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).
