Equipped with overcurrent protection functionality, users can set three levels of overcurrent protection points. With built-in overcurrent protection and compatibility with TrolMaster controllers, the OPA-2 allows remote monitoring and adjustment of settings for optimal performance. The OPA-2 allows users to set parameter values for Line 1 and Line 2 in Light Group Control Groups 0-9, as well as for UV, White, Deep Red, and Far Red in Spectrum Group Groups 0-9. This functionality enables precise control over the illumination levels of the lighting strips Featuring RS-485 communication, it supports precise control of lighting systems and offers unparalleled reliability and durability. If the circuit protector detects unusual high amperage, the power to the LEDs will be turned off to prevent damage to the LEDs and the Daisy Chain Power Cord System.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLighting fixture Grouping\u003c\/li\u003e\n\u003cli\u003eComplete power-off solution for night cycle\u003c\/li\u003e\n\u003cli\u003eOvercurrent Protection\u003c\/li\u003e\n\u003cli\u003ePower Surge Protection\u003c\/li\u003e\n\u003cli\u003ePower Consumption Data Collection\u003c\/li\u003e\n\u003cli\u003eOn-Site Monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1 x Smart Junction Box (OPA-2)\u003c\/li\u003e\n\u003cli\u003e1 x Think\u003c\/li\u003e\n\u003cli\u003eGrow 12' Daisy Chain Control Cable (ECS-7)\u003c\/li\u003e\n\u003cli\u003e2 x 12ft RJ12 to 4-Pin IP65 Connector Cable (ECS-9)\u003c\/li\u003e\n\u003cli\u003e2 x Y- Splitter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInput power: 100~277VAC, 50\/60\u003c\/li\u003e\n\u003cli\u003eHz\u003c\/li\u003e\n\u003cli\u003eRated voltage: 100~277V\u003c\/li\u003e\n\u003cli\u003eRated current: 30A\u003c\/li\u003e\n\u003cli\u003eShut-off Point Range: 15A \/ 20A \/ 30A\u003c\/li\u003e\n\u003cli\u003eOvercurrent protection point: +120%\u003c\/li\u003e\n\u003cli\u003eSensitivity to protection: Response within 0.5s\u003c\/li\u003e\n\u003cli\u003eVoltage accuracy: ±2% readings／±1% shut-off point\u003c\/li\u003e\n\u003cli\u003eCurrent accuracy: ±2% readings／±1% shut-off point\u003c\/li\u003e\n\u003cli\u003ePower accuracy: ±5% readings／±1% shut-oft point\u003c\/li\u003e\n\u003cli\u003ePF accuracy: ±10%\u003c\/li\u003e\n\u003cli\u003eOperating temperature: 32~104°F\u003c\/li\u003e\n\u003cli\u003eWorking humidity: 5-95%RH\u003c\/li\u003e\n\u003cli\u003eCommunication Interface: RS-485\u003c\/li\u003e\n\u003cli\u003eCertifications: ETL \/ FCC\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTechnical documentation:\u003c\/strong\u003e \u003ca href=\"https:\/\/trolmasterfilese.s3.us-west-2.amazonaws.com\/ManualFiles\/ThinkGrow\/Accessories\/OPA-2\/OPA-2+Techsheet.pdf\" target=\"_blank\" rel=\"noopener\"\u003eView technical sheet\u003c\/a\u003e\u003c\/p\u003e","brand":"ThinkGrow","offers":[{"title":"Default Title","offer_id":62813945266506,"sku":"OPA-2","price":247.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1030\/5994\/7850\/files\/OPA-2_01.webp?v=1794080976","url":"https:\/\/thegrowfellas.com\/products\/thinkgrow-opa-2-100-277v-smart-junction-box","provider":"The Grow Fellas","version":"1.0","type":"link"}
