It continuously monitors the insulation resistance of AC\/DC main circuits up to 300 V. When an insulation fault occurs, the device triggers an alarm, allowing the first earth fault to be detected before a second fault causes a power outage or equipment damage. The device complies with IEC 61557‑8 and is suitable for both AC and DC unearthed systems.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eTechnical Specifications\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Response value: 40 kΩ (fixed)\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Rated system voltage: AC\/DC 0…300 V, 15…400 Hz\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Supply voltage: AC 230 V, 50…400 Hz\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Power consumption: 3.0 VA\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Relay contact rating: AC 250 V \/ 5 A\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Data sheet: K1.1\/11.1-1\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eKey Features\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Insulation monitoring: Continuously monitors the insulation resistance of the IT system to earth; fixed response value of 40 kΩ.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Alarm output: Alarm relay activates when the insulation value falls below the set threshold.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· LED status indication: Front‑panel LEDs clearly indicate device operating status and alarm condition.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Connection monitoring: Continuously monitors the measuring leads and earth connection to ensure measuring circuit integrity.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Self‑test and reset: Supports local manual testing and reset for easy on‑site maintenance.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eTypical Applications\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Industrial IT systems (AC\/DC unearthed systems)\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Online insulation monitoring of mobile generators\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Unearthed control circuits in control cabinets and machinery\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Lighting systems, building electrical installations\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· DC distribution systems\u003c\/span\u003e\u003c\/div\u003e","brand":"Bender","offers":[{"title":"Default Title","offer_id":44194316025944,"sku":null,"price":343.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0580\/2799\/9320\/files\/IR145R-4.....jpg?v=1780710226","url":"https:\/\/gexufein.com\/products\/bender-ir140y-4-300v-10-200kohm-insulation-monitor-for-ac-it-systems","provider":"Gexufein Automation","version":"1.0","type":"link"}
