Description
The OPA-2 is a smart junction box that powers a string of daisy-chained ThinkGrow LEDs and watches the circuit. It meters voltage, current, power and power factor, cuts power to the lights if current climbs past the limit you set, and connects to TrolMaster controllers for remote monitoring, light grouping and dimming.
