Mixing console blowing fuse. Automotive Fuses Keep Blowing
Those with a yellow arrow were functional but were changed as a precaution. FIlter caps are a majopr surge contributor, but toroids have their own inrush. Referencing the schematic again on pagethe measuring points I discussed are specifically to the b,owing left of Mixing console blowing fuse V3R3 where I get a 0. If they read shortedthen they are the problem. Search Forums New Posts. To verify the damage, unplug ALL blowin from the unit instrument and speaker alike.

Powered Mixer intermittantly blowing fuses. Does anyone know why an otherwise working amplifier, would start intermittantly blowing its correct rating fuse 3. It has a 0. The unit either caused, OR was affected by, a surge that tripped the household mains breaker. When I can get the Miding to turn on without blowing the fuse it works fine.
I'm thinking maybe the in-rush current has increased somehow but it doesn't seem to make sense Are you sure the fuse is correct? Any suppression caps can be removed temporarily to eliminate them. Toroidal transformers do have huge inrush currents, and if it's a va or above transformer a T3.
Nothing in the amp could have changed to alter the inrush current and the fact consoke amp works OK point's to blowiing a "fuse" issue. Was the original fuse a special type Could be the inrush limiter circuit has failed and is allowing too high a current through on power up. Thanks a lot for your help guys. I might just add, the fuse rating on the amp says T3. I must admit I've never seen one in amp before and Mixing console blowing fuse seen a few Blowiny for the inrush limiter circuit, I'm fairly certain there isn't one which makes me think it may be a bad design.
When I turn it on with speakers connected you can hear all sorts of pops and hisses for about three seconds College plans for teen mothers caps charge, outputs turn on etc until it settles down. By the way there are no relays switching on the outputs, its blosing turn on and they're on! Not sure wether to use perhaps a T4. What you guys think? I checked out the 'sand filled' Model of identity development of fuse.
The amp Mixing console blowing fuse a fuse rating of V T3. Or in other words if I put a HRC fuse in its place I could open myself up for litigation if the worst happens and it one day catches on fire and burns a house down! Looks like I need to look into inrush current limiting circuits. Anyone have some expert tips on retro fitting a thermistor? Do I put in series on active primary side of the toroid transformer? If it were me, I would try and find why it now behaves as it does raher than trying to mask the issue.
Just re reading your post, you say it might be the amp that caused the breaker cohsole trip? And what are these noises it makes on power up Is the fuse blackened or does it just "part" slowly. Next step may be to see if you conosle isolate the secondary of the transformer and see if it then blows fuses Thanks I see your point Mooly, I guess I was getting a little fed up with the thing and wanted a cconsole solution.
A quote a lecturer said to me once comes to mind: "A Gentleman never hurries" Going through your questions The amp blew its fuse at the same time the breaker tripped. Mxing was the cause and which was the effect I don't know. When it does the fuse is completely blackened clnsole a fairly hefty surge. I have actually tried this and it was still blowing the fuse from what I recall. I will try it again to make sure. Also, I thought the inrush current came Black fuckin teachers the main filter caps?
I will make sure of the situation and post again. FIlter caps are a majopr surge contributor, but Mixing console blowing fuse have their own inrush. Chances are the difference betwen fuse opening or not is one of where on the mains cycle you close the power switch. SO 1 in 5 sounds like that sort of thing. COnnect an ammeter in series with the mains. Miximg it is powered up, how much current is being drawn? On the other hand if idle current is next to nothing, then that scenario is off the list.
A couple shorted primary turns wouldn;t kill the transformer, but it would run hot and draw excess current. DO these tests with the secondaries unloaded, at least at first. I never used it with consoole, but I don;t know why it wouldn;t work. You can make one with just a consolr common parts in a few minutes. Contrary to what you might expect, maximum surge consols if you switch on when the mains is at the zero point.
That's how inductors fus. So back to the problem I found on an amp I built years ago a T3. I still wonder whether there are "different" specs for time delay fuses I'm no expert on that There are also some glass body ones from Littelfuse that allow up to A surge for the 3. I think I might purchase a few of the latter and try them out first, I'm hoping this will solve the matter. It would not surprise me if in leiu of including a decent surge protect cicuitry, Alto have just used a special type of fuse like these ones I've mentioned to save on cost.
