PWM Power Probe (20A)

The Ultimate Tool for automotive electrical diagnostics! 

Modern vehicles rely on sophisticated electronic solenoids, sensors, actuators, and PWM-controlled systems. Troubleshooting these components requires more than a multimeter. The PWM Power Probe combines voltage testing, resistance measurement, direct power supply, and programmable PWM simulation into one rugged, intuitive tool. Whether you're a professional technician or a serious DIYer, this device saves time, reduces guesswork, and delivers reliable diagnostics every time.

Exclusive Invention

v  Live Adjustable PWM – simulate real-world signals to test components under load.

Functions

1. Voltage Test – measures DC voltage up to 100V.

2. Resistance Test – three auto-ranging scales: 0.01Ω–20Ω, 0.1Ω–200Ω, 1Ω–2000Ω.

3. Direct 12V Power Feed – provides battery power for component testing.

4. PWM Power Output – 12V, 20A max, adjustable frequency (7–1000Hz) and duty cycle (5–95%).

5. Timer Control Test – automated testing from 1 minute to 6 hours.

Features

v  Reverse Polarity Protection – no damage if connected backwards.

v  Self-Recovering PTC Fuse (20A) – automatically resets after a short-circuit event.

v  Input Voltage Monitoring – audible alarm if battery voltage drops below 12V.

v  Over-Voltage Protection – prevents damage during voltage measurement up to 100V DC.

v Automated Testing – set parameters and let the tool operates at with enabled timer-controlled solenoid tests.

v  Data Logging – stores up to 100 test results for comparison and reporting.

v  All-in-One Tool – replace multiple devices with one professional-grade unit.

v  Data Memory – stores 100 test results with recall function.

v  Temperature Monitoring – external sensor included (°C/°F selectable).

Benefits

For Professional Garages & Technicians:

v  Faster Diagnostics: Quickly test fuel injectors, EVAP solenoids, boost control solenoids, and more without removing them.

v  Accurate Simulation: Replicate OEM PWM signals (7–1000Hz, 5–95% duty cycle) to verify component operation.

v  Prevent Comebacks: Use the timer test to stress-test components over time, ensuring they won’t fail shortly after repair.

v  Professional Reporting: Store test results (T-001, T-002, etc.) to show customers proof of operation or failure.

For DIY & Enthusiasts:

v  No More Guesswork: Easily check if a solenoid or sensor is working without expensive dealership tools.

v  Learn & Experiment: Understand how PWM systems work by adjusting frequency and duty cycle in real-time.

v  Safe & Protected: Built-in short-circuit and reverse-polarity protection prevent costly mistakes.

v  One Tool, Many Uses: Use it as a power supply, voltmeter, ohmmeter, and signal generator.

Safety provisions

Your safety and the protection of vehicle electronics are our top priorities. The PWM Power Probe is designed with multiple layers of protection and complies with international standards.

Precautions

v  Use only with a 12V automotive battery or regulated power supply.

v  Do not exceed 100V DC during voltage testing.

v  Ensure connected components can handle up to 20A PWM output.

v  Disconnect power before servicing any vehicle wiring.

Frequently Asked Questions (FAQ)

Q1: Can this test fuel injectors?

A: Yes. Use PWM output mode to simulate the injector signals and measure current draw of a circuit.

Q2: Is it suitable for diesel systems?

A: Absolutely. It can test glow plug relays, EGR solenoids, and fuel pressure regulators.

Q3: How do I update the firmware?

A: The device is ready to use. Future update is not necessary.

Q4: What if I overload the output?

A: The PTC fuse will self-reset once the overload is removed and the unit cools.

Q5: Can I use it on 24V systems?

A: No. Input is designed for 12V only. Use a regulated 12V source if testing 24V vehicles.
