HY01D523B With the I/O (1 to 3 phase) voltage (180-250) ratings and Frequency 40-60 hertz, power at 1.5kw. The next line says output 3ph, 220 volt,10 amps, 0-400 Hz But the booklet in the box claims its an: ASKPOWER A131, and the pix looks almost but not exactly the same, as the pix has a pot to the right of the stop/reset button that this unit does not have. Now, here's something interesting, I ebay searched for that model number, and came up with the exact same HY etc number. But its rated at 2Kw, and _does_ have the resistor callouts on the customer interface according to the ebay pix! $129 + ship, about $30. Essentially the same as I paid for this one. Ok, so now I know they are available. And I'm a bit smarter about what I buy next time. So, this one, which seems to work and would be right at home on a gantry router, is officially for sale, first picture of Ben (on a $100 dollar bill + ship in my hand owns it. I paid about $160 for this one.
