Just got this in the mail I am sure they have related items. We use with very good results Mean Well SD DC/DC products, for my Rb 8607 project I plan on using Traco Power https://www.maximintegrated.com/en/design/reference-design-center/ref-circuits/7055.html?utm_source=Eloqua&utm_medium=email&utm_content=REFDES1234&utm_campaign=FY20_Q3_2020_FEB_ALL-BU_AMER_EE-Mail_EN Bert Kehren

I usually pick these up when I find them, recap if needed and they're a cheap and easy way to get a supply.
