Its certainly taken a beating, chances are its far worse internally. Many eBay used eloads are harder to spot, it looks good on the outside but its taken a beating on the inside. If the driver MOSFETs or transistors were run in a hot ambient lab the lifespan of those power devices will be much worse than one kept cooler; likewise those used Prodigit units are from Israel? so its naturally a hot climate too; even as parts one thing to worry about is unobtanium, so even if cheap rebuilding a $3k eload on eBay may not be possible. That's one advantage of the Array tear down, except for the firmware, all the parts are generic, particularly the ones that will likely wear: power MOSFETs, sense resistors. --- Quote from: peter.mitchell on November 06, 2012, 02:13:31 am ---I just saw this; http://www.ebay.com.au/itm/150792412128 and thought immediately "well, someone must have held a grudge against those loads" --- End quote --- |

Just picked up a used Tekpower branded 3710A. So far so good, though menus and beeps are a bit annoying. So is the lack of pulsed load mode, but I knew that going in. Will be taking it apart soon to check out the build quality on this one. Does anybody have a part number for the RS232-USB adapter ? |

Pretty sure it's the same as the Array ones. |

Part numbers vary by who relabels the model, but the CSI ones are here: http://www.circuitspecialists.com/dc-electronic-load-csi3710a.html --- Quote from: reagle on January 26, 2013, 06:01:54 pm ---Just picked up a used Tekpower branded 3710A.

Looks like P/N 3312 for the USB version is universal across the brands. On a related topic, in Saturation's teardown pictures rack handles are shown as part of the accessories, separate form the unit. How are they mounted to the case? I am trying to get them removed, and it does not appear possible without taking the unit apart :( |
