50hz transformer on 60hz
My cousin gave me telephone device bring from USA. AC adaptor was marked AC 120V, 60Hz, output 9V ~ 850mA, but mains in my country is 220V 50Hz. How can I use it? I try to use a transformer with output 110V, it works good but slightly hot after about 30'.
Thank you for viewing.
