Meanwell RSP-200-48 P/S noise

[Claudio]

Hello everyone,

I just finished my amplifier (Jim’s MRF-101) this weekend and have been using a TDK-Lambda LS100-48 switched power supply, which is very quiet, no noticeable RFI on my SDR transceiver. However, this PS is only rated to 2.3A and the PS trips when the amp goes beyond 60 Watts. Does anyone have used the Meanwell RSP-200-48.

Thanks,

Claudio !!

I am using the RSP-200-48 for my MRF101 PA with the low pass and SWR/ switching boards and don't  see any RFI from 80m to 10m (did not test 160m or 60m).

Thanks Joerg,

I can confirm, this power supply is quiet. I did not see any RFI from 80 to 10 meter bands. Did not check on 160 meters. I do not operate on this band.
