• Low-voltage step-down transformers
are used in humid premises as bathroom
and kitchen with low-voltage (12 V) safety
requirements. TRF transformers are used to
provide safe power voltage 12 V/ 50 Hz for
the domestic fans not more than 16 W (25VA)
with current load up to 2 A.
time from 2 to 30 minutes
and a humidity sensor with
the threshold value from 60 to 90%.
KТР – equipped with a
regulated timer and a motion
sensor with the sensitivity
area from 1 to 4 m and the
detection angle up to 100°.
