CET Technology designs and manufactures high quality step down transformers for any voltage or application, which can either be isolating or non-isolating (autotransformers.)
What Are Step Down Transformers Used For?
Step Down Transformers are transformers that convert a higher voltage to a lower voltage. They are most often used to adapt equipment to operate at different line voltages (e.g. to run a 120V device on a 220V AC line); or to convert line voltage to a lower, safer voltage for distribution throughout a piece of equipment (e.g. converting 120VAC to 24VAC to power various systems within a larger piece of equipment.) It is also possible to have a Step Down Transformer with multiple secondary windings that can be loaded individually or simultaneously. This allows the designer to generate multiple lower voltages from the same AC line.
Isolating vs. Non-isolating Step Down Transformers:
Step Down Transformers can be either isolating or non-isolating. Here is the difference between the two:
Isolating Transformers: have separate primary and secondary windings, with one or more layers of insulation between them. There is no electrical connection between the primary and secondary of an isolating Step Down Transformer.
Non-Isolating Transformers: (also called autotransformers) have only a single winding with multiple taps. Voltage is applied to one of the taps, and the secondary voltage is produced on a different tap. Non-isolating transformers allow similar conversion of voltage, but they’re usually smaller and less expensive than an equivalent rated isolating step-down transformer.

Browse CET Technology’s selection of Step-Down Transformers and request a quote online. Our step down transformers can be used to adapt to common lower voltages, including:
- 220v to 110v
- 120VAC to 24VAC
CET custom step down transformers are frequently connected to AC line voltage, so they are usually designed to meet the requirements of UL5085 for heat rise, isolation, and other safety requirements. Further, if the end-use equipment has to go through agency approvals, CET will work directly with the NRTL, be it UL, TUV, ETL, BV, or someone else, get the transformer approved.
