Controller Class-2, Plug-in AC Transformer:
The AC transformer, used in Galaxy’s UL-listed controller, is a Class-2, plug-in type transformer with fused
secondary. The transformer is UL-listed and CSA Certified and can be plugged into a duplex plug. The
transformer should be Input-rated 120 VAC/49 VA at 60 Hz; Output rated 16.5 VAC/40VA at 60 Hz.
The transformer requires 1 pair of 18 AWG wire (minimum).
The transformer must be plugged into the 110VAC non-switched, duplex outlet and must
not

other equipment. Galaxy access control panels that require AC transformers are only intended for use with a UL
Listed, Class-2 transformer, like the one manufactured by
