English term or phrase: contact wetting power supply
Burtiski tulkojot sanāk mitrinošais, bet tas neapmierina. Kaut kā pārāk asociējas ar slapināšanu. Kādi piedāvājumi?

Izskaidrojums, kas ir wetting:
It is any supply supplying more than about 10ma. closed circuit. Or applying more than a few volts open circuit. Currents/voltages less than this are considered "dry switching" because there is insufficient energy to punch through the oxide films common to for example tin and silver contacts. Contacts for "dry switching" are often plated with gold or other noble metals that grow little or no oxides/sulfides, etc.

People tend to break these rules all the time switching small signal voltages with power contacts, etc. These same folks have a lot of "relay trouble". Specifying a contact wetting power supply is just a way to make sure there is enough energy available for reliable switching. Wetting the contacts, in this context, is simply breaking up the oxide films with a tiny bit of arcing.

Explanation:
Ņemot vērā, citu kolēģu http://www.proz.com/kudoz/english_to_turkish/computers_gener... apspriesto un vēl klejojumus internetā nonācu pie šī varianta. http://www.delfi.lv/auto-tehnika/dazadi/uz-jauna-e-papira-va... (kā atsaucei gan nav autora un ticamība delfi nav liela, bet vismaz pieminēts).

Faktiski varētu būt pat slapināšana pēdiņās, jo konkrētāk pats process ir strāvas pievadīšana, http://www.tezaurs.lv/sv/?w=slapināšana
