PX-300/600R (Directional Long Range Acoustic Device) for traffic control

This product is being supplied to Korea Expressway Corporation and it is used in high traffic areas and areas prone to frequent accidents to ensure safe driving broadcasting and for secondary accident prevention purpose.

In addition, it is installed in the work vehicle and it is used together with the direction indicator to warn oncoming vehicles during the accident repair work to significantly reduce the accident rate of secondary collisions.

A driver of a car traveling at 100 Km / h on the expressway should be able to listen to the broadcast emitted from the transmitter with sufficient intelligibility from the 100 m point.

In order to meet the above requirement, a sound wave transmitter has been constructed in a horn structure with directivity function.

This is called a Directional Long Range Acoustic Device.
