Over Voltage Alarm WG1500090200 Sinotruk

Product Introduction

This Over Voltage Alarm WG1500090200 is an OEM electrical protection component exclusively engineered for Sinotruk heavy-duty trucks (e.g., HOWO series). It features a rugged black ABS plastic housing with a perforated acoustic design for clear alarm transmission, an integrated high-temperature resistant wiring harness, and a red quick-connect terminal for secure electrical connection. Calibrated to Sinotruk’s 24V electrical system specifications, it is built to monitor power supply stability in high-vibration, dusty, and temperature-fluctuating cab environments, adhering to strict OEM quality standards for reliable protection.

Core Functions

1. Real-Time Voltage Monitoring: Continuously detects the vehicle’s battery and generator output voltage, with precise threshold calibration to identify over-voltage conditions in the 24V electrical system.

2. Audible Alarm Notification: Emits a loud, distinct acoustic alert when voltage exceeds the safe operating range, immediately notifying the driver to prevent electrical system damage.

3. Electrical System Protection: Serves as a frontline defense against damage to sensitive electronic components (ECUs, sensors, controllers) caused by excessive voltage from generator malfunctions or charging system failures.

4. Harsh Environment Adaptability: The sealed housing resists dust, moisture, and oil intrusion; the reinforced wiring harness and corrosion-resistant terminal ensure stable signal transmission under heavy-duty operating conditions.

5. OEM Compatibility: Precisely matches the original vehicle’s mounting brackets, wiring harness pinouts, and voltage detection parameters, supporting direct plug-and-play installation without additional calibration or modification.
