This is a variable voltage power supply. Input is 110V or 220V AC + 20%, set by switch. Output is 0 - 12 VDC at 30A.
To use this power supply for large Total Control Lighting projects, set the AC in to 110V or 220V, adjust the DC out voltage screw to 5V, attach a male barrel connector to each of the three pairs of tabs, and attach a Y barrel connector to each of the three male barrel connectors. Each Y barrel connector will feed 10A of power to the pixels through two Power-T Connectors.
PLEASE NOTE: The user must set adjustments, provide his or her own AC power cord, and attach whatever connector is chosen for the DC out.
