  1. Trafo, Welcome to this forum. Is it a Solid State Relay you are looking for or just an IC? Ante ::)
  2. Bikerman, What would you need more than 60Volts for? :o Ante ::)
  3. Rhonn, I would not accept a leaky battery. The build-up of these acid crystals, which can lead to failure and even arcing and explosion, is not acceptable. If at the time of a high current pulse the clip is almost eaten through by the acid, the clip will burn off causing a spark. A battery under charge is constantly emitting hydrogen (NO SMOKING) that is explosive and disaster strikes 8). You can perform a capacity test on the battery to determine if it is within the specs. At least I think you should perform one near the end of the warranty time. I presume a 150Ah battery is quite expensive where you live, it
  4. Greg, So, you are in two topics with this one? Presuming the supply worked for a short time before the
  5. Bikerman, Well that would be nice to have both of them on the bench. ;D I can
  6. Darrin, Yes the low frequency enables the circuit to
  7. Rhonn, If Sweep means time / div (5.00mS) it
  8. Greg, It looks like U9 / U1 is a switching pre-regulator, the setup maintains the voltagedrop over Q9 to minimize the heat. Do this part work allright? C5 has an unusual symbol but I think you can replace it with a standard but low ESR cap, if it
  9. Greg, It seems like a strange way to reduce the voltage that much. There can
  10. Bikerman, I think it will work fine. So, have you decided which one to build then? Ante ::)
  11. Greg, The SG3524 chip is rated 8 to 40 Volts and you have 65VDC on the inputs. How is the voltage reduced and is the internal 5V ref used by the circuit? A schematic would be very helpful. Ante ::)
  12. Greg, Welcome to this forum. No schematic I guess? Have you checked the pcb, where this cap is connected to determine + and
  13. Darrin, I believe you are right, the PWM is the way to go. However it must be with a very low frequency to suit this application, something like 0.1
  14. Bikerman, Do you know if MJE4502 and MJ4502 are the same? I can
  15. Bikerman, If you decide to go for the dual supply here is some additional info: http://www.a-and-t-labs.com/K2_Lab_Power_Supply/index.htm You can buy a transformer for $75 if you like to have it all in one. Have you found any source for the LM317HV (TO3) or the MJ 15023? Ante ::)
  16. Shekhar, A touch screen is a completely different thing. The micro switch as we discussed it here is much too big and expensive for applications like that. Ante ::)
  17. Bikerman, I was in Denmark on Thursday so I had to get some Danish money, the exchange rate is 1.25sek for 1dkr. I purchased some Carlsbergs, nice to have a stock if the whether gets warmer (or even if it gets colder who cares) ;D. So, you are going to build this power supply then? Ante ::)
  18. Omelia, Welcome to this forum. It sounds like a strange device, can you explain a little more? God
  19. Bikerman, Dear neighbour, here you can buy the Mosfets in Denmark ;D. http://www.elfa.se/elfa/produkter/en/2458.htm They are not very expensive; they are cheaper than the 9540. I think you can get away with 8 of them if well cooled. 8) Ante ::)
  20. Vainajala, When paralleling lots of transistors on a common heatsink I usually don
  21. Quantum, No, sorry. :'( Did you get a peek before it was shut down? Ante ::)
  22. Quantum, A wild guess! I knew there is someone 14 years old. Close! Ante ::)
