0-10V, PWM, TRIAC Dimmable LED panel
... Another difference from SCRs is that TRIACs can be triggered by either a positive or a negative current applied to its gate electrode, whereas SCRs can be triggered only by currents going into the gate. In order to create a triggering current, a positive or negative voltage has to be applied to the ...

... Diagram "C" will handle the most fixtures by creating a parallel loop that is powered from the center or both sides As with any wiring, voltage and current loss will occur as home run lengths increase and LED fixtures get further away from the power supply. The gauge of wire used plays a major role ...

An Introduction to Electrical Power for the Non-Power
... Direct current means that current always flows in one direction and is the simplest type of circuit to grasp for reasons we’ll cover soon. Alternating current means the voltage and current are sine waves that change direction (flow) or oscillate continuously. In North America this typically happens ...
