This Siemens MT0200A industrial power transformer has a 200 VA power rating, a voltage letter designation of A, and reduces 240 x 480, 230 x 460, or 220 x 440 V (primary voltage) to 120/115/110 V (secondary voltage). A silicon steel-laminated core and copper magnet wire increase transformer efficiency, which decreases the destabilizing effect of inrush current on secondary voltage. Epoxy-encapsulated transformer coils resist moisture, dust, and industrial contaminants, and built-in terminals and barriers resist breakage. Steel mounting brackets provide stable mounting and slotted mounting feet make installation easier. The thermal insulation class for this transformer is 105 degrees C with a 55 degree C (131 degrees F) temperature rise. This power transformer is Underwriters Laboratories (UL) listed and CSA International certified, and is suitable for use in transforming electrical power for machine tools and industrial control circuits.

They also isolate control circuits from power and lighting circuits, which reduces electronic interference. Transformers accommodate specific primary voltages and currents, and supply specific secondary voltages and currents. Power transformers are used in a wide range of applications, such as home electronics power supplies, machine tools, and the distribution of electricity.

This replaces the original transformer that burned out on a 1950’s model Tree knee mill. Works great.

Worked fine, screw terminals were a little hard to get to

This transformer is well built and has a few wiring options between the primary and secondary sides. The fuse on the secondary is optional and not included but it's a standard size so it is easy to source.
