It accepts 120 or 240 volt input and delivers 12 or 24 volt boost or buck output at 60 Hz. Housed in a NEMA 3R enclosure, it is rated for both indoor and outdoor installation, offering protection against rain and sleet. Electricians install this unit where minor voltage corrections are needed — typically to compensate for voltage drop over long feeder runs or to bring supply voltage into acceptable range for sensitive loads. The unit is RoHS compliant.\u003c\/p\u003e\u003cp\u003eThis transformer suits residential and light commercial electrical applications where a small, fixed voltage adjustment is required. Typical scenarios include correcting low or high line voltage feeding motors, HVAC equipment, lighting circuits, or control circuits. Its compact form factor and weatherproof NEMA 3R rating make it practical for installations in mechanical rooms, rooftop equipment enclosures, or exterior panels where exposure to the elements is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.05 kVA power rating for small fixed-increment voltage correction applications\u003c\/li\u003e\n\u003cli\u003e120 or 240 volt input with 12 or 24 volt buck or boost output at 60 Hz\u003c\/li\u003e\n\u003cli\u003eSingle-phase design suitable for residential and light commercial systems\u003c\/li\u003e\n\u003cli\u003eNEMA 3R rated enclosure approved for indoor and outdoor use\u003c\/li\u003e\n\u003cli\u003eRoHS compliant construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install buck boost transformer for single-phase 120\/240 volt electrical systems requiring minor fixed voltage adjustment.\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). De-energize and lock out the circuit at the panel before making any connections. Buck boost transformers must be wired in an autotransformer configuration per the manufacturer wiring diagram — incorrect polarity or connection will result in incorrect output voltage. Verify input and output voltage requirements before energizing the circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rating\u003c\/strong\u003e: 0.05 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: Single phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 3R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.57 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: 50SV43A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542943007026,"sku":"50SV43A","price":395.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/150c48fd9ea3634e052c5ce18680c6f3_6e44d359-3498-45e2-8261-a8f06296b756.jpg?v=1785911807","url":"https:\/\/voomisupply.com\/products\/square-d-50sv43a-buck-boost-transformer-0-05-kva","provider":"Voomi Supply","version":"1.0","type":"link"}
