Blast from the TomsHardware past – Stress Test: Power Supplies Under Full Load

Posted by jpluimers on 2019/09/16

Blast form the past, as I just found out I had archived the (moved) pages where the original link wasn’t:

We put PC power supplies from 300 to 850 watts under continuous load to see if they can satisfy the power appetite of potent Athlon and P4 systems. Are they efficient and stable? Click into the THG Laboratory to find out!

Sources: the “Stress Test: Power Supplies Under Full Load” series:

The original page was not archived (likely because they dislike WayBack), but linked from [WayBack] Using PC power supplies in things other than PCs which I linked to in Convert/adapt an old ATX Power Supply into a Bench Power Supply with (or without) 3D Printed Parts

Note that [Archive.is] Data Collection And Live Upload refers to the – now gone – Inadequate and Deceptive Product Labeling : Comparison of 21 Power Supplies , which I found back as well:

In spite of the high end-user retail prices, our lab technicians were surprised by the test results. No fewer than 6 power supplies struggled under full load: 3 of the candidates simply went up in smoke, while the other 3 shut down prematurely. The “black sheep” among all the test participants was Maxtron, with the TOP-520P4. According to the manufacturer’s specifications, this power supply is represented to be capable of withstanding 520 watts – divided up over the corresponding voltage ranges. However, in our test, it ceased working at 446 watts. Completely dead!

Dean Bubley’s Disruptive Wireless: Debunking the Network QoS myth

Posted by jpluimers on 2019/08/09

QoS doesn’t work, except for one specific scenario:

Where QoS works is where one organisation controls both ends of a connection AND also tightly-defines and controls the applications:

  • A fixed-broadband provider can protect IP telephony & IPTV on home broadband between central office & the home gateway.An enterprise can build a private network & prioritise its most important application(s), plus maybe a connection to a public cloud or UCaaS service.
  • Mobile operators can tune a 4G network to prioritise VoLTE.
  • Telco core and transport networks can apply differential QoS to particular wholesale customers, or to their own various retail requirements (eg enterprise users’ data vs. low-end consumers, or cell-site timing signals and backhaul vs. user data).
  • Industrial process & control systems use a variety of special realtime connection protocols and networks. Vendors of “OT” (operational technology) tend to view IT/telecoms and TCP/IP as quaint. The IT/OT boundary is the real “edge”.

This is not news, but it’s worthwhile repeating: it is actually cheaper to build a network that can carry the traffic than building a network that keeps quality promises on a backbone that is undersized or close to capacity. Overprovisioning works, everything else does not, economically as well as technically.

Basically, all Harman Kardon amplifiers (including subwoofers) show power supply issues after a few years

Posted by jpluimers on 2019/07/26

Experienced first hand myself, all my Harman Kardon amplifier equipment (including subwoofer) have shown power supply issues after about 2 years of use.

Signs are devices not powering up any more, giving only a limited amount of power (for instance a subwoofer only blinking the power led), or intermittent shutdown failure (more often when it is warmer than 22 degrees Celsius).

There are companies making a living of just these power repairs (for instance Audiocare.nl who git all my defective equipment to work again for about EUR 100 per device: [WayBack] Harman Kardon – AudioCare.nl).

This is how you remove the power supplies:

The biggest issues are failing capacitors, and glue becoming conductive.

RP-SMA dummy loads for nonadjustable WiFi devices and Adjust Fritz!Box WiFi power – via Knowledge Base | AVM International

Posted by jpluimers on 2019/07/19

Via [WayBack] Knowledge Base | AVM International:

3 Setting the maximum transmitter power

  1. Click “Wireless” (“WLAN”) in the FRITZ!Box user interface.
  2. Click “Radio Channel” in the “Wireless” (“WLAN”) menu.
  3. If the option “Set radio channel settings automatically (recommended)” is enabled, proceed with the following section.
    • If the option “Adjust radio channel settings” is enabled:
      1. Click “Additional settings”.
      2. Select “100%” from the drop-down list “Maximum transmitter power”.
      3. Click “Apply” to save the settings.
For me, having minimal power was important since every now I needed to be able to connect to it, but only when I was in close proximity.

Hence the settings below: 6% Maximum transmit power is the lowest I could set.

For devices that cannot adjust their antenna output power which have RP-SMA connectors, I bought these to effectively throttle them:

Solid State vs. Electromechanical Relays | Arrow.com

Posted by jpluimers on 2019/06/27

For my reading list: [WayBack] Solid State vs. Electromechanical Relays | Arrow.com

When you need a power switching solution, you are faced with two competing technologies – electromechanical relays and solid state relays. So which is the right choice for your design?

Keywords: SSR versus EMR, SPDT
