In addition to regulating the generator voltage, the circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator. Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the it. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +\/- 1.5%.\u003cbr\u003e\u003c\/span\u003e\u003cspan class=\"td\"\u003e\u003cspan\u003e\u003cspan lang=\"EN-US\"\u003e6GA2 491-1A \u003c\/span\u003e调压板用于西门子和现代\u003cspan lang=\"EN-US\"\u003e1FC6\/HFC6\u003c\/span\u003e发电机输出电压的控制。\u003cbr\u003e\u003cspan lang=\"EN-US\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"td\"\u003e\u003cspan\u003e基本原理是相复励可控硅励磁分流，调节励磁机的励磁电流\u003cspan lang=\"EN-US\"\u003e\/\u003c\/span\u003e电压以达到不同负载状况下稳定发电机输出电压的目的。\u003cbr\u003e\u003cspan lang=\"EN-US\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"td\"\u003e\u003cspan\u003e使用这种调压系统的发电机可提供±\u003cspan lang=\"EN-US\"\u003e5% \u003c\/span\u003e的电压调节范围以及±\u003cspan lang=\"EN-US\"\u003e 0.5% \u003c\/span\u003e的电压调整率。而且具有很强的抗突加突卸的能力。\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Shinhang Marine","offers":[{"title":"Default Title","offer_id":48880145498354,"sku":null,"price":1.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/2286\/4626\/files\/Lad8N02-2026-03-18T183732.398.png?v=1773830346","url":"https:\/\/shinhangmarine.net\/products\/siemens-cm-hyundai-voltage-regulator-avr-6ga2-491-1a","provider":"Shinhang Marine","version":"1.0","type":"link"}
