TRF-220/12-25
Mounting
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
• Transformer for flush mounting. The transformer casing is made of plastic and supplied with
a protective terminal box. Electrical connection of
the fan with the safe voltage 12 V is done through
the output terminal block.
• Transformer is designed for indoor installation
in areas not subjected to high humidity and
temperature influence.
• Transformer is designed for ceiling flush
mounting or recess wall mounting. In case of
installation into a junction box provide sufficient
air ventilation to prevent the device overheating.
• Observe the applicable fire safety requirements
while installation and operation. Do not install
transformers above heating equipment.
• For overload protection the transformer is
equipped with a replaceable melting fuse built in
the input terminal board.
•
Protection rating (except terminal blocks) IP 40.
