CDVI Security F0502000017-B Automatic door opener

The CDVI electric door openers of the S series can be used in many different ways. The electric door openers are symmetrical and are therefore suitable for DIN left and DIN right doors. The closing plates are adjustable and are therefore suitable for almost all doors. All E-door openers of CDVI have a built-in varistor that protects against damage due to residual voltage/residual voltage. A (freewheel) diode is therefore no longer required, the door openers are connected to AC or DC, and polarity does not have to be taken into consideration. All these properties lead to universally usable devices, the devices of the S-series can be used almost everywhere without restriction.
