DESCRIPTION
The GS-R218 is a switching voltage regulator that
can deliver an output current of 1,5 A at 18 V when
supplied by a car battery.
The regulator uses a cigar lighter case with a coiled
cord and it is protected against overloads and short
circuits at the output (latching overload protection:
to restart the regulator after the intervention of the
overload protection, the input voltage must be
switched OFF and ON again).
