Still working fine!  Time owned: more than 12 months
I bought my Emtron EPS-20ST at the 2008 Dayton Hamfest. I've used it to power several HF and VHF radios, but mainly a ten-Tec Pegasus HF radio at full 100 watts out with no problems. It's never been affected by RF in the shack, nor does it produce any objectionable noises.
It has been a solid performer, silent, and totally trouble free.

NOISE and RF  Time owned: more than 12 months
I have used this power supply CE version purchased in Switzerland and used with 220v and 110v.
Different /P and mountain activity. Also used in HI7/hb9oab 5B4/ and other /vacations... with 110v and 220v I have always had big big problems (RF NOISE and also HEAT).
A lot of strong NOISE on all band, extinguished often him and went to protection using an IC706 as full power (90w). The RFs were to the origin of the problems.

During the PILUP also went to protection for heat after 30min of QSO from HI7/hb9oab, during these /vacations, leaving many unusable QSOs considering that I also had the conditioned air and the temperature environment of the shack was of 25 degrees...
For 100w RTX and pilup activity is not not not at all recommended.

Perhaps in the last versions it works better, but mine is all right only for some FM (V/U) rtx!

Absolutely silent  Time owned: more than 12 months
The capabilities of this switchmode power supply may be smaller than others, ok, but if you look for a really silent power supply which produces NO hash and NO birdies, here it is! Used ones are sold for around 130.00USD on hamfests. If you just want to supply dc to a simple 100W-SSB-transceiver and an electronic key and no further gadgets like modems or DSP-filters have to be powered, this power supply will be enough, for sure! ... and you dont hear what you dont want to hear. Buy it if you can get one and don't worry that it's a "switcher".
