A comprehensive range of
single and 3 phase phase variable auto transformers covering ratings from 1 amp
to 28 amps per phase. Used for the variable control of voltages from 0 to 270V
1ph and 0 to 470V 3ph with low power losses. Units can be supplied as either
open or enclosed types with the option of double wound transfomers to give total
isolation.
Also units can be
supplied to give a variable DC output via a bridge rectifier and motor drive
options are also available. Larger units can be supplied by paralleling two or
more stacked versions and all types can be fully protected from overload and
short circuits.
They can also be fitted
with full metering if required. The unique silver or nickle plated wiper path
design gives high reliability and long life. All windings are wound on high
quality low loss
toroidal cores giving efficiencies up to 98%.

other non standard voltages, currents and power ratings available
