What's new in the ZX?

1. Zero crossing switch

In order to minimize the load on the relay contacts and thereby on the connected device, the processor calculates a delay based on the determined switch-on and switch-off times, which corresponds to the zero crossing of the mains voltage.

   It is de-energised, i.e. without load for the contacts of relay and the energy receiver.

What is the advantage of electromechanical relays:

• Minimal heat generation, independent of load.
• Double, genuine galvanic isolation: switching contacts and from driver.
• Robust against current and voltage changes / interference.

The disadvantage that the contacts wear out or 'stick' due to the high inrush current is prevented by zero-crossing switching.

2. Detection of which line (L/N) is switched.

3. Recognize that a relay has actually switched.

Otherwise, everyone rates the features of the ADV version.
