The LS520, LS520A, and LS520A-RH were highly prized as the workhorses of Taiyo Yuden inverters and it's two big transformer blocks were nearly ubiquitous in industrial and medical designs that utilized an LCD with a dual-CCFL backlight (a large reason why they continued the same part number scheme through multiple iterations).

We were fortunate enough to come across stock of over 1,000 of these, brand new and factory sealed.

If you need some for ongoing production or just to repair a one-off device, we're happy to help!
