This 550 kVA unit features a 208V delta primary connection and 480Y\/277V wye secondary configuration, operating at 60Hz frequency with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R\/IP24 enclosure with ANSI 61 grey finish, measuring 59\" H × 48.5\" W × 38\" D, and produces a maximum sound level of 62 dBA. It complies with IBC 2018 seismic standards (Sds=2.0, z\/h=0, lp=1.5) and carries approvals for installation in both US and LATAM markets. Typical applications include industrial plants, commercial facilities, and utility distribution systems requiring reliable power transformation.      \u003cb\u003eKey Features \u0026amp; Specifications\u003c\/b\u003e  \u003cul\u003e \u003cli\u003eType: Three-Phase General Duty Transformer\u003c\/li\u003e \u003cli\u003eVoltage: 208V Delta Primary \/ 480Y\/277V Secondary\u003c\/li\u003e \u003cli\u003eCurrent: 550 kVA Capacity\u003c\/li\u003e \u003cli\u003eFrequency: 60Hz\u003c\/li\u003e \u003cli\u003eMaterial: Aluminum Windings\u003c\/li\u003e \u003cli\u003eTemperature Rise: 150°C\u003c\/li\u003e \u003cli\u003eInsulation Class: 220°C\u003c\/li\u003e \u003cli\u003eImpedance: 4.5% - 7% Standard\u003c\/li\u003e \u003cli\u003eEnclosure: Type 3R \/ IP24, ANSI 61 Grey\u003c\/li\u003e \u003cli\u003eDimensions: 59\" H × 48.5\" W × 38\" D\u003c\/li\u003e \u003cli\u003eSound Level: 62 dBA (NEMA ST-20)\u003c\/li\u003e \u003cli\u003eSeismic Compliance: IBC 2018 (Sds=2.0)\u003c\/li\u003e \u003cli\u003eVector Configuration: YNd1 (-30°)\u003c\/li\u003e \u003c\/ul\u003e \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: DM550BK\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Hammond Power Solutions\u003c\/li\u003e\n\u003cli\u003eBrand : Hammond Power Solutions\u003c\/li\u003e\n\u003cli\u003eCategory : Transformer\u003c\/li\u003e\n\u003cli\u003ePhase : 3\u003c\/li\u003e\n\u003cli\u003eEnclosure Grade : Standard\u003c\/li\u003e\n\u003cli\u003eDuty : General Duty\u003c\/li\u003e\n\u003cli\u003eFrequency : 60Hz\u003c\/li\u003e\n\u003cli\u003ePrimary Voltage : 208D\u003c\/li\u003e\n\u003cli\u003ePrimary Connection : Delta\u003c\/li\u003e\n\u003cli\u003ePrimary FCAN (NPL) : 1x5.5%\u003c\/li\u003e\n\u003cli\u003ePrimary FCBN (NPL) : 1x5.5%\u003c\/li\u003e\n\u003cli\u003eSecondary Voltage : 480Y\/277\u003c\/li\u003e\n\u003cli\u003eSecondary Connection : Wye-N\u003c\/li\u003e\n\u003cli\u003eMaterial : Aluminum\u003c\/li\u003e\n\u003cli\u003eTemperature Rise : 150°C\u003c\/li\u003e\n\u003cli\u003eInsulation Class : 220°C\u003c\/li\u003e\n\u003cli\u003eEKVA : 550\u003c\/li\u003e\n\u003cli\u003eEfficiency Regulation : No Efficiency Specification;
