From the circuit diagram (Page 62) of the board, it appears that there are two transformers. T002 is connected directly to the mains input and supplies DC and an AC Detect signal to the Main board via …

There are no standard commercial 24V power supplies that put out harmful radiation of any kind. Some cheaper ones may produce a bit of radio interference which, for example, you might pick up if you b …

If it is a USB power supply then it is likely that the output voltage is fixed at 5V. So talk of variable or multi-output supplies is irrelevant. Most likely it consumes 20W in order to deliver 15W = …

The short answer is no. One of your peltier devices will consume 12/3.3 A = 3.64A hence 10 of them require 36.36A. The 2 water pumps need 3.7 * 2 = 7.4A. So the total load would be 43.76A which exceed …

If you are powering your modules over a fairly long wire, when the relay actuates there will be an additional voltage drop across the power feed wires. Therefore I suggest you generate the required 5V …

There is no way that circuit will deliver -100V. The MEJ340 is just permanently turned on by the 10K resistor to its base, the unspecified capacitor does nothing. The 100K variable resistor is just fl …

Looking at the application notes The logic on the PCA9685 should be powered from the same supply as the Raspberry Pi (3 - 5V) Vcc and this is low power. The servos can have their own separate supply V …

If I had to guess, I'd say that the thick red and black wires are supposed to be wired in series with the load. I suggest between the positive side of C10 and the + output terminal, with or without an …

As far as I can see these power supplies can deliver 1200V and even "a few nF" could deliver quite a nasty shock at that voltage. Schaffner is being cautious, not wishing to surprise their customers, …

This question is almost impossible to answer completely. If you are absolutely certain that you will never want to light more than 10 LEDs at full brightness at any one time then you could get away wi …

Having explained where the 50V comes from in the other answer and comments there is another point you might consider when replacing the transformer. The design is such that the drop across R95 & R96 i …

Looking at the data sheets for the controller board and an Arduino Uno, you appear to have 2 options. You already have ground connected to all 3 as shown in the diagram. Run a wire from the 12V suppl …
