when connected to the mains (125v) i can measure an output of 13v, so the ...?
ratio is 1 to 10, i'm building a power inverter with this transformer, so when i connect the 12.7v battery i would expect around 127v, or perhaps 110 considering the battery voltage drop, instead my multimeter reads a steady 222v, about double of what it should be,
what could be wrong?
could a higher or lower frequency than 60hz increase the voltage?
