck Converter Bench Power Supply, Voltage Consistency

Over-temperature protection engages when System temperature>80. The module uses a 1.54 inch 240*240 color HD display; Screen brightness setting: 0-5(6 level in total). Cooling fan logic: the fan will start if Output current>4A or System temperature>45. The fan will stop only when Output current<3.9A and System temperature<45. These protections work together to ensure stable DC To DC step-down operation and maintain voltage consistency.
