Application Description
Transformers provide
stepped-down voltages to
machine tool control devices,
enabling control circuits to
be isolated from all power
and lighting circuits. This
allows the use of grounded
or ungrounded circuits that
are independent of the power
or lighting grounds; thus,
greater safety is afforded
the operator. The control
transformer line is particularly
adaptable on applications
where compact construction
is demanded.
Note: The MTG “open core-coil
design” has been superseded by
the epoxy-encapsulated core-coil
design MTE with no change to
dimensions or functionality.
