Hi. I'm joining this forum to ask about some equipment I need. At the community college where I teach, we do a lab in freshman physics where students measure the input to and output from a transformer. My AC sources are reaching the end of their lives, so I'm looking for replacements. As far as I can tell, what I need is
110 V at 60 Hz input
0 to 15 or 20 V output in at least four steps (e.g., 4 V, 8 V, 12 V, 16 V)
Current up to at least 1.5 A
Reasonably sinusoidal output, not clipped or chopped, at all voltages
Output easily connected to banana plugs or alligator clips
Price no more than a few hundred U.S. dollars
What I'd like, more or less in decreasing order of importance, is
Output voltage limited or limitable to something definitely less than 100 V
Good quality--steady output voltage, long life even if bumped, easy fine adjustment, anything else that comes to mind
Continuously adjustable output voltage
DC operation with an on-off switch (for another part of the lab)
Accurate digital meters of output V and I
Can anyone suggest anything?
Thanks in advance.
