Commonly installed in industrial control panels, manufacturing equipment, machine tools, and factory automation systems where low-voltage control power is required from a higher-voltage three-phase supply. Maintenance teams, electricians, and OEMs use this transformer for equipment repairs, control panel retrofits, replacement of failed transformers, and restoration of legacy industrial systems. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eApplications:\u003c\/h3\u003e\n\u003cp\u003eThe Doesburg BV 4R793388 Transformer is designed for industrial applications requiring conversion of 500 VAC three-phase power to 24 VAC control voltage. It is commonly used in control cabinets, PLC systems, motor control centers, packaging equipment, and automated manufacturing lines where isolation and voltage reduction are necessary for relays, contactors, sensors, and other low-voltage control devices. The transformer is particularly suited for legacy European machinery and industrial automation equipment. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp\u003e• Manufacturer: Doesburg BV\u003cbr\u003e• Model \/ Part Number: 4R793388\u003cbr\u003e• Product Type: Three-Phase Control Transformer\u003cbr\u003e• Rated Power: 250 kVA \u003cem\u003e(marking reported by seller; may require verification as physical size appears smaller than a typical 250 kVA unit)\u003c\/em\u003e\u003cbr\u003e• Primary Voltage: 500 VAC\u003cbr\u003e• Secondary Voltage: 24 VAC\u003cbr\u003e• Number of Phases: 3 Phase\u003cbr\u003e• Frequency: 50\/60 Hz typical\u003cbr\u003e• Transformer Type: Isolation \/ Control Transformer\u003cbr\u003e• Cooling Method: Natural Air Cooling\u003cbr\u003e• Winding Type: Copper or Aluminum (manufacturer dependent)\u003cbr\u003e• Mounting: Panel or floor mount depending on enclosure configuration\u003cbr\u003e• Application Environment: Industrial control panels, machine tools, and factory automation systems\u003cbr\u003e• Weight: Approximately 12 lb (5.4 kg) as listed by surplus seller\u003cbr\u003e• Product Status: Legacy industrial transformer with limited publicly available documentation \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp\u003e• Schneider Electric Three-Phase 500V to 24V Control Transformer\u003cbr\u003e• Hammond Power Solutions 3-Phase Control Transformer\u003cbr\u003e• Siemens 3-Phase Industrial Control Transformer\u003c\/p\u003e","brand":"PLG Automation ","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51727624077614,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_40c22bba-dd41-4931-9168-64b2d51ba417.jpg?v=1770583499","url":"https:\/\/plgautomation.com\/products\/doesburg-bv-4r793388-three-phase-control-transformer","provider":"PLG Automation ","version":"1.0","type":"link"}
