5.3 Voltage Selection and Fuse Rating
The Magstim Rapid
2
may be operated from supplies in the range of 115V ± 10% ~ 60Hz, 230V ± 10%
~ 50Hz and 240V ± 10% ~ 60Hz. The voltage selector on the rear panel of the Main Frame and if
relevant, the Magstim Plus
1
along with the associated fuses must correspond to the supply voltage as
indicated in the table below. The PSU, however, is not voltage selectable and is manufactured as
either a 230V (240V) ± 10% unit, or a 115V ± 10% unit. The two are not interchangeable.
