I can’t seem to find anyone that sells anything with a plug that fits. Thanks in advance! January 2, 2017 at 1:49 pm #2549 Davide ManciniKeymaster Hi there! Any 12 to 24Vdc 2A adapter will do. You just need to check the polarity and type of the barrel: DC jack 5.5mm / 2.2mm (internal), central positive Regards, Davide Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
