Okay, so I have in my possesion an NTE Electronics, INC, 4-32VDC 480 VAC 75 AMP solid state realy. We use these things in the theater I work in as part of the House Light Dimmer. It has a number: RS3-ID75-41, I guess that is eihter a model number or serial number. The ones currently in the rack are 2-26 volts, and I think those are the ones i'm looking for. Wither way, does anyone happen to know where I can get more of both voltage. I will ask My tacher(it's a perfroming arts center built onto the high school, my teacher is also my boss......) which one we need. All I know is that we hae both voltages in there, and one of them causes the lights to "shake" at low levels. I wanna get rid of that, so I gotta replace the relays. Thanks

Here is what I was able to locate in Google, in as much as a search for suppliers... That part number, BTW is RS3-1D75-41, and there is really nothing to locate on the web, unfortunately. They run about 65 to 75 dollars each - OUCH...

This is a link to a picture on the NTE website... and this is a link to the manufacturers web page with specs for that relay.

Hope this helps! Let me know if you need more info, and I'll do what I can!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

So what else other than the racks, can I use these things in? I guess the easiest question would be to ask, what do they do?

They do the same thing as a Bosch relay, just no moving parts. The input (control) voltage, in this case - 4 to 32 volts DC, turns on an internal device called an SCR (silicon controlled rectifier) allowing current to flow ONE way, in this case - 36VAC minimum to 530VAC maximum - at UP TO 75Amps. These particular SSRs have two SCRs in them, back to back, allowing two way current flow. For the full 75A current capability, they REQUIRE a proper heatsink - use what is recommended by NTE. They are really only good for DC control of an AC circuit, they are an on-and-off device - i.e. no fading, and they CAN be (electrically) noisy, unless proper design steps are taken in the manufacture of the device.
