content: Does anyone here have experiece with equipment from EA ELEKTRO-AUTOMATIK? I may need quite a few power supplies and dummy loads which need to run 24/7 but I would like to know for sure I'm not buying boat load of lemons.

content: A couple of years ago a had power supplies from them in daily use at a former employer.If i remember correctly one was a dual 30V/5A type.It was really good quality and i liked them. Very robust design, mechanically and electrically.Don't know if the quality has dropped in the meantime, but i don't think so.They got a little bit out of my focus, unfortunately. What models are you interested in?I think i should also spend a closer look again.Regards,Martin

content: I had to deal with EA in a previous job quite a lot.We didn't actually use the gear ourselves, we only sold it on to some big companies and government departments. But in the 14 years I've been in that job I can only remember one problem we couldn't solve and that was about some big arse switching PSU's we sourced from EA, please note that the PSU's in question were MeanWell branded and the customer treated them very badly.I wouldn't hesitate sourcing stuff from them at all.

content: Hi!I'm using a 2400W electronic load from EA and I'm pretty satisfied. Build quality is solid like a rock (and heavy!) and service/support is at the top. Consider buying the "HP" (high power) versions of the loads - they are only slightly more expensive, but have a larger heatsink und run cooler/longer (specified at full power and 40°C ambient).Concerning power supplies, I would also consider TTI - IMHO build quality is equal but the value for money is even better.Michael

content: Regarding the power supplies I'm thinking about using some modules from Meanwell. I need a fixed voltage anyway so a lab grade PSU is overkill. The hint about the load is a good one. In my setup I may need to get rid of about 2kW on average over 24 hours.

content: As long as your peak dissipation power does not exceed 2400 watts, then the EL 9000 HP 2400W series should be fine for you. If you need higher peak power, EA also delivers 4800W and 7200W units. :-) Don't forget the GPIB or ethernet/USB interface card.Also consider not putting them next to your desk - at full power the units are getting "noticeably loud", almost annoying - but that will be the same for all air-cooled units in this power league.Michael

content: This is for a setup in a factory environment. Then again noise could be an issue. EA also has units which can use the mains as a sink but they are 3 times as expensive. Even at the load levels the projects needs it will take several years to make up for the difference.

content: Quote from: nctnico on February 12, 2014, 05:10:37 pmKeep in mind that you need to check back with your electricity provider about connection and an additional separation module which allows them to disconnect the unit in case of maintenance.The watercooled option is definitely nice, but narrows the use of the unit apart from the factory use with a dedicated cooling water circulation.
