Re: unknown electrical connector
Compatible connectors are made by several companies, one of them is Phoenix contact. <http://cdn.sigma.octopart.com/5351697/image/Phoenix-Contact-1754465.jpeg> ST

unknown electrical connector
I'm trying to determine the best way to hook up to the connector shown in the Photos section under Miscellaneous/unknown.connector.jpg. It is a stepper motor driver board. I have searched the internet

Re: LCD monitor power supply
Yeah This is a new concept for me. Caution in using a working voltage that is less than what is required, but a working voltage that is greater than what is required? Roland F. Harriston ** Ross

I think it is nonsense and would like to see that reference too. ST

Re: Motor drawing more current
You mean the 24.5A vs. the 22 rated amperage? Or are you talking about the one that failed (drawing 80A when it did so)? Thanks, Dave

Re: LCD monitor power supply
Steve, Do you have a reference for that? I have never heard that before and would like to understand the science behind it. Thanks, Ross

Re: LCD monitor power supply
Do NOT give in to the temptation to get caps with much higher voltages. Electrolytics must run at something not to far under their rated voltage. I'm not sure what the voltage derating is supposed to

I am in my first year of BMET classes and was wondering if anybody had any study guides or old quizes from the electronics devices 8th edition by Floyd. Thanks

Re: question
Gold bars? Not that I've seen. However, I do some metal detecting. I've found an 1888 Canadian dime, an 1896 nickel, a civil war button and other interesting items. One day, in my back yard, I found a

Oscilloscopes cheap used Re: question
For those just starting out, it is wiser to buy a few staples in good working order. DMM, oscilloscope, signal generator. Then at least you can use those to test and troubleshoot. Steve Greenfield

Motor drawing more current
The motor is a split-phase (2-wire) 230VAC, 5 h.p. asynchronous cap-start motor on a commercial compressor driving a 2-stage air pump via V-belt drive. This motor (#3 in the life of this compressor)

That was in Concord, NH. At other times, I've gotten a stereo zoom microscope for $25, a 110MHz RF generator for $1, and other amazing bargains. Also got a lot of junk that couldn't be repaired. The

Re: LCD monitor power supply
Mark T.: Also, consider getting caps with a higher temperature rating. Nichicon makes good caps that have higher temp. ratings for not much more than the cost of lower temp rating devices. Roland F.

Re: LCD monitor power supply
I attached a very quiet "muffin" fan to the back of a 27 inch flat screen CRT TV that we still use. Being aware of heat vs capacitor life, I have found that the fan makes a big difference. I wonder
