220V to 12VAC 5A EI Step-Down Transformer (Single Secondary)

الوصف

Overview 🔌 High‑current EI transformer converting 220–240 VAC to 12 VAC @ 5 A (≈60 VA). Single secondary (NOT 12‑0‑12) . Ideal for robust linear PSUs and motor/relay loads. Key Features ⭐ Primary: 220–240 VAC, 50/60 Hz Secondary: 12 VAC, 5 A Power: ≈60 VA Chassis mount EI core Detailed Specifications 📐 Parameter Value Notes Input 220–240 VAC 50/60 Hz Output 12 VAC @ 5 A Single secondary Power ≈60 VA Vrms × I Regulation Not specified Load‑dependent (assumption) Pinout & Wiring 🧰 Side Terminals Function Primary P1 – P2 220–240 VAC Secondary S1 – S2 12 VAC output Performance & Calculations 📊 No‑load DC after bridge: 12·1.414 − ~1.4 ≈ ≈15.6 V . Example capacitor for ΔV=1 V at 5 A: C ≈ 5/(2·50·1) = 50,000 µF (or larger). نظرة عامة 🔌 محول قدرة EI يُخرج 12 VAC عند 5 أمبير (≈60 VA) من 220–240 VAC . ثانوي مفرد (مش 12‑0‑12) .
