Former lab technician here from a company that made such indicators back in the 1970's. All them clip cases are designed to be assembled once and disposed if they fail. Back in 1979 we experimented with all colours of LED available. We were the world's first to sell LED traffic lights. We also made panel light buzzer combinations. Customers wanted reliability as our products were used globally in cable cars, trains and busses so we had filament indicators with a 20 year lifespan and LED ones suggesting 30 years at the time. Buzzer frequency was precisely chosen not to reduce indicators lifespan avoiding any resonance. All our LED products had diodes especially chosen to have triple redundancy in reverse leakage to protect the LED's used. A 220V certified product for industry was tested at 660V for 24h. A medical product was each tested with 1000V for 24h to ensure failure was not an option. Manufacturers of the famous 1N4007 would return our money when diliveries were out of spec. So each technician could take home a box of 1000 such out of spec diodes. As per today I never managed to kill such a diode.

A triple LED indicator if they're all of the same color is very useful. You can use it to indicate which phases are working on a 3-phase system. In normal operation, all three lights should be on. If only one or two are on, you lost a phase or two and that's why things are going haywire. Losing a phase leads to so many oddball issues having a simple indicator showing that all 3 phases are energized is a remarkably useful utility. If you have 3 phase in your home (some places do), then installing such an indicator can help solve many issues.
@trabajoCARA
28 күн бұрын
In Chile these kind of indicators are required for each phase of a panel to be illuminated permanently when that panel is receiving power from the meter. We are required to place a fuse or low value circuit breaker (up to 10a, but a 1a or 2a breaker seems appropriate) protecting those indicators. If using a breaker I usually place a lock that prevents it from being disconnected by accident.
@BTW...
28 күн бұрын
The fuses or CB is NOT there to protect the indicator. They are there to protect the switchboard/distribution panel in case of a short circuit fault in the indicator or wiring. The secondary function is to isolate the indicator if any service work is needed after the fuses. You wouldn't want to pull main fuses and disconnect the whole board to work on the indicator module, would you. As you describe the application, without fuse (2A) the indicators are connected prior to any current limiting device to the full current supply potentials. The only fault limiter will be the main high current service fuses. Could be 63A... could be >800A. The instantaneous fault current level will be far higher than the main fuse rating. Could be around 6kA to 10kA. One flash... then ash. If a wiring fault from meter to the indicator occurs ( low current capacity wire) OR those small wires inside OR the LED board suffers short circuit the wire or indicator module will vaporise, spraying arc flame (and molten copper metal) all around the enclosure. Replace or rebuild the whole panel including a new revenue meter. Everyone will be upset and ask WTF questions. I see little point in CB lockoff. It will be obvious it has been manually switched off or tripped by handle position.
@trabajoCARA
28 күн бұрын
@@BTW... you are right, the little fuse/circuit breaker is mainly protecting the small gauge (~ 1,5 mm2) wire that’s feeding the indicators and the PCB inside. We don’t use main fuses for residential applications around here. Instead inside the enclosure of the meter the energy providers places a 6kA or 10kA circuit breaker rated for the service. I still think a lock around the circuit breaker that services the led indicator is useful. Mainly as a way of signaling the home owner that they should mess with that “toggle” as it does not directly control any receptacle/ useful load.

As stated by @BTW... do not protect the indicator. I remember once seeing a newish breaker in Ukraine that would not trip if held-up. Being born in post-comunist coutry learning on Czechoslovakian breakers from 80s 70s which would crack (become un-switchable by design) if locked ON when tripping. Modern European breakers do obviously switch off regardless, but I have seen some LVE and LAP or chinese fakes which noticeably slowed down with finger switching them on. So I would make sure that the breakers in Chile still trip-off if locked in ON position. Second: if human wants to switch something ON or Off then he will. Official process UK when inspecting or repairing circuits is to lock it. That doesn't work. Your average monkey with the trovel, quick-skim, roller or a spanner just take the locks off. The only safe way is to disconnect the wires from breakers output. locking set is like alkaline batteries instead of enelops, for NIC/Napit (your local electrical trading body) inspection whether you have right tools.

Today I decided to open the Aliexpress one to see what makes it tick (hope you're proud!). What I found seems like an outright scam hah. The PH meter has two probes but one of them is connected to literally nothing while the other probe goes into a tiny coil that serves as a meter. Only the first third of the switch seems to do anything. The middle setting has only a probe leg connected to it so I guess it works via brain wifi or something. Nothing connected to the last third of the switch that reads moisture content, supposedly. It's a green thingy with a 3 way switch and two probes that supposedly tells you the ph, light intensity and moisture content. Seems like only the light intensity part does anything but I would love for you to break one down for us so you can tell me exactly how badly I've been scammed, if at all! Much love :)

Intensity, since one resistor can run lots of LEDs in series at the same current.

If the diodes or LEDs fail short , then the resistor will still limit the current to reasonablly safe levels, but if the resistor fails short then there would be a massive over-current. A second resistor would make me feel much safer about the design.

The triple LED modules allow each LED to light individually.Clive just wired them all together to test them.

@@jeepien No, not phases. Just individual LEDs which can be used to indicate anything you like. They do not even have to be AC power, BigClive just tested them with line power because that was convenient for him. When I was building systems, I used red for power, yellow for data OK, and green for PLC watchdog OK at the maintenance remote office so the users did not have to go all the way to the closet to see if the system was running. Could have been for anything though.

The SMD resistors don't look big enough for the voltage across them. For an application like this, (240 VACrms) they should be at least 1206 size.

I think the RMS voltage of a half rectified sineave is 1/2 of the 240V .... So I think the resistor only sees about 110V RMS, and the power dissipation will therefore be 110^2/100k ~ 0.12 W
@petermichaelgreen

No, the RMS is the quare root of the mean of the square. So half wave rectification only reduces the RMS voltage by sqrt(2).

100k seems a little low, specially as it has a diode, 300v through it, no wonder it's bright! If diode, why you still call it alternating current, it's just really badly modukated dc 😅
