    Description
    APPLICATION DESIGN
    • 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.
    • 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.
    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.
