Voltage Regulators with Heightened Voltage

Three-level voltage regulator  673.3702 is intended for automatic voltage support on AC alternator.

It is applied at cars and trucks with alternators switched to “+”. The regulator compensates voltage drops. This may happen when the battery has not been charged enough or some devices lowing the voltage are used (for example battery separator).

Three-position switch is aimed for switching between the modes:

-     «14,2» position is intended for operation at  outside temperature between 0ºС and 20ºС, without additional devices which can make the voltage lower;

-      «14,9» and «15,2» positions are intended for operation at  outside temperature lower than 0ºС, or when additional devices which can make the voltage lower are connected.

Regulator 673.3702 is used instead of the regular one.
