The image shows a Power Supply Transformer from the LECXO brand. Its specifications written on the package: * Input: 24V DC * Output: 12V DC * Current: 5A * Function: To step down the voltage from 24 volts to 12 volts for devices that operate on 12 volts. Often used with: * 24V car and truck systems. * GPS tracking devices. * Surveillance cameras. * LED screens and lighting systems. * Any device operating on 12V and requiring up to 5 amps. The image shows a Parking Sensor System kit for cars. Specifications visible on the box: * Number of sensors: 4 sensors. * Audible alert when approaching an obstacle. * Detection range approximately: from 30 cm to 200 cm. * Works automatically when reverse gear (R) is engaged. * Equipped with a self-inspection feature for the sensors. Considering the previous image, a 24V to 12V (5A) transformer can be used if your car or truck operates on a 24-volt system while this sensor operates on 12 volts. The transformer is connected first, and then the sensor unit is supplied with 12 volts. If the car is: * Camry, Accord, Hilux gasoline, or most small cars → 12-volt electrical system and you do not need the transformer. * Truck or equipment operating on 24 volts → You need the transformer shown in the first image.
