What is a Transformer?
A transformer is a passive electrical device which is designed to change one AC voltage to another by magnetic induction. It “steps-up” or “steps-down”
voltage in order to match incoming supply voltage from the utility to the voltage required by the user’s end product. Typical USA supply voltages are 120,
208, 240, 277, 480 (and 575 in Canada). Common International voltages include 110, 220, 380, and 415.
What is an Isolation Transformer?
An isolation transformer is a transformer whose primary and secondary windings are separate for the purpose of isolating the circuit from the supply source.
What is an Autotransformer?
An autotransformer has only one winding, which is shared by the primary and secondary circuits. Autotransformers do not provide isolation but offer a
substantial savings when used to obtain small increments of voltage above or below the input voltage.
What is a Class II Transformer?
A Class II transformer is used to supply Class II circuits. Class II transformers have a maximum VA (Volt-Ampere) rating of less than 100 and a maximum
secondary output of 30 VAC. The maximum VA generally offered is 75 and the most common secondary voltage is 24 VAC. No load secondary voltage may
be as high as 29 VAC. All Class II transformers are either inherently or non-inherently limited. This means that the maximum output current of the
transformer is limited, either by the intrinsic coil impedance or by a fuse or circuit breaker. These transformers are designed to meet the requirements of U.L.
1585.
Inherently Energy Limited Transformers - Class II transformers up to 50 VA are “Inherently Limited” which means that the transformer, if overloaded,
will short itself out and fail safely, not requiring a fuse.
Non-Inherently Energy Limited Transformers - 60 thru 75 VA Class II transformers are generally protected by a resettable circuit breaker or a fuse
within the transformer secondary. Without this overload protection, the transformer would not satisfy the safety requirements for a Class II circuit.
What is a General Purpose Transformer?
General purpose transformers include any VA rating along with primary and secondary voltage ratings up to 600 VAC. Although internal fusing is an option, no
fusing is required. However, applicable U.L. specifications may require fusing in the end product. These transformers are designed to meet the
requirements of U.L. 506.
What is Voltage Regulation?
Voltage regulation is the percent of change in the output voltage when the load is reduced from full load to no load while the input voltage remains constant.
What is the effect of a load on a control transformer?
A control transformer is designed to provide rated output voltage at full VA. As the load decreases, the output voltage will go up. Conversely, increases in
load will result in lower output voltages. Typically, the smaller the VA size of the unit, the greater difference there is between no-load and full-load voltage.
