The power supply of the brand "ednet.", model "AD-75WXX-XXX" is as described in the output voltage range 16-24V on 15-28V expand.
There are battery tanks (mobile battery) in different sizes and styles. Equipped with (at least) a lithium ion cell (E.g. 18650) they deliver 5V at output (for.5A). A charging circuit are integrated (CV/CC procedure), a Step-Up Converter as well as a protection circuit against deep discharge. The latter is...
The operation of power LEDs calls for constant current source for higher performance. (> = 1A) As an example, of operating a 30W was shown LED to a modified Step-Up Converter (boost) here.
It scans a 250 GB platter with the laser scanner, the following picture emerges. The "Roughness" or amplitude is in the range -0 1µm. However, has dust according to definition a particle size of 2.5 10 µm, thus 25-100 is greater. This is one reason, among others...
Who a hedgehog 3200 LX thin client or identical device (for example, CA9, various HP Neoware) with the motherboard-code "WinNet G260 v1. 0 ' owns, may determine that this after connecting the power plug either at all or dirty boots. This is a...
Conceived and designed by Markus Frejek, every hobbyist knows well this problem: one expands a transistor out of a unit or extracting a Pocket from the Junk box. If the designation is to identify (and one is known), everything is...
