...

The circuit is powered from the conveniently available +ve DC rail of the amplifier's PSU (range is circa +20v to +100Vdc).
...
Specifications:
- Requires > +24vdc power supply (can use +ve rail from your amp)

Looking for clarification given the conflicting detail offered in Post #1.

What's the minimum acceptable voltage that can drive the unit?

Is it +20VDC or +24VDC? I'd suggest that the conflicting data is resolved to avoid confusion / doubt.

I've got a built PSU that's delivering just under +/-21VDC under load.

Can I go ahead with confidence?

What's the minimum PSU voltage that the unit has been tested to?

 

[xrk971]

The version I tested used a Zener for the power, but the final version uses a hv regulator IC for maximum flexibility. Let me check with Jhofland.
Thanks,
X

 

[xrk971]

The internal regulator makes 15v for the circuit to do its job. It’s not a low dropout regulator so I would not go lower than +19v input for a supply to be on safe side. Hope that helps. I will update the 1st post to state this.
Thanks,
X

Apologies for my tardy response x but I've removed myself from the list due to a change in project direction. If I need some in the future maybe I'll be able to pick up some of these on your Etsy store?

 

[xrk971]

No problem - hopefully there will be spares left over when you are ready.

Hi Folks,
We are still waiting for the 1st verification unit to be built and sent to us for testing. Thanks for your patience. In the meantime, I am playing with a compact stereo headphone SSR relay DC protection and delay circuit that jhofland designed. It uses a +/- rail power supply and internal +/-5v regulators for operation. Uses dual 13mohm RDSon MOSFETs for a very compact pacakge due to extensive use of 0603 components and parts on the bottom side as well (opto-couplers). Still testing and debugging...

 

[menlobob]

What's the advantage of this over a mechanical relay design?
