It measures accumulated energy plus instantaneous voltage, current, active and apparent power per phase in real time, supporting 4-quadrant measurement for imported and exported energy (e.g. solar). It connects via Wi-Fi, Bluetooth and LAN and supports Modbus TCP for integration into industrial or home energy-management systems.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable border=\"1\" cellpadding=\"4\" cellspacing=\"0\" style=\"border-collapse:collapse;width:100%\"\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSHELLY PRO 3EM-120A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShelly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSmart Home\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eKey Specs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3-phase (or 1-phase) energy meter, DIN-rail mounted; Ships with 3x 120A split-core current transformers; Measurement accuracy: 1%, Accuracy class B (active energy, IEC 62053-21); Connectivity: Wi-Fi, Bluetooth, LAN; Data logging: at least 45 days at 1-minute resolution (local); Protocols: Modbus TCP, MQTT, WebSocket (in\/out), UDP, mTLS; 4-quadrant measurement (import\/export)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Shelly","offers":[{"title":"Default Title","offer_id":49954604613861,"sku":"SHELLY PRO 3EM-120A","price":4109.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0010\/6725\/files\/Shelly-Pro-3EM-120-main-image_db4e0c04-4467-4527-af27-15ebf47e0b37.png?v=1783409569","url":"https:\/\/guardsondutyshop.co.za\/products\/shelly-shelly-pro-3em-120a","provider":"Guards On Duty Shop \u0026 Security Guards ","version":"1.0","type":"link"}
