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 PR430 Car Power Inverter Features
Car Jump Starter & Battery Restoration: This 12V battery charger provides a 400A cranking current, easily starting car engines with a displacement of up to 5.0T. It also functions as a battery maintainer capable of reconditioning batteries that have been deeply discharged or severely depleted over time.
Multiple Protection Features & Selectable Operating Modes: The flash programming power supply includes five automatic protection functions: overcharge protection, overheat protection, low-voltage protection, short-circuit protection, and reverse polarity protection. Compared to standard chargers, this automotive battery charging tool offers higher power and supports both adjustable and fixed output modes. It is safe, reliable, and highly practical.
Programming Power Mode: Provides stable power to support ECU programming and decoding.
Car Jump Starter: Delivers an instant cranking current of 400A (non-continuous), allowing for easy starting of engines with displacements up to 5.0L.
Quick Charge Mode: Supports multiple battery charging methods. The device automatically adjusts the voltage and current according to the battery condition and stops charging when the battery is full to prevent overcharging.
Battery Reconditioning and Multiple Protection: It can recondition deeply discharged batteries. It also has overcharge, overheat, low voltage, short circuit and reverse polarity protection.
Powerful Performance: This programmable DC power supply battery maintainer allows for voltage selection between 10.8V and 15V. It features a 2.8-inch HD color screen that clearly displays operational data for easy reading. The button controls are simple and quick to use. The EM365 is suitable for standard car batteries, AGM batteries, EFB batteries, and gel batteries.
Five Language Options: Easily switch between English, French, German, Spanish, and Russian to meet the needs of customers from different countries.
AUTOOL PR430 Power Inverter For Car Operating Instructions
1. Turn on the unit switch.
2. Connect the battery power cables.
3. Select the test mode using the left and right buttons, then press the OK button.
4. Adjust the voltage and press the OK button.
5. Monitor the battery charging status on the LED screen.
6. Once the battery is fully charged, the machine will automatically stop.
EFB Battery Usage Instructions
EFB (Enhanced Flooded Battery) contains liquid electrolyte that is prone to boiling, and overheating during charging may cause fire or explosion. For safety reasons, the In-car Charging mode does not include an option for EFB batteries. If your battery is an EFB type, please remove it from the vehicle and select the External Charging mode for charging.
