You can purchase a power source to supply power to the GL and LTM450 circuits from www.jameco.com or other vendor that  you may know of. Look for a 12 volt DC source rated for at least 1 amp.

If it has a connector on the end you will need to cut it off and strip back the leads, tin them, and identify the plus and minus leads for connecting to the terminal strip. (If you have any questions, email or call for help).
