This transformer provides stable low-voltage power to control circuits in HVAC, industrial, and commercial electrical systems. It is built for demanding environments where reliable voltage conversion is critical to system operation. Licensed electricians and HVAC technicians install this unit as part of control panel builds, rooftop unit wiring, and building automation system power supplies.\u003c\/p\u003e\u003cp\u003eThe E250D is suited for commercial and light industrial applications where 24-volt control circuits must be powered from 240-volt or 480-volt branch circuits. Typical installations include air handling units, packaged rooftop systems, motor control centers, and industrial control panels. Its 250 VA capacity supports multiple control loads simultaneously, making it appropriate for larger or multi-zone systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e250 VA transformer capacity supports multiple simultaneous control circuit loads\u003c\/li\u003e\n\u003cli\u003eDual primary voltage input accepts 240 or 480 volts for flexible installation\u003c\/li\u003e\n\u003cli\u003e24-volt secondary output compatible with standard low-voltage control circuits\u003c\/li\u003e\n\u003cli\u003eHeavy-duty construction rated for commercial and industrial environments\u003c\/li\u003e\n\u003cli\u003eCompact enclosure fits standard control panel and unit-mounted applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation control transformer for 24-volt control circuits powered from 240-volt or 480-volt branch circuits in commercial HVAC and industrial control applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this transformer should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Disconnect and lock out all power to the circuit before beginning any wiring work. Verify primary voltage selection matches the available branch circuit voltage before energizing. Secure the unit in a code-compliant enclosure and confirm all secondary circuit loads do not exceed the 250 VA rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 250 VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Voltage\u003c\/strong\u003e: 240 x 480 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78347253114\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: APPLETON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E250D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APPLETON","offers":[{"title":"Default Title","offer_id":51383733059890,"sku":"E250D","price":316.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675611.jpg?v=1782605783","url":"https:\/\/voomisupply.com\/products\/appleton-e250d-control-transformer-250va-240x480-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
