The 39177 converts 100 to 240 Vac to a regulated 24 Vdc. The 39177 comes standard with a USA/Canada plug, with an option to add a kit for international use. On one end, the 39177 has a plug that inserts into a wall socket. There are several cable termination options for the other end of the cable.  Note: When the 39177 is used as a power source for the CH200, PS200, or CH201, the charge controller needs to be configured to match the incoming current so it doesn't trip the over-current protection of the 39177.
