Do you use a marine UPS for CTD operations?

I work in a small team that does CTD profiling from a vessel. In the process of trying to replace our Uninterruptible Power Supply (UPS), I learnt that we were using the wrong UPS all along (we have a desk bound UPS) and should have been using a marine UPS.

Now I’m curious as to whether all other teams around the world use a marine UPS or do you guys just power your CTD from the vessel’s mains directly?

I am no electrician but from what I understand, desk bound UPS are not able to protect the sensitive seabird equipment from “rough” currents provided by the vessel’s generators. What’s needed is an online double conversion UPS designed to work in marine conditions (vibration, heat, humidity, salt exposure etc)

Can’t find anything about needing a UPS in SeaBird’s manuals either.

Background info: we use a SBE 19plusV2 CTD and SBE33 carousel deck.
