As part of Avel's D4000 Standard Range toroidal lineup, this unit delivers two isolated 18 VAC windings in a compact package, and it uses dual primary windings to support 50\/60 Hz mains with the primaries connectable in series or parallel to match 115\/230 V. The secondary voltage tolerance is within 3% at normal input and full load, providing stable rails for sensitive electronics. Mounting is via a metal dish with two foam pads, and the hardware (bolts, washers, and nuts) is included. Physical dimensions list roughly 2.78 inches (≈91 mm) in diameter and about 1.8 inches (≈45 mm) in height, with a body mass around 4.5 kg, making it a sturdy yet compact choice for power-supply projects requiring dual 18 VAC rails.\u003c\/p\u003e\u003c\/div\u003e","brand":"AVEL","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46274168258794,"sku":null,"price":44.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-074.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/avel-lindberg-at-d4022-transformer","provider":"GTG Hardware","version":"1.0","type":"link"}
