Overview
Kawish QDB-4A Car Actuator and Drive Tester Signal Simulator 12 V 24 V with Display Black for Testing Injectors Coils and Stepper Motors

The Kawish QDB-4A car actuator and drive tester is a universal diagnostic device for checking electronic components of a vehicle without the need for disassembly. It serves as a drive simulator, allowing you to verify the function of injectors, ignition coils, electromagnetic valves, and stepper motors. The colour display clearly shows frequency, duty cycle, current, voltage, resistance, and input power. It generates a PWM signal in the range of 1 Hz to 100 kHz with a duty cycle of 0 to 100%, covering the requirements of most models. The adjustable output voltage of 1.25 V to 11.5 V allows for safe testing of sensitive components. The built-in multimeter measures DC voltage from 0 to 30 V and resistance up to 1 MΩ. Depending on the selected mode, it can test valves, ignition coils, injectors, stepper motors, and output PWM and Hall signals. The anti-burning protection function safeguards both the tested parts and the device itself.

The Kawish QDB-4A tester is a practical tool for workshops and advanced DIY enthusiasts who need to quickly verify the function of drives and actuators. The wide range of tests covers diesel injectors, ignition coils, electronic throttle valves, control valves, and stepper motors. With the adjustable voltage of 1.25 V to 11.5 V and PWM signal generation, you can detect faulty components without complex disassembly. The clear display and control knobs for frequency and duty cycle facilitate precise test settings. The tool supports most common vehicle models and helps reduce the time spent diagnosing faults in electronic systems. Its compact dimensions and lightweight design make it easy to transport between workstations.
