So, ive had my laser for several years now. like everyone, ive had some of the common issues, PSU´s burning out, lens cracking, etc etc and the forum here is great (thanks to everyone here), so now i bring you my latest issue: Workshop Wiring!
currently, i have the workshop in my house. The electrical comes from the main breaker panel, to an outlet. A ¨terared 2,5kva stabilizer¨ is connected there, with 2 outlets in the back. There i have the laser plugged in, and the water chiller. From the laser, theres also outlets on the back, and thats where the air pump and fume extraction are connected.
i live in argentina, 220v electricity. To protect everything better, and make sure no surges keep causing me more unfortunate surprises, i was suggested in buying 4 items…
Gralf GF-SPD-T2-40 (Transient Surge Protection Device (SPD), 1P+N)
BAW c20 (2 pole circuit breaker)
BAW DF225-25A (Two-Pole Residual Current Circuit Breaker)
Geneve GE-PTD40 (40A Automatic Voltage Protection Device (220V, 1P+N))
the wiring is whats messing with me. How do i do this? Ive spoken to some people, checked with AI, and ive added in a drawing of what ive been suggested to do. Is it right??
Is it because you have a very unstable power grid, or why do you want to “complicate” this simple installation?
A quite normal residual current circuit breaker (I don’t know if the translation is correct), for each group does the service here in the house and in the rest of the country.
The picture shows an example
well i have a breaker like that here… the main circuit breaker…
i dont know! it didnt cost much.
what im told is that there are spikes…
like the current is 220v… but really it fluctuates between 210 and 230 (i guess?)
and theres times where its too high or too low, an actual spike, where it fries stuff
and sometimes theres other issues?
If you have power line fluctuations, a power line stabilizer will do. You do not need all that other stuff unless you are installing a dedicated outlet, which will not solve your problem.
I found this as an example, although I think Rs $4,692 (about $50 USD) is quite cheap.
I don’t know what exactly you’re attempting to do, but I agree with @bernd.dk to keep it simple (KISS principle.)
I don’t think you can do much with spikes and dropouts, except standard spike suppressors or filters.
Have you checked into a battery backup system? These prevent transients and short dropouts as they can generate 240V for your machines for a short period. They usually have input protection.
Where I originally worked, there was a pretty elaborate system of batteries, motor generators along with outside diesel generators. The motor generator was simply a very large cast iron fly wheel that drove the generators. Batteries keep everything powered up until the generators could start.
Flywheel inertia maintained a continuous 480V supply.
That’s a really good idea. If you can get an old UPS, they were used a lot in offices for a while. Even if the battery is bad, all the power will still be more stable and clean while it passes through the device, a kind of filter. But of course you won’t get the “emergency generator” function with a bad battery, but if it’s only peaks and voltage variations, then it’s definitely recommended.
