Heating and Ventilation of the interior of the Power
Supply Unit
This module is u
sed in case the “ZUP” power supply unit is installed outside the building,
in a zone characterized with high temperature changes, or if the power supply unit is equipped
with fan power supply modules with frequency converters. The module consists of two
independent mechanical thermostats
–
one activates the ventilation fan and the other one
activates cabinet heaters.
This way the user can separately set the activation temperature for ventilation and the
activation temperature for heating the Power Supply Unit interior.
The ventilation-heating module is equipped with an auxiliary contact in the overcurrent
protection device, which makes it possible to detect the failure of the supply line or of one of
the module elements. The power of the fan and hea
ters matches the size of the “ZUP” power
supply unit housing, its version (double housing walls for the outdoor version) and expected
ambient temperature.
