YTWL_CA100F Electrical Speed Limiter Speed Limiting 30KM/H ES6413/2019
1. Safety Requirement
All the four samples shall be tested for performance as prescribed in clauses below.
- All cable or harness connectors in the speedometer circuit shall be wired and sealed. All connections shall be soldered and insulated with a flame proof insulation tape of adequate length of such a color as to blend well with the rest of the vehicle
wiring.. - The speed limiter function or the Speed limiter device shall operate satisfactorily in its electromagnetic environment without unacceptable electromagnetic disturbance for any other device in the environment
- The speed limiter device shall pre-warn the driver, by way of a high frequency buzzer, optionally flashing light signal can be used that the set speed is being reached. This warming shall occur at 5% prior to the set speed and shall continue buzzing once
the set speed is achieved/ exceeded. - When the set speed is reached, the speed limiter device shall temporarily cause the engine to lose power.Engine power shall be reinstated at a speed not less than the pre-warning switch point,which is 5% below the set speed.
- A second (critical) set point should activate a retarder device (where legislated) when this set point is reached. This set point should be no more than 5% above the standard set point and shall, automatically, activate the retarder to ensure that the vehicle cannot exceed the preset limit.

Ethiopia Standard Electronic Speed Governor GSM GPS Vehicle Speed Limiter
- Fixed maximum speed limiting: Set a maximum speed according to the actual needs of vehicles. For example: if you require the vehicle speed does not exceed 60Km/h (or other appointed speed), the product will strictly control the vehicle speed does not exceed 60 Km/h (or other appointed speed) ;
- GPS speed data collection data collection ;
- Vehicle pulse speed ;
- Digital display controller adjustment.
