Hi!
"THE ALL NEW EST1500-N Power Supply is a replacement for EST1000 and EST1000N". Would anybody know from where I could find that?
With many thanks,
Katri
We did spend last week with my father rechecking / resoldering / revisioning two of EST1500-N Power Supply units (that is how I came to this post and we got 8 pcs from Jens 10 years ago with enlargers for big school darkroom project).
Only now we took 2 first "mint" units from the packaging for testing with CLS1840/2000.
Unit is not well made. Solder on some joints was already falling off. Soldering and mounting were made so sloppy that resonated with a sign "made in the USA" on the front and price Jens was paid.
100% solder joints were an absolute must for resoldering. With our huge experience with Durst-pro-USA "mint" equipment and service - that power supply was just one more proof-of-principle.
Technically the unit is rather simple and built (I could make images if you need or find some on "Durst CLS 1840, 220 volt equipment problem" thread on another forum) around one PWM regulator 50-75 USD priced, 4 time delay relays, 1 power SSR, 3 relays, 1 diod bridge, 24V tranformer, and regulator PCB knob connected with soldered wires. I think you could build one from scratch from photos. You need a plug for the head but I think you could take one from your previous one.
