Group Buy: SST03 Soft start for toroidal transformers - Page 2

fredlock · 30th March 2011, 04:56 AM

Hi Peranders,

On your website, it says;

" Other mains voltages
The pcb is not tested yet for 110-120 VAC but I'll expect that 2 x 0.68 uF (C1, C2) would be sufficient. The capacitor value is also dependent of the relays and their current consumption."

Did you get any feedback from USA DIY'ers, that ordered your soft start kit, if they encountered any problem using it on their amps?

peranders · 30th March 2011, 07:14 AM

I may change the text because it is tested and noone has come back in this matter.

peranders · 21st May 2011, 08:10 AM

I'll go ahead with this group buy. I think there is enough in preorder. Please check over your orders and I'll send you a Paypal invoice.

peranders · 22nd May 2011, 07:19 AM

I have sent a message to you all (except for Murdoc) about checking your orders and also come back to me when you have done so.

No. Didn't think about that but feel free to mention this.

Hi guys,

Before you go ahead with your design and purchase. Take a look at this. It is pre-built and I think cheaper. I am not sure if it is complete but it looks like it and much cheaper - at least in the US.

Amperite - 120A1-100MST1A - Time Delay Relays (TDR) - Sensors, Switches & Relays - Allied Electronics

Amperite - Solving your relay requirements since 1922

These are relays with a delayed turn on accepting up to 240 v to turn it on. The standard product is 2 Amps and up to 10 Amps are available from the factory.

Timing is from 0.1 sec to 10 secs.

Would be interested if anyone has tried this.

Notice that this product is for DC, not AC.

ua100k · 27th May 2011, 05:17 PM

Yes, This particular model it.
If you look at the manufacturers web site, they will show you how to order to your specs - ac/dc, voltage, Current, time - variable or fixed, etc.

I will try one and let you know.

I would appreciate if you start a separate thread about your findings. Notice that my solutions has additional features like a mains switch and also terminals. If you use a time relay you must also have the resistor and some additional terminals and maybe also a relay socket. In my subwoofer I used an Elesta relay with a very small delay unit inserted in the relay socket.

Very good stuff, not cheap either.

Thanks for the relay tip. I will start a new thread. Sorry for the intrusion.
