![]() I have not tried the loads on Ebay but use different electronic loads extensively every day. To: Re: Any experience with ELECTRONIC LOADS would be appreciated Ditto things like HP system PSUs and so on. ![]() It's worst point is that it dates from HP's non-backlit-LCD era so the display is a bit poor but I tend to use it under GPIB control rather than via the front panel anyway becauseĪ) It's mounted at the bottom of a rack and as one gets older the ground gets further away of course, so it takes longer to get down and press the buttonsī) Some of the functions can only really be accessed through that interface andĬ) Having produced a couple of little scripts it's actually quicker to set things up that way. I got everything for less than half the 'typical' price. I'm happy with it and have had no issues, like much of what's on ebay if you can wait a bit, usually you can get things at a good price. Used it a fair bit for PSU testing including response to fast transient current loads and for developing inrush limiting circuitry to put ahead of DC-DC converters in 28VDC avionic applications. I got an HP6050A from ebay a couple of years back and have 60501B (150W 60V), 60502B(300W 60V) and 60503B (250W 240V) modules to go with it. I can add a fan to keep the heatsink cool if This should be no problem asģ) Power of about 50W. Has anyone bought an electronic load off of Ebay? If so what hasġ) Voltage as high as possible: it looks like that will be about 100VĢ) Modest current drain of an amp or two. It would appear the Ebay ones are variations on about 10 differentĭesigns. I occasionally have a need for an electronic load. For certain tests a true resistive load is the only Whatever you buy or build, always keep in mind that there is a control On a heatsink, with a shunt resistor in the source lead.Ī simple opamp control loop can do constant voltage/current/resistance control. You can make a load fairly easily, I have always used a beefy mosfet There is information about them here, they are apparently no so bad: I have also built several of my own where commercial products did notĪre you looking at the Chinese loads in a desktop case such as the I have not tried the loads on Ebay but use different electronic loads ![]()
