This circuit acts on a relay disconnecting the load when the input voltage exceeds the set limit. The transformer is 12 V secondary according to the relay used.
This circuit is intended to increase the width of a pulse. The circuit is TTL and can be used as a...
This transistor amplifier does not use a source with a transformer being fed directly by the power...
In the figure we have a protection circuit for sources that we find in a 1994 technical...
