Gossen Metrawatt external power supply NA4/500 & NA5/600
« on: March 03, 2021, 08:26:52 pm »
Hello,

Can anybody say which type of connector is used with these power supplies, and to shad some light on their characteristics?
I need an external power supply for my Metrahit 18C calibrator.

Damn Metrawatt, I new it is not a standard length. I just have ordered 15 and 16 mm jacks from aliexpress, I couldn't find any shorter.

The newer ones are even worse, 3 pronged unobtainium.

Can you say will it be a problem if 5V standard USB power supply is used instead of NA's 4,2V?

I can't say for sure. My 30M has a 5V/600mA  supply requirement.
