AUTOOL EM385 Engine Ecu Programming Working Principle
An engine ECU programming power supply is an adjustable power source based on power electronics and control circuit technology, capable of providing precise and stable voltage and current output. Its working principle includes converting the input power into DC through rectification and filtering, then regulating the power (such as via switching or linear regulation) to achieve the target output voltage and current. A feedback system continuously monitors and adjusts the output in real time to ensure stability. The control modes support both local operation (buttons/knobs) and remote communication (USB, RS232, etc.). It also features protection functions such as over-voltage, over-current, and over-temperature protection. With characteristics like high precision, wide output range, and high efficiency, it is widely used in scenarios such as power inverter for car, automotive ECU programming, showroom applications, and production testing.
