Check out this WEB sites for the full specs. http://www.fixya.com/answer/answerpageslideview.aspx?ctg=8&p=2&thid=17837778
Triac or SCR? Either way for the discrete 3 terminal device, go with a 1000 volt 8 Amp device. A Triac can replace an SCR in some circuits. Depending on triggering source, sometimes a "Sensitive gate" type is needed for trigger pulsea that are only about 2microAmp.
If you have the specific specs for the discrete device, you can scroll through the products available at Digikey http://www.digikey.com and enter Triac or SCR into the search criteria, and then you can narrow the choices down by the filters.
hi, You have to check the Driver circuit board for the motor. There is motor control IGBT Insulated Gate Bipolar Transistor) in this board .If the IGBT is short then the treadmill will try to run at high speed without setting any value or witout pressing the start button. You have to check the OHMS between the seocnd and third of lead of the IGBT. If it shows less than 100 Ohms then the IGBT is short and you have to replace the same. Also you have to check the connection to the control pannel. Is there is any loose conatct. Remove the connection in the motor control board which go to the control pannel and reconnect it. Also check the speed sensor. In most of the treadmill you can find the speed sensor near the motor pully. Remove the speed sensor and clean it and the refix it. Remember one thing remove the power of the treadmill and leave it for 30 minutes then only oppen the treadmill. Because there is high voltage storage capacitors in the motor control board which will hold charge for some time even after the power is disconnected. i ahve added the picture of IGBT for your refference ok
I have a PX-42VM5A and my Power supply is a PNT-426 (by Sanken Electric Co. LDT). Here are my specs: INPUT: AC 100-240V; OUTPUT: (there are nine outputs) +170v 1.6A; +60v 1.6A; +5v 4.0A; +2.5v 1.9A; +3.5v 1.9A; +7v 1.0A; +12v 0.5A; +12 v 1.9A and +6v 1.2A
This is a fairly ordinary 200 Amp, 600 Volt IGBT. It might cost this much because they just aren't made anymore.
Unless you wanted this part for a specific reason that you didn't mention then I think you'd be better off buying some more modern 'bricks' with better performance.
I got five 600amp 1200volt IGBT's for $100 off ebay a few months ago.
An avenue of research that might be of interest to you would be SSTC or solid state telsa coils. Google searches will find you many SSTC sites with IGBT H bridge circuits and drivers basically doing the same thing as you are intending.
