TEC pulsed load causing voltage sags
Installed a new wiring circuit.. easy stuff, anyways I am plenty competent enough to build a simple little UPS like that. I mean there isn't anything that complex about building a rectifier and voltage regulator circuit and or step down transformers and I can easily buy a 1KW inverter. I don't...- OBCblackhawk

TEC pulsed load causing voltage sags
the lights are not turning off, they are just dimming a small ammount, but the pulses are so short and rapid it appears to make the lights flicker. It is very irritating and very noticable, my father has complained about it 3x now so effectively I have had to shut down several hundreds of...- OBCblackhawk

TEC pulsed load causing voltage sags
Just wanted to add I haven't cast out a UPS completely I just wanted to be assured it could suppress these sags. I am not into spending money on could helps... hell nobody mentioned there are different types of UPS's which would make a HUGE difference in this application... Really though, why so...- OBCblackhawk

TEC pulsed load causing voltage sags
LOL, this is a inherently uneducated response to overclocking... Look I have 3 of these chillers they ALL do the same thing even with every computer off in the room. A 3v sag in line voltage is plenty to cause a noticeable dimming of the lights. I fully understand the problem is complex, AC and...- OBCblackhawk

TEC pulsed load causing voltage sags
So the UPS I have is completely shot, and I am not about to go buy one to find out it will not work. Nobody has any ideas whatsoever on how to prevent this, I can't believe there isn't some solution. Bleh, this is why I hate AC if this was a DC load a simple old cap would completely fix this...- OBCblackhawk

TEC pulsed load causing voltage sags
It does not matter where you plug this chiller in, the problem is it that it requires fairly large pulses of current. Similar to when a large motor or compressor kicks on like your AC or fridge. This thing only draws about 300-500mA at 120VAC when not pulsing the TEC (peltiers) and draws 4-4.5A...- OBCblackhawk

TEC pulsed load causing voltage sags
As I had stated earlier I use it to cool my computer, and it does a excellent job of it. Instead of using normal old watercooling I can get sub ambient temps with this and it appears to handle fairly high heatloads fine. Cools two different highly overclocked CPU's and I know of a guy cooling...- OBCblackhawk

TEC pulsed load causing voltage sags
I can give it a try if I can acquire one to test tomorrow, I have a old one with a shot battery and a really low current rating.. stupid thing has a 2amp breaker, my computer alone trips it. Im open to more suggestions tho if you guys have them, I would really like to suppress these sags. But I...- OBCblackhawk

TEC pulsed load causing voltage sags
hello, I am no electrical engineer by any means but I've taken up a interest in electronics and whatnot. Now that we have my novice status out of the way here is my problem. I have a GE Medical TEC water chiller, uses peltier junctions to cool or heat the water. It works via a PWM circuit of...- OBCblackhawk
