Open Frame Power Supply with 5v @5.5a, 12v @2.5a, -12v @ .5a outputs. 100 to 240VAC input. This is also a good (Higher Current) replacement for the Bally s5500 slot power supply, just reverse the housing on the AC input to match the harness. Ask us, we will do it for you before shipping. Outputs the same and ratings are higher. Bolts in perfectly.
