QDB-5A Multi-Purpose Automotive Tester Driver - DMM PWM Step Motor Diagnostic Instrument

QDB-5A Multi-Purpose Automotive Tester Driver

The Beacon QDB-5A is a powerful multi-function automotive diagnostic driver that combines essential testing and driving capabilities in one compact instrument. It serves as a digital multimeter, adjustable power supply, PWM signal generator, and step motor driver — making it indispensable for professional automotive workshops.

Key Features

• Digital Multimeter (DMM): Measures DC voltage (0-30V), DC current (0-1.8A), DC resistance (0-1MΩ), and capacitance (10nF-1000μF)
• Adjustable Power Output (VADJ): Variable voltage output from 1.25V to 14.5V with up to 2.5A current for component testing and activation
• PWM Signal Generator: Frequency range 1-100KHz with 0-100% duty cycle and 1.25-14.5V peak-to-peak output
• Step Motor Driver: Built-in stepper motor control for testing electronic throttle bodies and actuators
• Wide Input Range: Accepts DC 9-26V power input with 100W maximum power handling
• Direct Power Pass-Through: Power Out port provides direct pass-through of input voltage at up to 1.5A

Applications

• Automotive electronic component testing
• Sensor and actuator diagnostics
• ECU signal simulation
• Throttle body and step motor testing
• Professional workshop diagnostics
