A6Z-48-30 Power Supply","description":"\u003cdiv\u003e\u003cp\u003eThe Avatar Instruments A6Z-48-30 is a three‑phase, three‑leg SCR power controller designed for 120–480 VAC line voltages and rated for 30 A, capable of delivering 0–99% of the applied line voltage to directly connected electric heaters or similar loads. It accepts a 4–20 mA control signal at 10 V DC and offers optional remote on\/off signaling via -R120 (120 VAC) or -R32 (10–32 V DC). Cooling options include convection for 30–80 A loads and fan cooling (120 VAC) for higher duty loads, with a thermostat set at 190°F for fan‑cooled configurations. Electrical characteristics specify an input impedance of 500 ohms, and the unit is wired with 10 AWG copper leads and lug hardware rated for 10 AWG; typical net weight is about 7 lb (shipping weight around 9 lb) and lug torque is 35 lb‑in. The device operates from 120 to 480 VAC at 50\/60 Hz, and power dissipation is 3.6 times the maximum current (watts), reflecting its proportional SCR firing for precise control of heating or process loads. This model is part of Avatar Instruments’ A6Z SCR power controller family, with other load ratings such as 40, 60, 80, and 100 A available in the same series and a similar 120–480 VAC design, ensuring compatibility across a range of industrial heating applications. \u003c\/p\u003e\u003c\/div\u003e","brand":"AVATAR","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46274343338218,"sku":null,"price":215.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-075.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/avatar-instruments-inc-a6z-48-30-power-supply","provider":"GTG Hardware","version":"1.0","type":"link"}
