FS: Speaker protector using solid state relay

[nigelwright7557]

I have a full speaker protect pcb with no transformer for use where there is no 230VAC mains. Just add your own local 0-9 0-9 VAC 5VA transformer and you are good to go.
£14-99 plus p+p £3-99 UK and £12-00 rest of world.

 

[nigelwright7557]

I am happy to supply bare pcb's if anyone is interested.
I will include microcontroller already programmed.
£4-99 plus £3-95 p+ if uk else £11-99 p+p rest of world.

£5-99 for DC protect, over current detect and power up/down detect pcb.
plus £3-95 p+ if uk else £11-99 p+p rest of world.

 

[nigelwright7557]

Three generations of speaker protect circuit.
1st is mechanical relay with dc detect.
2nd is solid state relay with dc detect.
3rd is solid state relay with dc detect, over current detect and power up/down detect.

An externally hosted image should be here but it was not working when we last tested it.

 

[nigelwright7557]

Built up a couple of the all singing all dancing speaker/amplifier protect modules.
I have left out the mains transformers so if you use a different mains to the UK you can add your own local mains transformer.
£14-99 plus postage costs.

I can add mains UK transformers for £4-99 extra per pcb.

Still for sale ?

If this is still available with transformer please send details so I can arrange payment
Thanks ian

I still have some pcb's left.
Simple DC protect and power up delay with and without uk mains transformers.
A couple of all singing all dancing pcb's without transformers, they are dc protect, over current detect and power up/down protect.
£9-99 small pcb without transformer.
£12-99 small pcb with uk mains transformer.
£14-99 for all singing all dancing model without mains transformer.
Shipping is £3-99 to uk or £11-99 to rest of world.

An externally hosted image should be here but it was not working when we last tested it.

 

[nigelwright7557]

Still got a few speaker protect pcb's left.
Simple one or full monty protector.
Down to the last few now.
PM me if interested.

 

[nigelwright7557]

Still got a few DC protect with UK mains transformers (230VAC.)
£12-99 + p+p (£3-99 uk and £11-99 rest of world.)

 

[nigelwright7557]

Only one full monty protector left.
£14-99 + p+p (£3-99 uk or £11-99 rest of world)
Of £19-99 with uk mains transformer fitted.

Pm'ed you.

 

[nigelwright7557]

Pm'ed you.

And pme'ed you too.

 

[nigelwright7557]

All the comprehensive large protect pcb's are gone now.

I have a few left of simpler DC detect and power up delay models left.
£7-99 for pcb's without uk mains transformer.
£11-99 for pcb's with uk mains transformer fitted.
£3-99 p+p uk and £10-99 p+p rest of world.

 

[nigelwright7557]

Note these pcb's have solid state relays so no problems with relays wearing out.
