Panel Mount Voltage Regulator / Knob

[irving2008]

I'v just had a quick look on ebay and found this:

This is the kind of thing i was thinking, i would prefer to change the output via a front panel using a knob, over poping inside the unit to change the dip switches everytime i need a new output amount.

Well its a pretty voltmeter, but its not a voltage regulator...the way its described is misleading. It has a built-in regulator allowing it to be powered from a 5 - 15v supply - while reading that supply... so it can be used as a supply monitor.

Its not autoranging tho, so not much use for monitoring a truely variable power supply.

So lets start by listing what you want...

A power unit with an adjustable output voltage from 0 to 25v is a good range for hobby stuff, switched in 2.5 volt steps maybe ?

Output current at 5A maximum, current limited. Maybe a switched limiter, for .1,.5,1 and 5A?

Output voltage and current monitoring, current limit warning (LED, buzzer?)

What else?

What transformers etc have you got to start the ball rolling?
