The specs show it has a wide range of input freq and voltage. So even if your 92vac has large overshoots it probably will run on it. I haven't seen a power pack pictured or mentioned so it probably will not work on direct 12v.

Thanks for the info... I wish it said 90-240 VAC The 2 that do not work right say 100-240. The others that do, and I can get to, show 90 volts at the lower limit. The "switching" power supplies usually handle the inverter quite well, the straight regulated often have problems.
When budget allows, I tythink I will try one!
