It is designed for single‑phase AC and DC systems to monitor undervoltage (\u0026lt; U), overvoltage (\u0026gt; U), underfrequency (\u0026lt; f), and overfrequency (\u0026gt; f). Voltage measurement uses the true RMS (r.m.s.) method to maintain high accuracy even in harmonic‑distorted environments. This version requires an external auxiliary supply (AC\/DC 70…300 V). It features a multi‑function LC display and adjustable response delays and switching hysteresis to prevent nuisance tripping caused by start‑up transients or short voltage fluctuations.\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· Rated system voltage (Uₙ): AC\/DC 0…300 V, 15…460 Hz\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Supply voltage (Uₛ): AC\/DC 70…300 V, 15…460 Hz\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Power consumption: ≤ 4 VA\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Monitoring functions: Undervoltage, overvoltage, underfrequency, overfrequency\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Measurement accuracy: Voltage ±1.5% ±2 digits (50\/60 Hz), frequency ±0.2%\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Alarm outputs: Two independent SPDT changeover contacts, AC 250 V \/ 6 A\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Display: Multi‑function LC display showing real‑time voltage and frequency\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· LED indicators: Power On, Alarm 1, Alarm 2\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Adjustable parameters: Start‑up delay, response delay, release delay, switching hysteresis, fault memory\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Operating temperature: –25 °C … +55 °C\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Mounting: DIN rail, width 36 mm (2 modules)\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Protection class: Housing IP30, terminals IP20\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Connection: Push‑wire terminals\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Standards compliance: RoHS\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Order number: B73010002\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· True RMS measurement (AC+DC) for harmonic‑rich systems\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Two independent alarm relays, configurable N.O.\/N.C. and fault memory\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Adjustable time delays and switching hysteresis to prevent nuisance tripping\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Preset function: automatically sets basic parameters on first power‑up\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Measured value memory stores the value that triggered the alarm\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Continuous self‑monitoring, password protection, sealable transparent cover\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Built‑in test\/reset button\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· Voltage and frequency monitoring of single‑phase machines and electrical installations\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Earth fault monitoring in medium‑voltage systems via voltage transformers\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Monitoring of battery systems\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e· Switching machinery and equipment at specific voltage thresholds\u003c\/span\u003e\u003c\/div\u003e","brand":"Bender","offers":[{"title":"Default Title","offer_id":44150314893400,"sku":null,"price":600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0580\/2799\/9320\/files\/VME420-D-1.jpg?v=1779900547","url":"https:\/\/gexufein.com\/products\/bender-vme420-d-2-300v-15-460hz-voltage-monitoring-relay-for-ac-dc-systems-1","provider":"Gexufein Automation","version":"1.0","type":"link"}
