I have a variable voltage linear DC power supply that can provide up to 18v @ 2 amps; the load that is being powered only requires 5-9 volts and about .5 amps to run properly. The machines that are being powered through the power supply are the only instruments used that are sensitive enough to show an affect of this drop (lights in the room don't dim or flicker, other devices on the mains circuit seem to be running perfectly)
The voltage and amperage readouts remain stable (+/- .1 volts), yet the load eventually bogs down and wont get the force needed to run properly or at all even.
I have powered several devices, with 2 separate power supplies, and running the power supplies off 2 completely different mains to help determine the cause, experiencing the same loss of power to the device. The odd thing that i cant figure and am quite confused by, is the inconsistency of the said problem... One day everything will run great through the power supply, other days the power will start to drop after 20-30 minutes of load, and other days the loss isn't noticeable for a few hours of operation.
I have replaced the devices, bought a new power supply, new power cords, pretty much new EVERYTHING running from the load to the wall outlet. A few things that i have considered the possible culprit, but haven't had a chance to troubleshoot would be dirty power, input and output frequency, supplied power to the mains, other loads on separate circuits, and faulty wiring of the mains (which i wouldn't be doing myself).
Any ideas to what exactly is even dropping (if the volts and amps are remaining consistent), and/or what could cause such a drop, would be much appreciated!
Thank you and feel free to ask any other questions
