Power Werx S5-30DV Switching P/S "Heads Up"
Locked
 
|
I recently acquired two Power Werx S5-30DV Switching Power Supplies.
While the P/S are nice and small, work on 110 / 220 and easily powered my K-3 and TS-480, BEWARE... The P/S come from the factory set for 220V (Slide Switch Selection on the back) The documentation sheet with the P/S doesn't mention the factory default setting of 220. If you power a K-3 or most likely any other rig without changing the input voltage setting to 110 if you run the P/S on 110 and don't change the input voltage switch to 110, you will have terrible AC on transmit when the RF level of the radio is increased over 10 Watts. 73, Jack W0UCE ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I recently purchased the SS-30DV switcher. There are 2
stickers on the outside of the box that say it is an International Model and you need to change it to 115V AC input by sliding the selector on the back.The manual (one sheet) clearly states in the first sentence of a paragraph titled "Input Voltage Selection" that "The power supply is set up for 230V AC input as shipped from the factory." It continues with a description about how to change it to 115V AC. I can't find it now, but I'm sure there was also a separate insert on bright paper warning that it was set for 230V AC. 73, Ken K3IU ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ On 9/12/2011 9:21 PM, W0UCE wrote: > I recently acquired two Power Werx S5-30DV Switching Power Supplies. > > > > While the P/S are nice and small, work on 110 / 220 and easily powered my > K-3 and TS-480, BEWARE...

YEP....I was one of the very first t order the 'International' version when first released. When I called they did not have stock but expected their first shipment in the coming week so I odered two (2) of them.
Both units are in daily use and have never let me down...oh no, I should not have siad that huh? I have also not noticed any birdies or RF hash with either unit and for me the small footprint has been a proven winner. 73 Gary VK4FD - Motorhome Mobile Elecraft Equipment K3 #679, KPA-500 #018 Living the dream!!! ----- Original Message ----- From: Ken K3IU To: W0UCE Cc: [hidden email] Sent: Tuesday, September 13, 2011 7:59 PM Subject: Re: [Elecraft] Power Werx S5-30DV Switching P/S "Heads Up" I recently purchased the SS-30DV switcher.
