Anyone have a loose str3123 or str3130 they could test?

I'm just looking for some comparison readings..if you use the diode setting on your dmm and test each leg (take 30 seconds) and post the results that would be awesome!

eg 1 to 2, 1 to 3, 1 to 4, 2 to 1 etc...

I have a k7000 19" with a str3123 that works but the voltages are out and I don't have a spare 3123 to compare it to...

Thanks!

STR3125 - not exactly what you are looking for, but the STR3110 3113 3115 3120 3123 3125 3127 3130 are all the same, just different output voltages (110/113/115/120/123/125/127/130 volts respectively) not sure exactly what the 5th pin is for, it's usually cut off...but the one i have here still has it's leg. so i've included it in the measurements. the first is the diode measurement, the second figure is the resistance. resistance measurements may vary from voltage to voltage since the feedback resistor would be a slightly different value. basically if it's not way out to lunch (shorted or open), it should be good enough.

(-) on pin 1 (+) on pin...

2 - 0.627 - 280.2K
3 - OL - 317k
4 - 0.531 - 269.7k
5 - OL - 314.5k

(-) on pin 2 (+) on pin...

1 - OL - OL
3 - OL - 78.3k
4 - OL - 31.39k
5 - OL - 75.9k

(-) on pin 3 (+) on pin...

1 - OL - OL
2 - OL -78.4k
4 - OL - 47.23k
5 - 2.226 - 2.446k

(-) on pin 4 (+) on pin...

1 - OL - OL
2 - 0.958 - 30.71k
3 - OL - 45.61k
5 - OL - 2.446k

(-) on pin 5 (+) on pin...

1 - OL - OL
2 - OL - 75.9k
3 - 2.197 - 2.446k
4 - OL - 44.78k

hope this helps

Many thanks!

I recently discovered that the str30123 is the same as the str30130 which can be converted to a 3123 or 3130 with pins 1 and 3 reversed..
