Import Car Speed Limiter — Buy in Bulk from Supplier in China

Guangzhou Nine Chip Electron Science & Technology Co., Ltd. offers a Car Speed Limiter designed to cap vehicle speed between 10 and 120 km/h. The unit limits speed with a deviation of ±1 km/h and operates from a 9‑28 V supply while drawing only 2 W of power. It is built to function across a wide temperature span from - 35 °C up to 80 °C and can tolerate relative humidity levels of up to 90 %. The device also includes anti‑vibration performance of 20‑50 Hz at 1 g and meets an electromagnetic compatibility pulse voltage of 4000 V.

The limiter’s electronic components are housed in a robust enclosure that tolerates extreme ambient conditions, a common requirement for fleet vehicles operating in varied climates. Typical industry practice adds a CAN‑bus communication interface for integration with vehicle control units, although this particular model does not list a specific protocol. Standard warranty periods for similar electronic speed control units are twelve months, providing a baseline for after‑sales support. The design follows typical automotive electronic standards for safety and durability.

The product can be installed in passenger cars, school buses, heavy‑duty trucks and specialised vehicles such as garbage trucks and tankers. Fleet managers and vehicle manufacturers often select such devices to enforce speed policies and improve safety. Suppliers usually require confirmation of minimum order quantities, lead‑time estimates and preferred Incoterms before finalising a contract, so buyers should request these details directly from the supplier.

The company is listed in the harbour trust tier and currently shows a response rate of 0.00, indicating that buyers should verify current communication availability before proceeding.

The supplier’s catalogue lists the Car Speed Limiter as suitable for a broad range of vehicle types, from passenger cars to heavy trucks. No specific minimum order quantity, price list or lead‑time is disclosed in the public data, so interested importers must request these details directly from the company.
