Fan Control Centers
MARS series 240 fan centers provide convenient low voltage control
o
f one and two speed fan motors and auxiliary circuits in heating,
cooling, or heating/cooling applications. Each MARS fan center is a
reliable, compact unit consisting of a 24 volt control transformer and
a plug-in switching relay mounted on a 4” square electrical junction
box cover. All line voltage connections are made inside the box with
color coded pre-stripped leads. Low voltage connections are made
at a convenient terminal board mounted to the transformer.
Features:
• Choice of SPDT, SPNO / SPNC or DPDT relay switching options
• UL 1585 40VA transformer
• Color coded leads
• Low voltage terminal board
• Mounts directly to 4” electrical box
• 50/60 Hertz
