This was the only replacement converter I could find that looked like it would fit my Iota Load Center. Mine was a 30 amp load center, but couldn't find another 30 amp to replace it. I was hesitant to buy this one as the picture doesn't show a cable coming out of it like the original and there were screws on finned side of the original and the picture doesn't show any screw holes on the finned side. I took a chance and to my relief the cable was there. On removing the old one, I discovered there were no screw holes on the original either. The screws were forced into the gaps in the fins. I kept everything fused to 30 amps as a precaution and now the batteries charge once again when plugged into shore power. I am so happy!
