Variac These variable transformer deliver continuously
variable A.C. voltage. The output is variable from 0-270 Volts
from mains input of 240 volts. Contact between the winding
and load is through a carbon brush which covers at least one
turn of wire at all times. The areas of winding swept by the
brush is plated with metal which eliminates oxidations and
ensures a long working life with negligible maintenance.
