ThinkGrow OPA-2 Smart Junction Box

The ThinkGrow Smart Junction Box 2 (OPA-2) is an electronic circuit breaker and energy meter designed to monitor and control electrical parameters such as voltage, current, power, and power factor. 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 enables users to set parameter values for Lines 1 and 2 in Light Group Control Groups 0-9 and 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 accurate 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.
