Both outlets are limited to 10A, regardless of voltage. Since power = voltage × current, that's why the first one shows different power levels for different voltages. I assume that "AC" stands for "a …

You have a number of options. Given your evident level of expertise, the simplest thing to do is to get three separate AC-input power supplies: 12VDC - connect the negative terminal to ground - this …

Yes, any isolated DC-DC converter will work fine in this application. Just make sure you check its datasheet for the maximum input-to-output differential it is rated for. Most are at least 1500V, so y …

To be conservative, you should assume that the maximum power rating of the universal adapter occurs at the maximum output voltage, and that all lower output voltages are limited to the same current. …

I just to add to the other answers, which cover the basics fairly well, but ignore the input current waveform, which can be important in some applications. The current is drawn from the 12V supply in …

The strobing effect suggests that the power supply is sensing an overload, shutting down and then retrying. The additional resistance of the multimeter in current mode might be just enough to keep the …

They are implementing a "charge pump" that increases the available output current. It's easier to see if you redraw the circuit: simulate this circuit – Schematic created using CircuitLab When …

Just use a SPDT pushbutton: simulate this circuit – Schematic created using CircuitLab

A 24V, 60W bulb requires 2.5A of current. 25 such bulbs requires a total of 62.5A. If you want to deliver this current with a voltage drop of no more than 10% (2.4V), then you need to use wires that …

Yes, you can exchange voltage for current (and vice-versa), but there is always some power loss in the process, so the total input power will be somewhat higher than the power consumed by the end devi …

The simplest thing to do would be to temporarily use a large 6V power supply — one that can supply several amps — and measure the current that the lamp draws. Borrow the use of such a supply and a mul …

160V is not enough margin for this application. The nominal peak voltage coming out of your rectifier is 155V, and if your line voltage goes 10% high, you'll exceed the rating of the capacitor. Use at …

Those older chargers are very simple — just a transformer and a rectifier, no filter. The output is pulsating rather than what we would consider "pure DC". Therefore, it makes a certain amount of sens …

The filter prevents the noise that the digital logic of the MCU itself generates from affecting the sensitive analog sections of the chip — the ADC and the PLL. The rest of the power supply chain does …

I know nothing about that part of the business, but just thinking about it for a few seconds, it seems to me that the primary use of short-term predictions is to inform the scheduling of fuel deliveri …
