It is the genuine Jandy part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe AquaLink control side runs on 24VAC, not on line voltage. The transformer is what makes that step down, so it sits between the incoming 120VAC supply and everything the automation system actually controls. Without it, nothing in the panel powers up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA dead transformer presents the same way as a dead controller: no display, no relays clicking, nothing responding. Before replacing a control board, check for 24VAC on the transformer output. It is a far cheaper part and a far more common failure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is line voltage work inside an automation enclosure and belongs to a qualified electrician or service technician, with power isolated at the breaker before the panel is opened.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48626853183700,"sku":"JDY-301-5081","price":172.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_4f8d00b6-4eb4-4e12-ae65-f2112cece245.jpg?v=1788715852","url":"https:\/\/www.activepoolsupply.com\/products\/transformer-120vac-24vac","provider":"Active Pool Supply","version":"1.0","type":"link"}
