Zero-cross switching: Switching precisely at a poin

Switching devices that are designed for a C load generally deal with the switching currents in a better manner. In doing so, Theben uses a particularly efficient solution, such as a so-called zero-cross switching. This calculates the zero crossing of the sinus curve of the alternating voltage. At this moment, the switch-on current is minimum when switching. That protects the relay contact and extends its service life, even at nominally high switching loads.

Overview: switching units with zero-cross switching

From the light bulb to the LED lamp: with features such as zero-cross switching, Theben offers compact self-sufficient devices for every application from simple time switches to astronomical time switches with weekly program.

 

 

Astronomical digital time switch with weekly program

Digital time switches from a width of 2 TE (The time switches with an operating voltage of 12鈥24 V do not have a zero-cross switching) are equipped with a zero-cross switching to avoid wear and tear of relay contact and light source, i.e. prolongs service life of light source.
