Junction box for the control of a couple of fans

With this easy and economic system is possible to control
directly by the thermometric device or any relay with a clean contact,
a pair of fans.

Each bar is fitted with:

• Two fuse protection (one for each fan bar)
• One power relay that controls the switch on and off of the fans

The device is mounted directly from the factory on one of the
standard fans in any size.
It’s enough to have a 230V AC power source and a run signal
from the thermometric device to fully manage the ventilation
of the transformer.
