This transformer can also be wired to be used as an autotransformer. For more information, see "Economical Auto Arrangements" under related documents.

This ACME transformer comes enclosed in a UL Type 3R encapsulated enclosure to allow indoor or outdoor use without the need for weather shields. The enclosure is also UL listed and CSA certified to meet or exceed all listing criteria including NEMA, ANSI and OSHA standards.

All lead wire terminations are copper for a much better conductivity. It is also lighter, and more flexible for easier wiring. This model has a front access wiring compartment with various knockouts for wall mounting. It's a quality product that is easy to set-up and easy to work with.
