Main Power
Your VacTrac™ Series 12-station controller system can operate
from a 115 VAC or 220 VAC source at 50 Hz or 60 Hz. The main
power switch on the controller is located on the right side of the
housing. Built into the power switch are the controller fuses. Also,
the configuration of the fuse holder determines the voltage setting
of the controller (115/220 VAC).
Marked on the faceplate of the fuse holder shows the configuration
for the desired voltage. Using a small screwdriver, remove the fuse
holder. To select the operating voltage, align the arrow marker on
the holder and the switch as shown in the following section.
The VacTrac 12 station controller has a standard IEC power cord.
Plug the cord into any standard 115 VAC outlet. If you selected the
220 VAC option, remove the end connector and install a standard
220 VAC plug. Doing so does not effect the controllers warranty.
DC Controller Power Sources
Although main controller power is 115/220 VAC, control power is
actually unregulated 24 VDC. The 24 VDC control power supplies
the power for all solenoids, sensors, and the controller itself. The
unregulated supply can deliver up to five (5) amps of continuous
current to drive a very large system.
