Regenerator voltages question?

Postby Starwarsmike2422 » Sun Nov 04, 2018 11:17 am

Hi this might be a silly question.....

I have a PS Audio P5 regenerator, I’m in the Uk. So I set the voltage to 230 volts. From my limited knowledge I understand equipment can run at +10% to -6%, I also believe the uk standard was 240v but now declared as 230v due to tolerances. So my question is, what would be the best voltage to set? 230v, 235v, 240v? Or does it not matter? As it’s all about stable supply?

My incoming voltage is 235v +or-0.5%. Seems very stable coming in. My THD in is 0.2%.

My output voltage is 230v +or-0.1%. My THD out is 0.1%.

Note I am only using the Regenerator for my DAC & Streamer. My amp is too big for the P5. I was very pleased & surprised by how much this had increased the SQ.

My understanding is that although it doesn't really matter, the manufacturers stick to the 230v standard, so I imagine that's the best to use on your regenerator.
Look on the back of a DACXP and it will say '230v'.

My AG1500 regen is permanently fixed to 230 volts.
