Five device variants provide adjustable thresholds via potentiometers, with measuring ranges including 10–30 V (35 V max permissible), 20–60 V, 50–150 V, and 120–300 V, while the measuring circuit accepts DC and 40–400 Hz signals. Power consumption is ≤ 3.5 VA, and the unit offers a rated insulation voltage of 320 V AC with protective separation between the supply and measuring circuits; it also features an integrated energy backup and a compact 45 mm enclosure. The alarm relay has two potential-free changeover contacts, and status indicators include a Power On LED and an Alarm LED. Typical applications include voltage monitoring of motor power supplies, standby and emergency power monitoring, and earth-fault monitoring in medium‑voltage installations via voltage transformers.\u003c\/p\u003e\u003c\/div\u003e","brand":"Bender","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46266645512426,"sku":null,"price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-073.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/bender-b93015510-voltage-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
