Signal generator 15A excitation module 1Hz-160KHz PWM 1616 adjustable module LED display with pulse-frequency duty cycle
It is a power excitation signal generator up to 15A, i. high power PWM generator. You can easily adjust the output frequency and duty cycle by pressing a button on the micro module. It can be used to adjust the speed and brightness of the light. Widely used in manufacturing practice and technology. Quite often, the device is also used to open parking ramps, where you simulate a car in front of a closed ramp via an excitation antenna. The gate thinks that a car is standing by the ramp and opens the gate. Of course, you are standing in front of the ramp itself. Detailed description at the end of the text.

The frequency generators excite the device on the opening ramp. NICE LP21 - single-loop ground induction vehicle detector It uses a magnetic loop on the principle of metal detection.
Single-loop ground induction vehicle detector. On the principle of metal detection, it uses a magnetic loop located under the road surface (loop detector). The detector uses an induction loop to detect the presence of metal bodies (cars, motorcycles, etc.). It can be used for automatic opening / closing of gates, gates, entrance barriers and other devices. Replaces the Nice LP1 model.
Loop inductance: optimally 100 ÷ 300 µH, limit 25 ÷ 800 µH
2 - PRODUCT DESCRIPTION AND PURPOSE OF USE
• Barrier control
• Door and gate control
• Parking and traffic management
The operating frequency of the detector is adjustable in 2 steps on the front terminal block with 3 poles. The allowed frequency range is between 30 kHz and 130 kHz. The frequency depends on the selected frequency level and on the inductance based on the geometry of the loop, the number of windings and the power supply of the loop.
