    I believe electronics sold in Japan are required to only support their 100 volts AC mains power, and to not officially support other voltages, to discourage them from being exported and sold overseas. Of course this is often just a formality, and many JDM items either can easily be modified to operate on different voltages, or are actually multi-voltage capable, but don't advertise it.

    I have imported quite a lot of electronic equipment from Japan to here in NZ where our mains is 230 volts.
    'JDM' (Japanese Domestic Market) equipment always states on the plate that it is 100 volts, even on the units that are capable of running at higher voltages.
    I suspect they do this because the JDM stuff was never designated to be sold or used anywhere but Japan, so there's no need to advertise the fact it will work at any voltage other than 100 volts.
    Probably 2/3 of the gear I have imported was strictly 100 volts only, and I have had to convert those to 230 volts by changing out the internal mains transformer.
    On some units I have got lucky and the internal transformer has multiple primary windings so is easy to change to 230 V.
    As for the SONY Digi-BETA, I have worked with a few of them over the years, but all of them have been PAL units and had the 100 - 240 volt plates on the rear.

    Sony Betacam DNW-A45 sometimes had the same issue. The Sony DVW-A500 (NTSC) was well know for accepting power requirements of AC 90V to 265V (48Hz to 64Hz) even if the input was only 100V (AC) due to the higher serial numbers back then (Anything Higher than serial code 11944). The power consumption was 300VA (240W). Sony may have made a error by not mentioning the 240V (AC) acceptance next to the 100V (AC) input on the manufactured label. The unit should be fine to run on 240V (AC).

    18:00 Actually the acceptable "normal" voltage for Europe is 230V -6%/+10% (216V to 253V) So up to 253V is considered normal and every power supply should tolerate that. 253V in still considered in spec.

    Part of the 100V marking on non PAL machines was probably part of the marketing/sales separation of PAL and NTSC markets to maintain price differences.
    In addtion there were 3rd party kits to convert 480i DVV-A500 machines to 576i with some component changes and there may have also been full switchable mods. I vaguely remmember Sony cracking down on buying the Sony spares for the 3rd party conversion kits.

    My mains voltage often hits 250V here (yes, I'm sad enough to log it and graph it!) typically overnight in the early hours of the morning. One of our labs in work hovers around 252V nearly all the time, and it causes problems with UPS units cutting in with their factory default thresholds because they sense an excessive input voltage.

    I found something similar with panasonic DVD recorder from the EZ series that I imported from the UK to the USA - Was marked 220V only while US models are marked 110V only. I thought I'd have to use a step up transformer with it, but turns out it worked on the lower voltage just fine. I did compare power supplies between similar models and US ones have a larger main higher capacitance and a slightly lower voltage rating (350V/100uf in USA vs 400V/47uf on the UK model), presumably because they have to "switch" twice as often to get the same outputs when using the lower voltage . I basically just increased the capacitance of that main cap and I'm pretty sure it is otherwise similar now other than possibly should have higher amperage mosfets. Apparently the control circuit that handles the switching doesn't mind the higher input voltage and that's probably why yours hasn't blown up. But agree, universal supplies would have been nice and probably would have added something like $1 in cost to have both voltages fully supported. A lot of the internal transformers also will have a midpoint tap that you can use so that you can use two different input AC voltages to get the same output voltages. I didn't mess with that on my supply since it worked, but could be something to consider if you run across something else that will not work on 220V.

    • @Ragnar8504
      @Ragnar8504 7 หลายเดือนก่อน

      Of course there's also the possibility of running 240 V dedicated circuits in the US, every house has a split-phase 120/240 supply and US 240 +/- 5% is well within the limits of European 230 +/- 10%. Admittedly it's a bit of a faff but could come in handy sometimes. The most common choice of plugs would be the NEMA 6-15 but I don't think there's any legal requirement to use them, you could use UK or EU sockets and plugs.

    Most switched mode power supplies are universal even if they don't say that on the back, as an experiment, I have a 220V/110V stepdown transformer ant every 230V TV here in the house runs happily at 110V including CRTs, even though the back only says 230V.
    The first CRT I tried with a transformer was a 29" Samsung TV, it said 230V on the back but on the manual it said the power supply worked between 90 and 260V, and sure enough it worked fine at 110V though it was weird to hear the degausing coil taking longer to switch off.

I am in a number of motorhome and caravan forums and I regularly see people saying that their caravan etc is set up for 240 volts. It baffles me. We have NEVER had 240 volts here, it has been 230 ever since mains reticulation was provided early last century. Where are people getting 240 from?

      @@Matt_Quinn-Personal_Account If the supply frequently exceeds 230 V +10% I'd complain. Anything up to 253 V is acceptable but more isn't. I'm not sure about the UK but most of Europe eventually settled on 230 +/-10, with an transitional phase of 230 -10/+6 to make sure old 220 V equipment wouldn't be damaged. The assumption seems to have been that by the time the tolerance band was widened to +10% all older equipment would have been discarded.
      Mains voltage is usually higher in rural areas than in city centres to compensate for voltage drop under load. Long lines, particularly 230 V ones (as opposed to 10 kV+) have considerable voltage drop under load, so to make sure the actual voltage remains within the limits under full load, the suppliers crank the idle voltage up as far as they can. In densely populated areas transformers are larger and cable runs usually much shorter, so the actual line voltage tends to be much more stable throughout the day.

    I feel sure that if the power supply was 100V only it would not run for very long on 240V before something let go! Perhaps the supply was indeed swapped for a PAL one. Often someone would put a warning label on the machine if it was 100V only.

The DC output will be the same for both cases, and the mains frequency is not used for the electronics, or are there any AC motors used in these pro machines ?

  • @JacGoudsmit
    @JacGoudsmit 7 หลายเดือนก่อน

    The parts and documentation that you're showing in the video would not have been enough to convince me that the power supply is officially 240V capable. I know that lots of times, manufacturers use the same parts in different power supplies. Here in the USA it's quite common to see 250V fuses and 450V filter caps in power supplies that are intended for 120V. I would have taken the power supply out of your PAL recorder and compared more parts to convince myself that it would be safe to use it on 240V.
    That being said, I also know that many switching power supplies are very capable of being used well outside their specifications. The VCR I brought with me from the Netherlands works just fine on 120V even though it says it needs 220-240V on the back side. But putting 120V into a 230V power supply is a bit more safe than putting 240V into a 100V power supply I would say, so I'd be a bit more cautious.
    Oh well... I guess if it blows up you always have a spare from your PAL machine... 🙂

    • @video99couk
      @video99couk  7 หลายเดือนก่อน +2

      What convinced me in the end was the part number of the power supply is identical to that being sold for a PAL machine. So I knew then that the power supply was OK for this voltage. The only question was the input board, and all the components are 240V+ rated on that.

  • @stphinkle
    @stphinkle 7 หลายเดือนก่อน

    The other way you can test for suitability is to see if the output voltages are what they are supposed to be.

    • @hugoromeyn4582
      @hugoromeyn4582 7 หลายเดือนก่อน +1

      The only component you can test that way is an unloaded 50/60 Hz transformer, not a complete power supply because they have rectifiers, voltage regulators, transistors and other voltage rated components like capacitors, which can suffer a lot of damage from overvoltage as well.
      For example... In a 110V>12V power supply, the transformer will output 12V AC. After that, it's rectified to DC and the voltage will increase to 16.9V.
      Most of the time, a voltage regulator IC is used to bring the DC voltage back to 12V, just regulating the voltage 4.9V down. Perfectly fine.
      Now, you connect the same power supply to 240V mains. The transformer is now outputting 26.2V AC and after it's rectified, the voltage increase to 36.9 V.
      The voltage regulator will regulate it also to 12V, but now it's regulating 24.9V down and it's getting overheated within minutes and dies.
      When you do a quick test, you'll measure 12V at the output, assuming it's all fine. And that's just one example what possibly can go wrong with a simple and straight forward power supply.
      In this video it's a switched mode power supply, that's even worse with more components that can suffer damage. Luckily, Sony engineers where ahead of their time designing multi voltage power supplies before it became commonplace.
