Evening.
I've just bought my self a CT meter off ebay.
The display is an LCD screen with backlight, so requires a power supply.
It requires ~12mA at 12V
The stated input range is between 8V and 12V AC or DC.
Would a resistor be suitable to reduce the voltage for this, and if so, what size might I need, or am I being crazy and ought to use a small transformer?
Thanks in advance
