It accepts 480 V AC (three-phase) input and provides a DC field current rated up to 25 A, with a corresponding field voltage up to approximately 380 V DC; the input current rating is up to 35 A AC. The unit incorporates surge protection via MOVs and a heat-sink design to support continuous operation at the rated current, with FS2\/4 documentation confirming 25 A DC output for the FS?-25-4 variant and 15 A DC for standard models in the same family. Typical applications include precise field current regulation for DC motors in industrial machinery, backup drive configurations, and situations where a standalone field regulator is employed with DC drives or controllers.\u003c\/p\u003e\u003c\/div\u003e","brand":"SAF","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51710992777518,"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_e9fc28d5-703a-407a-a20c-96ce5baf6c9e.jpg?v=1770320818","url":"https:\/\/plgautomation.com\/products\/saf-fs2-25-4-dc-drive-field-regulator","provider":"PLG Automation ","version":"1.0","type":"link"}
