Commonly installed in control panels, HVAC equipment, manufacturing machinery, and electrical distribution systems where stable 120 VAC control power is required. Maintenance teams, electricians, and OEMs use this transformer for panel builds, equipment repairs, control system upgrades, and replacement of failed power transformers in legacy or modern industrial systems. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eApplications:\u003c\/h3\u003e\n\u003cp\u003eThe Dongan 500250053 Transformer is designed for converting primary voltages (commonly 240\/480 VAC) down to 120 VAC control power for industrial control circuits. It is widely used in motor control panels, PLC systems, HVAC controls, machine tools, and industrial automation equipment where isolation and stable control voltage are required for safe operation of relays, contactors, and instrumentation. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp\u003e• Manufacturer: Dongan Electric Manufacturing\u003cbr\u003e• Model \/ Part Number: 500250053\u003cbr\u003e• Product Type: Control Power Transformer\u003cbr\u003e• Phase: Single Phase\u003cbr\u003e• Primary Voltage: 240 \/ 480 VAC\u003cbr\u003e• Secondary Voltage: 120 VAC\u003cbr\u003e• Power Rating: 0.25 kVA (approx. 250 VA)\u003cbr\u003e• Frequency: 50\/60 Hz\u003cbr\u003e• Mounting: Panel \/ Enclosure mount\u003cbr\u003e• Cooling: Air cooled (natural convection)\u003cbr\u003e• Construction: Encapsulated \/ industrial control transformer\u003cbr\u003e• Application: Industrial control circuits, PLC panels, motor control systems\u003cbr\u003e• Operating Environment: Industrial electrical enclosures\u003cbr\u003e• Isolation: Electrical isolation transformer\u003c\/p\u003e\n\u003ch3\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp\u003e• Hammond industrial control transformer (240\/480 → 120 VAC, 250 VA class)\u003cbr\u003e• Square D control power transformer (0.25 kVA class)\u003cbr\u003e• Siemens SITOP \/ control transformer equivalents (application d\u003c\/p\u003e","brand":"PLG Automation ","offers":[{"title":"New","offer_id":51727604580654,"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_cf4a4cdb-fa4b-4d1a-9c10-73a6af4bb62a.jpg?v=1770583434","url":"https:\/\/plgautomation.com\/products\/dongan-500250053-transformer","provider":"PLG Automation ","version":"1.0","type":"link"}
