The AC input power supply module is an autoranging unit that supports input voltages between

100 and 240 VAC. The AC power supply module ships with a power cord to connect to an AC power outlet.

The DC input power supply module has a single input feed and supports input voltages from 18 to

32 VDC or 36 to 72 VDC. The DC power supply module ships with a terminal block to be wired for DC power outlet connections. The terminal block is covered by a clear plastic block cover that snaps onto the terminal block. You must remove the block cover before you work with the wires. The block cover is slotted so that the wires can exit only one end. If you want the wires to exit in a different direction, remove the block cover, rotate it, and snap it back on.
