Built to handle 12V and 24V environments, it enables independent ignition tests, fuel injector drive, solenoid valves, metering units, and idle\/stepper motors with precise PWM control. By generating realistic duty cycles, frequencies, and voltage levels, it helps technicians quickly identify faulty coils, injectors, actuators, or control circuitry, reducing diagnostic time and guesswork.\u003c\/p\u003e \u003ch2\u003eMain Description\u003c\/h2\u003e\n\u003cp\u003eKey capabilities include driving ignition coils with configurable coil type and module type settings, testing gasoline and diesel fuel injectors, and exercising various duty‑ratio controlled components such as solenoid valves and metering units. The device also powers and tests idle stepping motors, instrument stepping motors, and even headlight follow‑up steering motors, making it a versatile lab tool for modern engine management systems. A Hall sensor feature offers adjustable output frequency, amplitude, and duty cycle to simulate feedback from sensors like occupancy, air conditioning pressure, or air flow meters that rely on duty cycles. The unit supports a broad voltage range (12V–24V) and includes reverse connection protection and overcurrent protection for safer bench testing. With PWM drive up to 100 kHz and a configurable voltage range (1.25V–11.5V), it mirrors real‑world operating conditions to reveal intermittent or performance‑based faults that would be missed by static tests. This upgraded QDB‑3A model brings robust, multi‑purpose testing to workshops and training labs who need rapid, reliable diagnostics with real‑world signal fidelity.\u003c\/p\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003cp\u003eLanguage support is available to accommodate diverse teams: English, Russian, Portuguese, Spanish, French and Chinese.
