• dissipation of device thermic power with effects on installation
room temperature.
• thermal power dissipation with limits on installation room tem-
perature.
• requires exchange with external air or an air conditioner to tran-
sfer dissipated power outside the panel.
• maximum limits of voltage and derived power of transients on
the line, for which the solid state power unit contains protective
devices (based on the model).

ATTENTION
This product has been designed for class A equipment. Use of the product in domestic environments may cause radio
interference, in which case the user may be required to employ additional mitigation methods.
EMC filters are required in PA mode (Phase Angle, i.e., SCR trigger with phase angle modulation).
The filter model and current level depend on the configuration and load used.
The power filter MUST by connected as close as possible to the GTF.
You can use a filter connected between the power line and GTF or an LC group connected between the GTF output and the load.

• presence of dispersion current in GTF in non-conducting state
(current of a few mA due to RC Snubber circuit to protect the
thyristor).
GEFRAN S.p.A. assumes no liability for any
damage to persons or property deriving from
tampering, from incorrect or improper use, or
