WOYO CTB007 Truck 24V‑12V‑14.5V OBD2 Converter | True‑RMS 16‑Pin Voltage Tester for Heavy‑Duty Diagnostic Protection

WOYO CTB007 TRUCK Professional OBD2 Tester 24V to 24V/12V-14.5V Regulated Output Voltage Converter It exposes all OBD-II pins, monitors live voltage (True RMS), and enables a safe, fast connection with other diagnostic/programming devices. WOYO CTB007 Key Features: 1. Expensive Diagnostic Tool Protection： Compatible with diagnostic protocols; 12V-compatible tools are safeguarded. 2. Step-Down Regulated Conversion： Delivers 4A 50W power, adjusting output voltage to 12V–14.5V for diagnostic equipment protection. 3. Accurate Current Display： Precisely shows load-side supply current. 4. HD LCD Screen： Simultaneously displays multi-channel RMS voltage values, allowing real-time pin status checks and easy fault troubleshooting during diagnosis. 5. Dual Operation Modes： Press the Up and Down buttons simultaneously to activate direct voltage mode (Input = Output); press any button to revert to regulated mode. WOYO CTB007 Operation Instructions： 1. Precise Regulated Voltage Control: Short press to adjust output voltage precisely (12V–14.5V). 2. Direct Mode Activation：Press & hold both buttons simultaneously for ≥2s to enable "Input Voltage = Output Voltage" direct mode. 3. Regulated Mode Resume: After releasing, press either button randomly to restore regulated output mode. 4. Real-time OBD-II Pin Voltage Monitor (VRMS / true RMS): Power/ground integrity: e.g., pin 16 (+B) and pins 4/5 (grounds). Bus activity on CAN / K-Line: checks whether static/dynamic levels look reasonable; a green background indicates dynamic values. Pin assignment sanity-check: quickly validates expected wiring on retrofits or suspect harnesses—replacing basic VPP voltage checks. 5. Signal Status: Pin background flashing green = dynamic signal. 6. PIN 16 High/Low Voltage Audible Alarms: Low-voltage (slow beep): 24 V systems: < 23.6 V High-voltage (fast beep): 24 V systems: > 31 V 7. Ground Status Indication: Pins 4 or 5 show OPEN when no ground is detected, and GND when a valid ground is present. 8. External power input: 24-31V DC, barrel 5.5 × 2.1 mm.
