{"product_id":"fan-speed-controller-400volt","title":"Fan Speed Controller","description":"This is the 6 Ampere model from the well-known STR-4 series of speed controllers, which includes models ranging from 1.5 to 14 A. The STR-4 allows you to control the speed of your three-phase fan. Thanks to autotransformer technology, it delivers a well-regulated output voltage to your fan, ensuring smooth motor operation and extending the fan's lifespan. Using the external rotary knob on the device, you can select from 5 speeds. An additional 230 VAC output is provided as soon as the rotary knob is turned from the zero position. This can be used to connect, for example, a damper or an operational status indicator lamp.","brand":"GOG Gastro","offers":[{"title":"4 \/ 400V","offer_id":52667567931735,"sku":"TM3-4","price":802.0,"currency_code":"EUR","in_stock":true},{"title":"6 \/ 400V","offer_id":52667567964503,"sku":"TM3-6","price":1003.0,"currency_code":"EUR","in_stock":true},{"title":"11 \/ 400V","offer_id":52667567997271,"sku":"TM3-11","price":1416.0,"currency_code":"EUR","in_stock":true},{"title":"14 \/ 400V","offer_id":52667568030039,"sku":"TM3-14","price":1790.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0912\/5308\/0407\/files\/sentera-380.jpg?v=1769674507","url":"https:\/\/goggastro.com\/products\/fan-speed-controller-400volt","provider":"GOG Gastro","version":"1.0","type":"link"}
