Hello Community,

I'm attempting to repair the SMPS on a Levoit 600S air purifier. The transformer is likely open. It has six pins. 2 pairs on the primary side (one pair tested open) and 1pair of legs on the secondary side. Legs on the secondary side are spread wide apart (end-to-end). I've circled them in blue. Dimentons of the transformer are 22x23mm. Marking on the transformer are EE16 1.9mH-B. Fuse for the powerboard is fuse 250V 3.15A. I've been unable to find an exact match and I'm hoping for some help here to find a suitable replacment.

Peace
LM
