It offers multi‑tapped primary voltages—220\/440\/550 VAC; 230\/460\/575 VAC; 240\/480\/600 VAC—and secondary options of 120\/100 VAC, 115\/95 VAC, or 110\/90 VAC to suit diverse electronics and motor-control loads. The open‑core and coil construction uses copper windings on silicon steel laminations for reliable regulation, while integrally molded terminal blocks with isolation barriers and series‑parallel links simplify installation and wiring. The TB81005 is rated for 50\/60 Hz, single‑phase operation, and is built with a 130 °C Class B insulation system for durability in industrial environments; its mounting plate accommodates various installations, and the unit weighs about 21 lb with dimensions around 6.43\" L x 5.25\" W x 4.47\" H. Typical applications include motor starters, contactors, solenoids, and timers, or any loads requiring a safe, regulated control voltage, with tighter secondary voltage regulation than many competing transformers; manufacturer notes emphasize copper windings, open‑core design, and focus on voltage stability under inrush conditions, plus a 10‑year limited warranty from Acme Electric, a Hubbell affiliate. Manufacturing and compatibility certifications commonly cited include ANSI, CSA, IEEE, OSHA compliant, UL 506 listing with UL File E79947V1 and UL Insulation No B3223 credentials in catalog data for TB series transformers. \u003c\/p\u003e\u003c\/div\u003e","brand":"Acme","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656984199470,"sku":null,"price":381.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d2d1f696-df10-49d6-95d6-3306f01433d7.jpg?v=1769464945","url":"https:\/\/plgautomation.com\/products\/acme-electric-tb81005-industrial-power-transformer","provider":"PLG Automation ","version":"1.0","type":"link"}
