content: looking for an electronic loadbudget ~400euro for 300W / ~1500 euro for 1200W>=300W>=200V>=10AI'm currently considering to either get a M9712B or ET5411 from aliexpress, but would rather get a nice second hand unit as long as it's a good deal.

content: What is the ET4511? Couldn't find it on AliExpress...I have a maynuo load, but only 150W IIRC. I have to say I was quite disappointed with the load regulation, as well as the fact that you can set load values that it doesn't have the regulation to set (they display more digits than can be set). Overall I wished I'd bought a agilent mainframe with load modules second hand from eBay or somewhere.

content: Are you sure about the HP model being a 8812b? All the HP loads I know of start with a 6.The newer agilent Mainframes are supported in BenchVue but the older 6500 series aren’t.I’ve got a 6500 fully loaded and it is very nice to use. The transient test is really useful for testing power supplies.

content: Quote from: Ordinaryman1971 on January 20, 2020, 11:59:21 pmnope, from what i can find that model has a 120V voltage range, I need 200Vmeanwhile, the DLP-400-20-2000A arrived, If everything works well this will do the job! Ended up paying 445euro including shipping, for a 400V, 20A, 2kW load.I feel like this is pretty reasonablelet's hope everything works, the user interface is pretty old fasioned
