Power supply for electromechanical lock

Power supply unit

The power supply for intercom is an integral part of the electrical circuit, without which the correct operation of the interphone equipment is impossible. The thing is that the lock, as well as the control unit, can’t be connected to the 220 V network directly, alternating current needs to be converted to a low DC voltage.

This is the function of the power supply for the intercom. As a result, the value necessary for the normal functioning of the call unit and the locking device is reached. Basically it is 12 V and 15-18 V for the outdoor panel.

When choosing a PSU for intercom, you should take into account its technical parameters, as well as the conditions in which it will be used. Electrical work should be trusted only by professionals. This will help extend the life of the equipment and avoid injury.
