Solartron AS1410 power supplies
I have been asked for information about the AS1414 power supply, one of the AS1410 family.
When introduced in 1964, they were well ahead of other designs as they used a pulsed SCR to switch the input feed so that the series pass transistor only had about 5 volts to drop at the chosen output voltage and the power dissipated was kept down. I find it very convenient to use, with the current meter full scale being effectively at the current limit setting and the digital voltage setting. I attach a specification sheet covering all models as it may be of general interest. I have the full manual and PCBoard layouts. wme_bill |

Re: Solartron AS1410 power supplies
sounds like a clever idea,be nice to see the schematic to see how they did it.

Re: Solartron AS1410 power supplies
Yes, they are a good supply and well ahead of their time as you say. Mine is still going strong (attached) though I tend to use a modern triple supply most of the time these days. I'm not sure how old it is but I've had it at least 26 years and the company I worked for must have had it even longer - probably from new. I acquired it when they were skipping old kit prior to a move.
I've attached a rough pdf, which is similar to the previous upload but includes a couple of circuit diagrams if anyone is interested. Jerry |
