There are several possibilities:
1) Your transformer does not deliver enough power (Watts), in which case
the voltage will drop under load. you may just need a bigger transformer.
2) If your 900 expects 50 Herz current, the 60 Herz current may confuse
the controller in the swithcing power supply.
By the way, most Amarican homes have 220V available at the fuse box. If
you are going to run 220V regularly, you may want to have a 220V circuit
installed and get a full 15 Amps. A quick cheap fix is to use the hot
lines from two different 110V circuits that are on opposite phases. A
simple volt meter will tell you which ones will work.
