This 20 mF (0.02 F) unit is rated for 310 V DC and is offered as part of Baumüller’s BUK external capacitor family in Type Series 6 housings, with a maximum intermediate circuit voltage of 400 V DC. The charging current is limited by the basic unit, and the permissible charging time per capacitor unit is greater than 1 second, while discharge time exceeds 10 minutes. The standard version is 000, and the assembly is designed for an ambient operating range of 0 to 45 °C with a storage range of -30 to +70 °C. Energy storage during braking is approximately 640 Ws (calculated from C × (U2^2 − U1^2)\/2 with U1 = 310 V and U2 = 400 V). \u003c\/p\u003e\u003c\/div\u003e","brand":"Baumuller","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676756476206,"sku":null,"price":2478.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_00f0611e-f86b-473f-9f6e-bfb7e1181065.jpg?v=1769552990","url":"https:\/\/plgautomation.com\/products\/baumuller-buk622-31-20-high-voltage-capacitor-bank-module","provider":"PLG Automation ","version":"1.0","type":"link"}
