{"product_id":"abb-ach550-uh-012a-4","title":"ABB ACH550-UH-012A-4","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe ABB ACH550-UH-012A-4 is a 7.5 HP variable frequency drive purpose-built for HVAC applications, delivering 11.9 amps of continuous output on 380–480V three-phase power. Housed in a wall-mount UL Type 1 enclosure (R1 frame), this ACH550 series drive is a proven workhorse for supply and return fans, air handling units, cooling tower fans, and centrifugal pumps in commercial buildings.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBuilding automation integration comes standard: the ACH550-UH-012A-4 includes embedded BACnet, Modbus RTU, Johnson Controls N2, and Siemens FLN protocols with no add-on communication cards required. Two internal PID loops, a real-time clock with timer functions, and preloaded HVAC application macros make commissioning fast, while the Hand-Off-Auto keypad gives operators familiar, intuitive control. ABB's patented swinging choke reduces harmonic distortion without external line reactors.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eABB has discontinued the ACH550 series in favor of the ACH580, but thousands of ACH550-UH-012A-4 drives remain in service. We keep this model in stock — fully tested and warrantied — so you can replace a failed unit without reprogramming your BAS or rewiring for a new drive family. Board-level repair and exchange options are also available, and if you're ready to modernize, we can cross-reference the direct ACH580 replacement.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eManufacturer: ABB\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSeries: ACH550 (HVAC drive)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHorsepower: 7.5 HP (normal duty)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOutput current: 11.9 A continuous\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInput: 380–480 V AC, 3-phase\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEnclosure: UL Type 1 (IP21), frame size R1\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCommunications: BACnet, Modbus RTU, Johnson Controls N2, Siemens FLN (embedded)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLifecycle status: Discontinued by ABB — superseded by ACH580 series\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"New","offer_id":46179401662700,"sku":"ACH550-UH-012A-4-FS","price":5703.81,"currency_code":"CAD","in_stock":true},{"title":"IAC Certified Refurbished","offer_id":47470268874988,"sku":"ACH550-UH-012A-4-R","price":1701.14,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/abb-drives-ach550-uh-012a-4-new-270.jpg?v=1780927331","url":"https:\/\/www.industrialautomationco.com\/en-ca\/products\/abb-ach550-uh-012a-4","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
