The speed limiter is the world's highest level of generalization, security, advanced a car speed limiter.
Speed limiter features
1. Remote control setting function, you can set the parameters, the driver can't change the speed limit value, managers hold the remote control to have the right to modify;
2. Widely applicable, can be used in the electronic accelerator pedal car on 12 v ~ 24 v.
Light volumes, simple installation, use the full floating shock design, good seismic performance;
3. with the power cord for short circuit design, built-in over current protection circuit, strong stability;
4. Free maintenance, no mechanical contact, electronic control mechanical design features, installation at a time, a lifetime;
5. Can force the speed limit speed, idling away, do not affect a torque and horsepower, safe speed limit, also can open voice and light warning;
6. Limit speed down forcibly; within the speed limit the accelerator can free action;
7. With functions of intelligent learning step speed table, can be connected directly to all kinds of vehicle speed table, simple installation, also can equipped with GPS speed or speed sensor;
8. To memory live all kinds of parameters, a set of lifetime effective;
9. DC12V ~ 24 v voltage range.
10. Work small power consumption, is only 5 w.
