It accepts 120 or 240 volt input and delivers 12 or 24 volt boost or buck output at 60 Hz, allowing installers to raise or lower line voltage by a fixed increment without replacing larger upstream equipment. The unit carries a NEMA 3R enclosure rating, making it suitable for both indoor and outdoor installations. RoHS compliant construction is standard. Licensed electricians and electrical contractors are the primary installers for this device.\u003c\/p\u003e\u003cp\u003eBuck boost transformers like the 1.5S43F are commonly used in light commercial, industrial, and utility applications where supply voltage falls slightly outside acceptable equipment tolerances. Typical scenarios include correcting voltage drop on long feeder runs, matching motor nameplate voltages to available service, and supporting low-voltage control circuits. The NEMA 3R rating allows installation in outdoor enclosures or locations exposed to rain and weather, expanding deployment flexibility on job sites where service entrance or distribution equipment is mounted externally.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.5 kVA power rating handles typical small voltage-correction loads in commercial and light industrial settings\u003c\/li\u003e\n\u003cli\u003e120 x 240 volt input accommodates standard single-phase service configurations\u003c\/li\u003e\n\u003cli\u003e12\/24 volt output enables precise buck or boost voltage adjustments\u003c\/li\u003e\n\u003cli\u003eNEMA 3R enclosure rating approved for indoor and outdoor installation\u003c\/li\u003e\n\u003cli\u003eSingle-phase, 60 Hz design matches standard North American power distribution\u003c\/li\u003e\n\u003cli\u003eRoHS compliant materials meet international hazardous-substance standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use single-phase buck boost transformer for applications requiring small voltage correction on 120 or 240 volt single-phase circuits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before making any connections to the transformer. Verify input voltage and output voltage configuration match the intended application before energizing. The NEMA 3R enclosure provides rain protection but does not seal against submersion or direct water spray, so mounting location should account for proper drainage and clearance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rating\u003c\/strong\u003e: 1.5 kVA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage\u003c\/strong\u003e: 120 x 240 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage\u003c\/strong\u003e: 12\/24 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1 Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA 3R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Environment\u003c\/strong\u003e: Indoor and Outdoor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 9.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 11.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 37.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1.5S43F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51539023593778,"sku":"1.5S43F","price":1714.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/150c48fd9ea3634e052c5ce18680c6f3_d26b9e9c-7a11-4277-81a6-2f6128f41785.jpg?v=1785833136","url":"https:\/\/voomisupply.com\/products\/square-d-1-5s43f-buck-boost-transformer-1-5-kva-nema-3r","provider":"Voomi Supply","version":"1.0","type":"link"}
