U3V70F12 to activate mercury relay

I am trying to activate the coil on a mercury relay using the U3V70F12. Coil data listed below

  • Coil Data
    • 28 Ω
    • 433 mA
    • 5.2 VA
    • 5.2 Watts

3.3v input and when connected to the relay coil it only outputs 4.4 v 180 mA.

When I connect it to a solid state relay it outputs 12.2v 40mA.

Is there anything I can do to get it to activate the mercury relay?

Could you post more information about your relay, preferably including a link to the specifications or product page?

What are you using as your 3.3V input voltage source, and more specifically, how much current can it source? Have you tried measuring the input voltage when your system is powered to see if it stays steady at 3.3V or drops (which would indicate an inadequate power source)?

Also, could you post some pictures of your setup that show all of your connections?
