Does anyone make a relatively inexpensive (US$500 or less) low voltage, CC/CV AC power supply (aka AC power source)? Ideally 0-36 V, 0-3 A, isolated output, V and A fine/coarse knobs and digital displays. Similar specs to those of countless inexpensive DC power supplies. Variable frequency, programmability, remote control, and polyphase are not needed. I have a variac, but it doesn’t meet the specs. And yes, variacs with digital V and A displays are available … but how about a CC control? When I need low voltage AC for testing, I use a fixed voltage, isolated-output transformer powered by a variac for voltage control. When current limiting is needed, I calculate the appropriate size resistor and use that in series. This is really a fixed power mode because the appropriate size resistor will depend on applied voltage. Pretty clunky compared to when I need similar DC voltage and current for testing … set V and A on HP, GW or BK supply, connect, and go.
AC supplies I’ve found that meet my specs cost upwards of US$1000 and have additional, unneeded features.
