Updates To MaxxAir Replacement Printed Circuit Board # MA10A21275K Version C

Question

Question:

Do these boards, which I assume is the C version now have built in voltage protection. And do they now come with any type of conformal coating now to protect against moisture damaging them. Thanks

I reached out to MaxxAir for the Replacement Printed Circuit Board # MA10A21275K and any updates. The current C version has been updated with better resistors to better regulate both voltage and amperage. It does include a coating for corrosion resistance from moisture on the board itself. Be sure to use Dielectric Grease # LT37534 on the connectors since they are not coated otherwise it would interfere with the connection.
