      Arcade Power Supply - Which one should I go with?

      Hi all, currently looking for an arcade power supply.
      There are a few choices on ebay, leaning towards the Hei-Ma 15amp PSU from gamedudecomputers however even though its listed at 240volts, the unit itself has 220volts written on the stickers.
      I want to comfortably run my pcbs and unsure on if this would be ideal, does anyone have any suggestions or possible experience with this unit?

      Cheers

      Australia is not 240V - it is 230V

      Anywhere between 220 and 260 is perfectly OK.

      Sorry to veer a little off topic, but this seems interesting: http://www.ewh.ieee.org/r10/nsw/subp...e-Voltages.pdf

      From Ausgrids 2017 Network Standard

      6.1 Steady state supply voltage
      6.1.1 Range of supply voltage
      Supply voltage is the voltage, from phase to neutral or phase to phase, for electricity that is
      supplied at a connection point. Maintaining this steady state supply voltage is important to ensure
      appropriately designed equipment does not malfunction and is not damaged.
      When Ausgrid identifies or is notified that the steady state supply voltage is outside the specified
      target range, Ausgrid will take reasonable steps to modify the network to ensure that the voltage
      will be maintained at the required level and achieve Ausgrid’s steady state voltage supply objective.
      6.1.1.1 Low voltage supply
      Ausgrid’s objective for the operation of its network is to maintain a target steady state phase to
      neutral supply voltage (measured as a ten-minute average in accordance with AS 61000.3.100
      Limits – Steady State voltage limits in public electricity systems) within the range of 216V to 253V
      at connection points under normal operating conditions. This range is the nominal voltage range of
      230V in Australian Standard AS 60038 Standard Voltages, with a tolerance of +10%/- 6% to allow
      for voltage regulation within the network.
      It should be noted that due to system operational constraints and physical network limitations, it
      may not be possible to maintain the target steady state supply voltage range for all of the time at a
      given connection point.
      Where the above target steady state supply voltage range cannot be maintained, particularly under
      abnormal network arrangements such as may occur during maintenance, Ausgrid’s objective is to
      maintain a steady state voltage within the range 207V to 262V at all times. This range excludes
      situations arising from faults or voltage interruptions.
      Following an Energy Networks Association review in 2011, Ausgrid commenced migration from a
      nominal voltage of 240V to 230V. Over time, the normal average Ausgrid network voltage will be
      reduced from around 250V to around 240V.


      Take your pick

      Heh, according to my link Standards Australia decided to transition from 240V to 230V over 20 years in 1983... AusGrid decided in 2011 to commence migration. Yep, standards take time!

      guess I'll be fine with the 220 volt one? just wanted to double check before i pulled the trigger on the purchase

      cheers

      Yup, most people still think Australia is 240V but the reality is it was changed a long time ago. I guess many refer to the voltage "generically" as 240V for historical reasons

      Yep that will do, just make sure the switch underneath if it has one is switched to 220 not 110.

      I've brought Hei-Ma's from Gamedude and never had a problem with them running my original game boards.

      thanks for the feedback, will go on an order one.
      just one more thing i forgot to mention, i'll be running a video converter board as well that requires 5volts and ground
      can i just screw the 5 volts wire from the converter along with the 5v wire from the jamma harness?

      cheers
