Application
• 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.
Design
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°.
•
TRF-220/12-25 К transformer in plastic
casing for wall mounting.
• TRF-220/12-25 КV transformer in plastic
casing for wall mounting with a built-in switch.
The casing is equipped with a light indicator.
• For overload protection the transformer is
equipped with a replaceable melting fuse.
Modifications and options
KV – equipped with a pull cord
switch.
Mounting
•
Transformer is designed for indoor
installation in areas not subjected to high
humidity and temperature influence.
• Transformer is designed for wall mounting.
Provide sufficient air circulation for cooling of
the internal circuits.
• Observe the applicable fire safety
requirements while installation and operation.
Do not install transformers above heating
equipment.
KT – equipped with a regulated timer
with the operating time from 2 to 30
minutes.
