content: I bought an IT8511 programmable DC electronic load off of ebay for half your suggested budget and I LOVE IT! The company is officially Itech, but it's really made by BK Precision (they freely admit to it). It is built like a brick shithouse and it seems to be rich in features (even the computer software works well). The displayed voltage/current/power readings are all displayed to 3 decimal places and are very accurate (compared to my Fluke 87-V and DM3058).The only thing that may put you off on this unit is that it is rated for 150 watts / 120 volts. They do make units which can handle the 300 - 600 watts that you specified but it will probably cost you a lot more.

content: Nope, this isn't just rebadged, BK Precision actually owns the company Itech. They use the brand Itech outside of North America where their customers can't or won't pay as much as Americans will... but it's the EXACT SAME product (look at the 8500-series DC loads by BK, they're the exact same machine)

content: Quote from: olsenn on February 02, 2012, 08:01:01 pm?? B&K Precision lists on software with the 8500 or 8502. It seems they have a LabView driver and that it can be programmed with Python. Can you elaborate?Thanks

content: Quote from: olsenn on February 02, 2012, 08:15:30 pmahh did not know they are that related.... :-) thanks for correcting me.But it still might be ITECH that builds it and ships it with both BK & ITECH label. BK just charge more due to the "brand" :-) Might still have been designed in the US - but hard to know.

content: QuoteThe software that is provided with the IT8511 is the BK Precision software that runs all the 8500-series DC electronic loads. I'm not sure about the programmable through Python bit as I don't use Python, but it does have a LabView driver available for it. The only downside as far as connectivity is conceared is that none of the 8500-series units have USB... just a TTL serial port. I don't notice any problems with update rates, but you will need to purchase a TTL-to-RS232 or TTL-to-USB adapter (available for $50 on Mouser.com) to connect it to a computer.
