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;
greater safety is afforded the operator.
The control transformer line is particularly
adaptable on applications where compact
construction is demanded.
Single-Phase Transformers
How to Select Single-Phase Units
1. Determine the primary (source) voltage
(the voltage presently available).
2. Determine the secondary (load) voltage
(the voltage needed at the load).
3. Determine the VA load:
Select a transformer rating equal to or
greater than the load VA.
VA = Load Volts x Load Amps
