60-70v unregulated power supply recommendations

[john swift]

Hi John

the link to the transformer does not work
a web search for the part number cm0625224 links to

https://airlinktransformers.com/prod...ange-cm0625224

power supply circuit



I notice that data sheet for the transformer does not specify the transformer regulation (change in output from no load to full load)

the 24V output from each secondry is when fully loaded
I expect off load it could be 5 or 6% higher

in my part of the UK, depending on the time of day
the mains supply is 243 to 248 V RMS

when the mains supply is 248V
the DC power supply output can be about 77V DC off load
or 73V DC fully loaded

John

PS
with my mains supply of up to 248V
If I decided to build a power supply
I may opt for CM0625222 with two 22V outputs wired for 44V
to give me 71V DC off load
