Automatic voltage switches consist of a dedicated driver associated with a Triac for bi-voltage 120/240 V applications. The controller’s main features are full 50/60 Hz compatibility, the triggering pulse train of the Triac, the parasitic filter and low power consumption. Triac devices have a maximum voltage specified at 600 V and a maximum current up to 12 A.
They are available in DIP 8 packages for the driver and TO-220, TO-220I packages for the Triacs.
