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.
Almost all of the devices of the top2 series are equipped with the motion detector theLuxa S and the presence detector PlanoCentro.
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.
