Traffic signal lamp is made of high voltage low voltage to control

Solar energy traffic signal lamp manufacturer tip traffic lights is high voltage driver, weak current control.

Elv:

Weak current is as an electrical signal, usually refers to the dc or audio and video lines, network lines, telephone lines, usually within 36 v dc voltage.

High voltage:

High voltage is used as a kind of dynamic power, usually refers to some in the field of electrical power. Characterized by large power, large current and low frequency, communication is usually more than 24 v.

Any electrical equipment using the communication power supply due to high voltage area, therefore, traffic lights don't make an exception.

Traffic lights work heavy current and weak current is not only refer to the power supply voltage is concave and convex or current range, but it is the total system. Such as lighting, air conditioning, power due to high voltage field, and fire control, security, building intelligent system which are due to weak current field.

Of course, heavy current and weak current is not a completely independent space, weak current system operation also needs high voltage system for power supply, high voltage system should also be applied to a lot of weak current skills and equipment for automatic and intelligent control. Consequently, traffic lights were high voltage driver, weak current control.
