NV30 12 volt A AUI supply failed

Post by mbrockm »

Got a notification from my NV30 that the 12 volt A AUI supply failed. I waiting for a response from Nautel support. Can someone tell me before I go to the site where this supply is and what is being affected by it's failure. I was guessing by the description it was the local AUI screen since the remote AUI screen is working fine.

Not 100% sure about a NV30, but in the NV20 these power supplies are located right down the bottom of the transmitter.

There are 2 supplies and they normally operate in parallel, so a loss of one supply is a loss of redundancy. They are pretty standard off-the-shelf PSU's made by MeanWell (AFAIK).

The local AUI and remote AUI are both handled by the same computer, so if remote is working so is local :)

Thanks. I thought they were in parallel. Odd they mark one 12 volt supply AUI and the other 12v SBC

Anyone know the amperage on these 12 volt supplies. Waiting for Nautel to ship. But like to get a spare on the shelf.

If you look in the manual..

.. the part no for the supply is SP-200-12, made by MeanWell.

Data for that PSU is here which indicates it can supply a max of 16.7A.

Also looks like that supply is end-of-life and is replaced by the RSP-200-12, which is also a 200W supply but slightly different form-factor. DigiKey has them for about $50.

No problems. The manuals are also available from the Nautel site, and are often updated as new firmware is released.
