Thanks IRstuff. I came across the NTE part with a home project in mind and liked the variable voltage/current in a quick and easy package. I wanted to keep a low cost trickle charge, ~1.5A, 13.5V, on a lead acid battery from a somewhat distant 24VAC 1250mA outdoor low voltage transformer (CODE...

Hello - I'm trying to cross reference back an NTE1942 linear voltage regulator. I called NTE and they can't uncross a device. Does this device look familiar to anyone that might know the original device? I've looked at most every Semiconductor Manufacturers linear regulators product line...

I did a quick search on 'motion sensors' looking for information on what their principal method of operation is. I didn't get any hits so I ask: I believe they use infrared sensors, not sure what else is available - cheaply and accurately. My question is what wavelength do the IR sensors...

How is the speed control handled in cordless drills? Is it more than just a variable resistor - active circuit, or not? TIA

An inverter would be nice but I think I can keep cost down and battery capacity up with some of the other methods! Thanks again, I've got a much clearer picture and probably some new/old questions where I failed my education - lol.

First, thanks to all for the alternative product websites and suggestions as well as identifying what the device might be. Unfortunately without knowing what the output controlling device is, if there is one at all, experimentation would be necessary if specifications or documentation, on the...

There is a selectable time delay, either 1 minute or 10 minutes, that works fine when 120VAC is switched through the the sensor adapter relay. It's when the sensor adapter relay tries to switch a 12VDC load that the sensor adapter relay never drops out. If I remove the load after the slected...

Hello, My question deals with a GE wireless Outdoor Motion-Sensor Light Adapter. The part number is PIR612A. Now as all good engineers, I using this product differently than its intended design. Instead of using it to sense motion and turn on a 120 VAC light I would like to use it to sense...
