Just a heads up. Your pictures did not make it. I believe that they are blocked in this group? Chris VE3CEA Get Outlook for iOS<https://aka.ms/o0ukef> ________________________________ From: Amps <amp
Well, if a MOV is only available best placement is line to neutral thus protecting the powered equipment from basic power line differential spikes. To achieve better protection three MOVs are to me u

Could use a serial converter, say from RS232 to RS422 and then convert it back at the amp. 422 is common in industrial environments for range and noise cancelling. A few commercial computer suppliers

Oops trying again Sent from my iPhone I repaired equipment that used them in various places. Found the pem nuts to be both good and bad. If they were installed in the correct environment where the kn
Hey there, Quick glance at the schematic makes me think you may have a open fuse in your slow start section. Try checking F3, F4, or the associated resistors. Chris VE3CEA Sent from my iPhone _______
Not too odd really. On 120v it is possible to run the initial startup cycle on just one of the two windings. Then once the soft start circuit bypasses then both windings come into operation and unit
Interesting that the board is stencilled lower. If it still regularly blows the one particular fuse, then further investigation may be warranted. If the fuse failure indicates simple overload ( not s

I did notice that all the others read as preliminary data sheets. Maybe they thought originally it would be suitable for amplification. I did find a different link that seemed to load better. https:/
