It accepts primary voltages configured as 240\/480 V, 230\/460 V, or 220\/440 V and provides a 120\/115\/110 V secondary at 50\/60 Hz, making it suitable for powering control circuits and electromagnetic devices such as relays, contactors, and solenoids in industrial panels. The open-core design with copper windings and a heavy-gauge steel mounting plate helps minimize voltage drop during energization and supports reliable operation under typical control loads, with a focus on maintaining robust secondary voltage regulation. The TB-81215-F3 rating and construction align with Acme’s TB series open-core transformers, designed to sustain momentary inrush without sacrificing secondary voltage stability, and it carries a 10-year limited warranty. Its compact footprint measures 5.5 in x 5.3 in x 4.5 in, enabling straightforward panel mounting in space-constrained applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Acme","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656979087662,"sku":null,"price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_cdcd054c-875f-4c00-9944-637b50f0c453.jpg?v=1769464890","url":"https:\/\/plgautomation.com\/products\/industrial-tb-81215-f3-industrial-control-transformer","provider":"PLG Automation ","version":"1.0","type":"link"}
