AUTOOL EM385 Car Power Inverter

The AUTOOL EM385 Car Power Inverter is a high-quality, high-performance professional 3-IN-1 inverter programming power supply. It provides a stable power source for vehicles during ECU programming and also features functions such as battery restoration and fast charging. By switching modes, it can also be used as a charger and for jump-starting 12V car batteries.

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.

AUTOOL EM385 Car Power Inverter Features

Power Programming Mode: The AUTOOL EM385 inverter programming power supply provides a stable power source to assist in programming or decoding the vehicle’s Electronic Control Unit (ECU).

Fast Charging Mode: During the charging process, the device automatically adjusts the charging voltage and current based on the battery’s condition. It will stop charging once the battery is fully charged to prevent overcharging and extend the battery’s lifespan.
