2-Stage Thyristor Control Unit
REOTRON MEW 2-S
REOTRON MEW 2-S, singlephase,
microprocessor
controlled, thyristor regulators
are suitable for resistive or
inductive loads. Fast rise times
on each half-wave (determined
by the firing phase-angle) are
minimised by using voltagefollowing control. In this way an
almost true current sine
waveform is produced at the
load. The external loadtransformer is wound in a
manner that enables it to
produce a base voltage level
from one winding. A second
winding is used adjust the
overall voltage range. The
relationship between the two
voltage levels is controlled
automatically and is not
dependant on the set-point
level. The controller is provided
with a MCB, a separate voltage
supply and integral fuses.
